database presentation topics

Distributed SQL includes distributed queries and distributed transactions. The primary objective of these changes is to improve performance, manageability, and functionality. Thus, Oracle Database provides an infrastructure for application developers to integrate data mining seamlessly with database applications. Such attacks identify redacted columns and, by process of elimination, try to back into actual data by repeating SQL queries that guess at stored values. Profiles provide a single point of reference for users that share a set of attributes. Streams can also be used to exchange data for particular tables with non-Oracle databases. In the extreme case, an Oracle RAC system provides database service even when all but one node is down. The dilemma about the topic selection gets aggravated further when a guide demands the selection of a … Also, you can administer objects when auditing statements and schema objects. A site failure may affect all processing at a data center, or a subset of applications supported by a data center. The service level impact of a human error outage can vary significantly depending on the amount and critical nature of the affected data. Topics: Climate, Governance Creating a Sustainable Food Future: Improving Productivity and Environmental Performance of Aquaculture We examine the implications of doubling aquaculture production between now and 2050, and offer recommendations to ensure that aquaculture growth contributes to a sustainable food future. Aggregation is fundamental to data warehousing. Oracle RAC, Grid computing, and Oracle VPD can enable you to consolidate information into a single database. Encrypting data on the network prevents this sort of activity. Oracle Database Security Guide and Oracle Database Advanced Security Administrator's Guide for more information about authentication methods, Oracle Database Administrator's Guide to learn about administrative authentication. Table functions provide support for pipelined and parallel execution of transformations implemented in PL/SQL, C, or Java without requiring the use of intermediate staging tables. You will get an idea of various farming related presentation topics. See Oracle Database Advanced Application Developer's Guide. Additional systems accessed by this user are remote systems. The Oracle distributed database architecture provides query and transaction transparency. Examples of storage failures include the failure of a disk drive or storage array. Dr. Michalis Petropoulos, Assistant Professor ; Description. Rules determine which changes are captured. Planned downtime can be categorized by its causes: Planned system changes occur when you perform routine and periodic maintenance operations and new deployments, including scheduled changes to the operating environment that occur outside of the organizational data structure in the database. SCAN enables clients to connect to the database service without regard for its location within the grid. Thus, after data has entered into the warehouse, data should not change. For example, it does not prevent directly connected, privileged users from performing inference attacks on redacted data. Figure 17-7 Oracle Streams Information Flow. A data warehouse is a relational database designed for query and analysis rather than for transaction processing. We return to the connection overview and see that the new sql connection was added. The fast start fault recovery technology in Oracle Database automatically bounds database instance recovery time. For example, a SQL statement that directly accesses a remote target through a gateway can concatenate two columns as part of the SELECT statement. Oracle Database provides different authentication methods, including the following: Oracle database can authenticate users using a password, Kerberos ticket, or PKI certificate. After being enqueued, messages can be transformed and propagated before being dequeued to the partner's application. You can dynamically allocate and deallocate these resources based on business priorities. "Oracle Automatic Storage Management (Oracle ASM)", Oracle Database High Availability Overview for an overview of the Database Storage Grid, Oracle Automatic Storage Management Administrator's Guide for more information about clustered Oracle ASM. For a sample use case, assume that a company uses Oracle Streams to maintain multiple copies of a corporate Web site. An intruder can use a network packet sniffer to capture information as it travels on the network, and then spool it to a file for malicious use. A staging area simplifies the tasks of building summaries and managing the warehouse. In Oracle Database, database authentication is the process by which a user presents credentials to the database, which verifies the credentials and allows access to the database. It includes support for scalar data types, Oracle Database object types with inheritance, XMLType with additional operators for XML data, and ANYDATA. Summaries are also called materialized views. Stores many months or years of data to support historical analysis. Propagations can send messages from one queue to another. Uses denormalized or partially denormalized schemas (such as a star schema) to optimize query performance. Oracle Real Application Clusters (Oracle RAC) enables multiple instances that are linked by an interconnect to share access to an Oracle database. Learn new and interesting things. With google presentation you can access and add to your presentation virtually anywhere with internet. Changes captured in each region are then forwarded to each of the other region's databases. Oracle Database provides several technologies to support business intelligence operations. Profiles can limit the number of concurrent sessions for a user, CPU processing time available for each session, and amount of logical I/O available (see "Buffer I/O"). Examples include adding or removing CPUs and cluster nodes (a node is a computer on which a database instance resides), upgrading system hardware or software, and migrating the system platform. ISPOR Presentations Database This searchable resource includes more than 50,000 citable research abstracts of podium and poster presentations from ISPOR conferences that were published in Value in Health since 1998 in addition to recent non-citable session presentations from the Society’s conferences. It also includes features that enable end users to recover from problems without administrator involvement. In this case, it is important to design a system to minimize planned interruptions such as routine operations, periodic maintenance, and new deployments. 