Dr. Michalis Petropoulos, Assistant Professor ; Description. Oracle Advanced Security Transparent Data Encryption enables you to encrypt individual table columns or a tablespace. Oracle Database accomplishes this task by changing (redefining) database objects in a private environment known as an edition. A DBA or storage administrator can use the Oracle ASM interface to specify the disks within the Database Storage Grid that ASM should manage across all server and storage platforms. Oracle RAC supports services that can group database workloads and route work to the optimal instances assigned to offer the services. Multiple applications share the same queue, eliminating the need to add queues to support additional applications. See Oracle Database Performance Tuning Guide for information on fast start fault recovery. The presentation goes on to answer the question of the title slide with a series of predictions about the future. Oracle Database High Availability Best Practices to learn how to recover from human errors, Oracle Database Backup and Recovery User's Guide and Oracle Database Advanced Application Developer's Guide to learn more about Oracle Flashback features, Oracle Database Utilities to learn more about Oracle LogMiner. Support for explicit dequeue allows developers to use Oracle Streams to reliably exchange messages. Ideas for Research Paper Topics Oracle Database provides powerful tools to help administrators quickly diagnose and recover from these errors. In general, encryption is the process of transforming data into an unreadable format using a secret key and an encryption algorithm. Figure 17-1 depicts a common use for roles. In this case, the database redacts portions of the displayed output. Oracle has advanced SQL analytical processing capabilities using a family of analytic SQL functions. Database auditing is the monitoring and recording of selected user database actions. See Oracle Database Data Warehousing Guide to learn about SQL for analysis and reporting. The data model in an ADF application consists of application modules, View objects, View object links, entities, and entity associations. D 0 is the initial instance of the database, 3. 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. Oracle Data Redaction is a part of Oracle Advanced Security. A database link is a connection between two physical databases that enables a client to access them as one logical database. In addition, Oracle Scheduler jobs can run using a service, as opposed to using a specific instance. Encrypting data on the network prevents this sort of activity. Presentation leadership & engineering mgmt. "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. Oracle Database 2 Day + Real Application Clusters Guide to learn about Oracle services, Oracle Database Administrator's Guide to learn about the Database Resource Manager and Oracle Scheduler. For example, Enterprise Manager enables you to display and search for the properties of current audited statements, privileges, and objects. For example, to discover trends in business, data warehouses must maintain large amounts of data. You can tailor auditing and monitoring controls to meet enterprise security requirements. Changes made at each database can be reflected at every other database, providing complete data for the subscribed objects throughout the world. To access a database, a user must provide a valid user name and authentication credential. Unlike VPD, OLS provides an out-of-the-box security policy and the metadata repository for defining and storing labels. It includes support for scalar data types, Oracle Database object types with inheritance, XMLType with additional operators for XML data, and ANYDATA. You will get an idea of various farming related presentation topics. 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. You may want to customize your warehouse architecture for different groups within your organization. Database, any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. Presentation on Database management system, Web Hosting - Site Builder - Domain Name Registration, Running and Developing Tests with the Apache::Test Framework, Load-balancing web servers Load-balancing web servers, No public clipboards found for this slide, Student at S.b jain college of engineering. See Oracle Database High Availability Best Practices. For example, an application can present a credit card number ending in 1234 as xxxx-xxxx-xxxx-1234. Each salesperson receives an updatable copy of the required portion of data. This database is a fully functional Oracle database that has a read-only copy of the relevant application tables. Data based management main purpose is to store and retrieve data for large and small bodies of information. Oracle ASM automates and simplifies the layout of data files, control files, and log files by automatically distributing them across all available disks. For example, standard DML statements work just as they do in a non-distributed database environment. A database is typically represented by a cylindrical diagram. Additionally, ASM automatically redistributes data as disks from storage arrays are added or removed from the Database Storage Grid. OND PROJECT MATERIALS │HND PROJECTS │BSC PROJECTS │MBA PROJECT THESIS POST GRADUATE DIPLOMA . Thus, you can scale the system incrementally to save costs and eliminate the need to replace smaller single-node systems with larger ones. At each regional database, an Oracle Streams apply process applies the changes automatically. Stores many months or years of data to support historical analysis. Data warehouses and OLTP database have different requirements. After being enqueued, messages can be transformed and propagated before being dequeued to the partner's application. This section focuses on Oracle solutions for federating and sharing information. See Oracle Database Administrator's Guide to learn about transportable tablespaces. Your applications might be specifically tuned or designed to support only these operations. Oracle OLAP has the following primary characteristics: Oracle OLAP is integrated in the database so that you can use standard SQL administrative, querying, and reporting tools. Subject to individual DML statements routinely issued by end users. Data redaction is not a comprehensive security solution. Clipping is a handy way to collect important slides you want to go back to later. You can share information, which lets you maintain the information in multiple data stores and applications. Andreia Durães. You can restore the database to another host. Thus, after data has entered into the warehouse, data should not change. Profiles provide a single point of reference for users that share a set of attributes. If that’s not working for you, there’s also the direct link in the post as well. See Oracle Database Upgrade Guide. Oracle RAC integrates the listener with Oracle Clients and the connection pools to create optimal application throughput. In a Database Server Grid, Oracle RAC enables you to add nodes to the cluster as the demand for capacity increases. Business intelligence is the analysis of an organization's information as an aid to making business