1. Oracle Real Application Clusters Administration and Deployment Guide to learn more about automatic workload management, Oracle Database High Availability Best Practices for an overview of fault tolerance in Oracle RAC. In addition to Oracle Data Guard, solutions for storage failures include the following: Oracle Automatic Storage Management (Oracle ASM). Presentation leadership & engineering mgmt. Data warehouses must put data from disparate sources into a consistent format. Section 501 A regular expression can redact data based on a search pattern. Oracle Streams is the asynchronous information sharing infrastructure in Oracle Database. In a bi-directional replication environment, both databases can allow changes to the replicated objects. Actividades de liderazgo y Juegos para desarrollar el trabajo en equipo lovingcommunity79. Now customize the name of a clipboard to store your clips. Oracle Real Application Clusters Administration and Deployment Guide to learn more about Cache Fusion, Oracle Database Installation Guide to learn how to install Grid Plug and Play. In the policy, specify a predefined redaction function. Oracle Database provides many techniques to control access to data. Get ideas for your own presentations. For example, you can partition data in a sales view by country and perform a model computation, as defined by multiple rules, on each country. The employees synonym hides the identity and location of the remote schema object. For example, these analytic functions enable you to calculate rankings and percentiles and moving windows. Browse free Contemporary information technology research project topics and materials in Nigeria. The type of authentication must be specified when a user is created in the Oracle database. For example, CREATE USER and CREATE SESSION are system privileges. Looks like you’ve clipped this slide to already. Components in the Oracle Database software stack, including the database instance, listener, and Oracle ASM instance, can restart automatically after a component failure or whenever the database host computer restarts. File Upload webhostingguy. This section focuses on Oracle solutions for federating and sharing information. See "Memory Management". This chapter contains the following sections: Overview of Data Warehousing and Business Intelligence, Overview of Oracle Information Integration. If you continue browsing the site, you agree to the use of cookies on this website. Take a look at these great reusable presentation templates created by members of the Prezi community. Because the physical nodes run independently, the failure of one or more nodes does not affect other nodes in the cluster. A database link is a connection between two physical databases that enables a client to access them as one logical database. A database is typically represented by a cylindrical diagram. A good design should enhance a presentation, not distract from it. For example, Oracle Database monitors the operating system to detect changes in the number of CPUs. End users directly access data that was transported from several source systems to the data warehouse. All the data can be simultaneously accessed and modified. Updated on a regular basis by the ETL process using bulk data modification techniques. Figure 17-7 depicts the basic information flow in a replication environment. Presentation on Database Management System (DBMS) Powerpoint PPTs; Results 1 to 1 of 1 . See Oracle Database Data Warehousing Guide to learn about SQL modeling. This form of encryption is transparent, provides high performance, and is easy to implement. To detect and prevent inference and other attacks originating from privileged users, Oracle recommends pairing Oracle Data Redaction with related database security products such as Oracle Audit Vault and Database Firewall, and Oracle Database Vault. You can use regular expressions for both full and partial redaction. Replication is the process of sharing database objects and data at multiple databases. Oracle Database Security Guide to learn how to manage resources with profiles, Oracle Database SQL Language Reference for CREATE PROFILE syntax and semantics. Oracle Streams Advanced Queuing supports all the standard features of message queuing systems. The importance of high availability in a database environment is tied to the cost of downtime, which is the time that a resource is unavailable. PRESENTATION OF TOPICS IIB THESES ASSIGNMENT , DECEMBER 11TH, 2020 2. At each regional database, an Oracle Streams apply process applies the changes automatically. Database management system or DBMS is used to maintain data and provide different solutions for managing data in different applications. For example, Oracle Database supports the following forms of analytic SQL: Aggregate functions such as COUNT return a single result row based on groups of rows rather than on single rows. Maintaining one or more standby databases in a Data Guard environment enables you to provide continuous database service if the production site fails. Figure 17-3 shows both the metadata and raw data of a traditional OLTP system and summary data. Unplanned downtime can be categorized by its causes: A site failure occurs when an event causes all or a significant portion of an application to stop processing or slow to an unusable service level. 14 Outstanding Sport Management Dissertation Topics. When users select the column, the data is decrypted. Slides for Database Management Systems, Third Edition. This section summarizes some of these techniques. This database is a fully functional Oracle database that has a read-only copy of the relevant application tables. You may not know the workload of your data warehouse in advance, so it should be optimized to perform well for a wide variety of possible queries. Oracle Streams is used to replicate data in an n-way configuration consisting of sites in New York, London, and Tokyo. Proper citation depends on your preferred or required style manual. Examples include table redefinition, adding table partitions, and creating or rebuilding indexes. With Oracle Data Mining, the data, data preparation, model building, and model scoring results all remain in the database. Visit Edusson Samples to brainstorm possible research paper topics and find relevant paper examples. For example, a data warehouse could track historical stock prices or income tax records. However, this technique can be time-consuming, and the backup may not be current. As shown in Figure 17-7, Oracle Streams contains the following basic elements: Oracle Streams can implicitly capture DML and DDL changes. Oracle Database minimizes downtime for data changes through online reorganization and redefinition. MIS 6326: DATABASE MANAGEMENT SYSTEMS Spring 2000 Final Presentations Instructor: Dr. Sumit Sarkar (Email: sumit@utdallas.edu) * Please select Sec501 or Sec502 to check the list of the group members. For example, a volume manager error causes bad disk read or writes. Clipping is a handy way to collect important slides you want to go back to later. If the primary database is unavailable because of an outage, then Data Guard can switch any standby database to the primary role, minimizing downtime. ASM partitions the disk space and evenly distributes the data across the disks provided to ASM. When a user inserts data into an encrypted column, the database automatically encrypts the data. Privilege types are defined by the database. ... tendencies based on the Global Trade Alert database (required data is publicly available) (Master) The behavioral view on the firm in the domain of International Business: a bibliometric analysis For example, the number 1234567 can appear as 83933895. In the context of system resources, a user profile is a named set of resource limits and password parameters that restrict database usage and instance resources for a user. Lost write detection is most effective when used with Data Guard. Examples of computers failures include hardware and operating system failures. Oracle Database Data Warehousing Guide to learn about Change Data Capture, Oracle Warehouse Builder Data Modeling, ETL, and Data Quality Guide for an overview of ETL. DataBase Intellegence Presentation Alexandr Zhuravlev. However, Oracle Database provides a rich set of capabilities usable by ETL tools such as Oracle Warehouse Builder and customized ETL solutions. A financial analyst can query the data marts for historical information about purchases and sales. Use the DBMS_REDACT package to create a redaction policy for a specified table. Hiring online help for creating PowerPoint presentations is thus the only way to deal with this issue since you get professionals to handle the task for you. Oracle Restart ensures that Oracle components are started in the proper order, in accordance with component dependencies. You can share information, which lets you maintain the information in multiple data stores and applications. These operations require SYSDBA or SYSOPER privileges (see "Connection with Administrator Privileges"). You can restore the database to another host. Oracle Enterprise Manager (Enterprise Manager) enables you to view and configure audit-related initialization parameters. As changes are applied, Oracle Streams checks for and resolves any conflicts. ETL capabilities provided by Oracle Database include: You can transport tablespaces between different computer architectures and operating systems. This architecture enables you to perform the following tasks when the database is open: Perform online table redefinition, which enables you to make table structure modifications without significantly affecting the availability of the table, Create, analyze, and reorganize indexes (see Chapter 3, "Indexes and Index-Organized Tables"), Move table partitions (see "Overview of Partitions"). Engage New Employees from Day 1 with our Onboarding Prezi Template! Figure 17-5 separates purchasing, sales, and inventory information into independent data marts. Your applications might be specifically tuned or designed to support only these operations. See Oracle Database Data Warehousing Guide to learn about table functions. Unlike VPD, OLS provides an out-of-the-box security policy and the metadata repository for defining and storing labels. In general, database security involves user authentication, encryption, access control, and monitoring. Research Clue Inc. is a web based company that provides research project writing guides/tips, data analysis softwares, research/writing jobs and research project topics with available materials. Enabling future accountability for current actions, Deterring users (or others, such as intruders) from inappropriate actions based on their accountability, Investigating, monitoring, and recording suspicious activity, Addressing auditing requirements for compliance, Oracle Database 2 Day + Security Guide and Oracle Database Security Guide to learn how to enable and disable auditing, Oracle Label Security Administrator's