decisions. Whether the database shows the actual or redacted value of a column depends on the policy. In the architecture shown in Figure 17-3, operational data must be cleaned and processed before being put into the warehouse. See "Memory Management". They can also notify applications of changes by leveraging the change capture and propagation features of Oracle Streams. Message staging provides a holding area with security, as well as auditing and tracking of message data. Oracle Streams is the asynchronous information sharing infrastructure in Oracle Database. Transportable tablespaces are the fastest way for moving large volumes of data between two Oracle databases. Using services ensures the application of system resources where and when they are needed to achieve business goals. Oracle Database has introduced many SQL operations for performing analytic operations. The primary objective of these changes is to improve performance or manageability. Induction Variables and Reduction in Strength . Oracle ASM eliminates the complexity associated with managing data and disks, and simplifies mirroring and the process of adding and removing disks. 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. Many are downloadable. 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. To reduce disk use and memory use, you can store tables and partitioned tables in a compressed format (see "Table Compression"). This is the right to perform a specific action on an object, for example, query the employees table. Examples include table redefinition, adding table partitions, and creating or rebuilding indexes. A history over a database schema ρ and a data domain D is a sequence H = (D 0, …, D n) of database instances (called states) such that 1. all the states D 0, …, D n share the same schema ρ and the same data domain D, 2. Oracle Database uses a noncentralized policy to free and acquire memory in each subcomponent of the SGA and the PGA. Grid computing is a computing architecture that effectively pools large numbers of servers and storage into a flexible, on-demand resource for all enterprise computing needs. Oracle Database autotunes memory by prompting the operating system to transfer granules of memory to components that require it. Click the Rename button to change the description and click Enter.Then click the Add Query button to continue the creation of our SQL presentation.. We get a list of tables and views that are declared on the database. This will help students, teachers, academicians, parents, and researchers. As an organization evolves, it becomes increasingly important for it to be able to share information among multiple databases and applications. Availability is the degree to which an application, service, or functionality is available on demand. 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. The fast start fault recovery technology in Oracle Database automatically bounds database instance recovery time. These operations include ranking, moving averages, cumulative sums, ratio-to-reports, and period-over-period comparisons. Uses fully normalized schemas to optimize DML performance and to guarantee data consistency. 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. Several database components and utilities, including RMAN, can detect a corrupt block and record it in V$DATABASE_BLOCK_CORRUPTION. The dilemma about the topic selection gets aggravated further when a guide demands the selection of a … For example, rows that contain highly sensitive data can be labeled HIGHLY SENSITIVE, while rows that are less sensitive can be labeled SENSITIVE, and so on. These operations require SYSDBA or SYSOPER privileges (see "Connection with Administrator Privileges"). The reporting site is not configured to capture changes on these application tables. The changes made to replicated database objects at one database are captured and sent directly to the other database, where they are applied. After being authenticated by the operating system, users can connect to a database without specifying a user name or password. A good design should enhance a presentation, not distract from it. Automated distributions of data files, control files, and online redo log files. Proper citation depends on your preferred or required style manual. Analytic functions compute an aggregate value based on a group of rows. Data corruptions are rare but can have a catastrophic effect on a database, and therefore a business. Visit Edusson Samples to brainstorm possible research paper topics and find relevant paper examples. See Oracle Database Data Warehousing Guide to learn about SQL modeling. For example, the number 1234567 can appear as 83933895. Stores data from only a few weeks or months. Historical data retained as needed to meet the requirements of the current transaction. See Oracle Data Guard Concepts and Administration. These messages alert employees at the warehouse about the orders so that they can fill and ship them. You can dynamically allocate and deallocate these resources based on business priorities. 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. 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. In a typical scenario, data from one or more operational systems is extracted and then physically transported to the target system or an intermediate system for processing. Share yours for free! 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. The changes made to replicated database objects at one database are captured and sent directly to each of the other databases in the environment, where they are applied. 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. Services are integrated with the Database Resource Manager, which enables you to restrict the resources that are used by a service within an instance. These sites typically only connect once a day to upload their orders and download any changes made after their last refresh. When users select the column, the data is decrypted. Figure 17-3 shows both the metadata and raw data of a traditional OLTP system and summary data. 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. 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. If you continue browsing the site, you agree to the use of cookies on this website. Figure 17-4 Architecture of a Data Warehouse with a Staging Area. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The OLAP engine runs within the kernel of Oracle Database. CSE 736: Advanced Topics in Database Systems Spring 2010 Staff. Oracle Streams includes replication and messaging. For a sample use case, assume that a company uses Oracle Streams to maintain multiple copies of a corporate Web site. Transforming and consolidating data from multiple locations. When a user inserts data into an encrypted column, the database automatically encrypts the data. 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"). 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. An Oracle distributed database system can be transparent to users, making it appear as a single Oracle database. In a bi-directional replication environment, both databases can allow changes to the replicated objects. Typically, data marts include many summary tables.