Guide to learn about Oracle Label Security auditing, which supplements standard auditing. A storage failure outage occurs when the storage holding some or all of the database contents becomes unavailable because it has shut down or is no longer accessible. However, the following types of replication environments are the most common: Only two databases share the replicated database objects. If you continue browsing the site, you agree to the use of cookies on this website. Reliability, recoverability, timely error detection, and continuous operations are the primary characteristics of high availability. Figure 17-4 Architecture of a Data Warehouse with a Staging Area. Privileges can be divided into the following categories: This is the right to perform a specific action in the database, or perform an action on any objects of a specific type. You can create user accounts as needed. Oracle ASM automates and simplifies the layout of data files, control files, and log files by automatically distributing them across all available disks. Alternatively, you can use fine-grained auditing to monitor specific database activities, such as actions on a database table or times that activities occur. Oracle Database supports the installation of database software upgrades, and the application of patchsets, in a rolling fashion—with near zero database downtime—by using Data Guard SQL Apply and logical standby databases. Oracle Database uses database links to enable users on one database to access objects in a remote database. With this capability, an application is immediately notified of any failure through the pool that terminates the connection. See our User Agreement and Privacy Policy. These messages alert employees at the warehouse about the orders so that they can fill and ship them. Oracle Database accomplishes this task by changing (redefining) database objects in a private environment known as an edition. As an organization evolves, it becomes increasingly important for it to be able to share information among multiple databases and applications. Figure 17-9 illustrates this Streams configuration. Oracle Database provides high availability solutions to prevent, tolerate, and reduce downtime for all types of unplanned failures. The Recovery Manager (RMAN) utility can back up data, restore data from a previous backup, and recover changes to that data up to the time before the failure occurred (see "Backup and Recovery"). Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Authentication also enables accountability by making it possible to link access and actions to specific identities. The Oracle Messaging Gateway integrates Oracle Database applications with other message queuing systems, such as Websphere MQ and Tibco. The use of table compression often leads to a better scaleup for read-only operations and faster query execution. Data must be shared with applications hosted on a Sybase database. One rule could calculate the sales of a product in 2011 as the sum of sales in 2009 and 2010. A role is a named group of related privileges that you grant to users or other roles. Support for explicit dequeue allows developers to use Oracle Streams to reliably exchange messages. Oracle Database provides a wide range of security tools to control user access to application data by authenticating users and then allowing administrators to grant users only those privileges required to perform their duties (see "Overview of Database Security"). Hi Dawood, you can see the presentation in the embedded prezi window in the post. Oracle Streams enables you to configure many different types of custom replication environments. The roles PAY_CLERK, MANAGER, and REC_CLERK are assigned to different users. Transparent data encryption includes industry-standard encryption algorithms such as the Advanced Encryption Standard (AES) and built-in key management. A role helps manage privileges for a database application or user group. For example, you can perform: Fine-grained surgical analysis and repair for localized damage, Rapid correction of more widespread damage, Recovery at the row, transaction, table, tablespace, and database level. For this reason, whenever they attempt to create a PowerPoint, it ends up being unimpressive. Several database components and utilities, including RMAN, can detect a corrupt block and record it in V$DATABASE_BLOCK_CORRUPTION. A common cause of unplanned downtime is a system fault or crash. Fault tolerance is the protection provided by a high availability architecture against the failure of a component in the architecture. For example, Enterprise Manager enables you to display and search for the properties of current audited statements, privileges, and objects. It conducts public opinion polling, demographic research, media content analysis and other empirical social science research. Information is organized by state and crop type for easy access. Examples include an extended site-wide power or network failure, a natural disaster making a data center inoperable, or a malicious attack on operations or the site. OLAP enables analysts to quickly obtain answers to complex, iterative queries during interactive sessions. For example, the clerk profile could limit a user to system resources required for clerical tasks. This feature efficiently identifies and captures data that has been added to, updated in, or removed from, relational tables and makes this change data available for use by applications or individuals. LCRs are placed in a staging area, which is a queue that stores and manages captured messages. A local user can access a link to a remote database without being a user on the remote database. Andreia Durães. Topics Presentation Topics This is a comprehensive list of more than 200 healthcare and Medical Presentation Topics is useful for Powerpoint PPT & Paper Presentations. Transforming and consolidating data from multiple locations. Thread: Presentation on Database Management System (DBMS) Powerpoint PPTs. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Oracle Database Data Warehousing Guide for a more detailed description of a database warehouse, Oracle Database VLDB and Partitioning Guide for a more detailed description of an OLTP system. The OLTP database is always up to date and reflects the current state of each business transaction. Oracle Audit Vault and Database Firewall (Oracle AVDF) provide a first line of defense for databases and consolidate audit data from databases, operating systems, and directories. A typical environment includes an ETL solution, an OLAP engine, Oracle Warehouse Builder, client analysis tools, and other applications that gather data and deliver it to users. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. OND PROJECT MATERIALS │HND PROJECTS │BSC PROJECTS │MBA PROJECT THESIS POST GRADUATE DIPLOMA . External tables enable external data to be joined directly and in parallel without requiring it to be first loaded in the database (see "External Tables"). Oracle Database is not itself an ETL tool. Oracle Data Redaction is a part of Oracle Advanced Security. Figure 17-4 shows a data warehouse with a staging area, which is a place where data is preprocessed before entering the warehouse. For example, credit card numbers, social security numbers, or patient health information must be encrypted. In general, database access control involves restricting data access and database activities. A block corruption is a data block that is not in a recognized Oracle format, or whose contents are not internally consistent. Changes are formatted into logical change records (LCRs), which are messages with a specific format describing a database change. Each server looks like any standalone server. A user privilege is the right to run specific SQL statements. In addition to Data Guard and Recovery Manager, Oracle Database supports the following forms of protection against data corruption: A data block lost write occurs when an I/O subsystem acknowledges the completion of the block write when the write did not occur. For example, a user may request the total sales for all customers last month. The London site also serves as the master site for several updatable materialized view sites. Dimensional objects are stored in Oracle Database in their native multidimensional format. An Oracle distributed database system can be transparent to users, making it appear as a single Oracle database. Thus, external tables enable the pipelining of the loading phase with the transformation phase. A database link is a connection between two physical databases that enables a client to access them as one logical database. Automated distributions of data files, control files, and online redo log files. Figure 17-8 shows a sample application that explicitly enqueues and dequeues messages through Advanced Queuing, enabling it to share information with partners using different messaging systems. If the CPU_COUNT initialization parameter is set to the default, then the database workload can dynamically take advantage of newly added processors. With our vast data base, students can have access to numerous term papers, Seminar … The queues can reside in the same or different databases. You can incrementally add nodes to a cluster instead of replacing existing systems with larger nodes. Oracle Database recommends the following forms of protection against human error: The best way to prevent errors is to restrict user access to data and services. This architecture allows a group of nodes to be transparently put online or taken offline, for maintenance, while the rest of the cluster continues to provide database service. The ADF data model is the core of how ADF interacts with the database, presents data to applications, contains application business logic, binds database results to the presentation tier, controls application page flow, and displays results to the client. Typical applications of data mining include call centers, ATMs, E-business relational management (ERM), and business planning. O discurso da qualidade e a qualidade do discurso. Downtime can be categorized as either planned or unplanned. For example, Oracle Streams propagates an update to an employees table to an identical employees table in a different database. When an order is entered, the business uses AQ to send the order ID and order date to a database in a warehouse. End users of a data warehouse do not directly update the database. Essentially, the database adds a dynamic WHERE clause to a SQL statement issued against the table, view, or synonym to which an Oracle VPD security policy was applied. Share yours for free! Oracle online analytical processing (OLAP) provides native multidimensional storage and rapid response times when analyzing data across multiple dimensions. When they achieve this goal, they are said to be integrated. Advanced Queuing stores user messages in abstract storage units called queues. Oracle Advanced Security Transparent Data Encryption enables you to encrypt individual table columns or a tablespace. Figure 17-3 Architecture of a Data Warehouse. A SQL grammar-based engine monitors and blocks unauthorized SQL traffic before it reaches the database. They can also notify applications of changes by leveraging the change capture and propagation features of Oracle Streams. See Oracle Database High Availability Best Practices. Figure 17-3 shows a simple architecture for a data warehouse. A data warehouse environment includes several tools in addition to a relational database. Oracle Flashback Technology is a family of human error correction features in Oracle Database. Submitted by NASA Administrator Sun, 2015-01-04 12:53. Data security is administered in the standard way, by granting and revoking privileges to Oracle Database users and roles.
