Oracle Database 2 Day + Data Replication and Integration Guide to learn how to send messages using Advanced Queuing, Oracle Streams Advanced Queuing User's Guide. For example, a user may retrieve the current order for a single customer. Data redaction is not a comprehensive security solution. Oracle Database has introduced many SQL operations for performing analytic operations. Changes are formatted into logical change records (LCRs), which are messages with a specific format describing a database change. In general, database security involves user authentication, encryption, access control, and monitoring. Oracle Database autotunes memory by prompting the operating system to transfer granules of memory to components that require it. 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. Each server looks like any standalone server. These operations include ranking, moving averages, cumulative sums, ratio-to-reports, and period-over-period comparisons. This section focuses on Oracle solutions for federating and sharing information. For example, the clerk profile could limit a user to system resources required for clerical tasks. The reporting site is not configured to capture changes on these application tables. In this case, it is important to design a system to minimize planned interruptions such as routine operations, periodic maintenance, and new deployments. If the environment uses a real-time standby database, then RMAN can automatically repair corrupt blocks. VPD is useful when security protections such as privileges and roles are not sufficiently fine-grained. If you continue browsing the site, you agree to the use of cookies on this website. Section 501 A site failure may affect all processing at a data center, or a subset of applications supported by a data center. This will help students, teachers, academicians, parents, and researchers. Additionally, ASM automatically redistributes data as disks from storage arrays are added or removed from the Database Storage Grid. The employees synonym hides the identity and location of the remote schema object. File Upload webhostingguy. The application role ACCTS_PAY, which includes the privilege to execute the ACCTS_PAY application, is assigned to users with the PAY_CLERK and MANAGER role. End users directly access data that was transported from several source systems to the data warehouse. An example is an application upgrade. The Table Topics Database Search Table Topic questions for Toastmasters meetings Search our database for fun and engaging Table Topics for practice or your next Toastmasters meeting. Oracle Data Mining supports a PL/SQL API, a Java API, SQL functions for model scoring, and a GUI called Oracle Data Miner. Thus, you can address common security problems such as protecting against insider threats, complying with regulatory requirements, and enforcing separation of duty. You can use standard auditing to audit SQL statements, privileges, schemas, objects, and network and multitier activity. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations. Examples include table redefinition, adding table partitions, and creating or rebuilding indexes. The presentation goes on to answer the question of the title slide with a series of predictions about the future. Propagations can send messages from one queue to another. For example, these analytic functions enable you to calculate rankings and percentiles and moving windows. 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. See Oracle Database High Availability Overview. Oracle OLAP User's Guide for an overview of Oracle OLAP. Figure 17-5 separates purchasing, sales, and inventory information into independent data marts. Unlike VPD, OLS provides an out-of-the-box security policy and the metadata repository for defining and storing labels. Top 18 Database Projects Ideas for Students If you need someone who can do your database project, Check my SQL homework help. It includes support for scalar data types, Oracle Database object types with inheritance, XMLType with additional operators for XML data, and ANYDATA. Oracle has advanced SQL analytical processing capabilities using a family of analytic SQL functions. Transparent data encryption includes industry-standard encryption algorithms such as the Advanced Encryption Standard (AES) and built-in key management. Cubes and other dimensional objects are first class data objects represented in the Oracle data dictionary. In the policy, specify a predefined redaction function. Oracle Clusterware provides all of the features required to run the cluster, including node membership and messaging services. A financial analyst can query the data marts for historical information about purchases and sales. Messaging is the sharing of information between applications and users. In this way, the database objects and data are kept synchronized at all databases in the replication environment. If you continue browsing the site, you agree to the use of cookies on this website. 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. To improve aggregation performance in a warehouse, the database provides extensions to the GROUP BY clause to make querying and reporting easier and faster. A common way of introducing data warehousing is to refer to the characteristics of a data warehouse as set forth by William InmonFoot 1 : Data warehouses enable you to define a database by subject matter, such as sales. 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. Oracle ASM is a vertically integrated file system and volume manager in the database kernel (see "Oracle Automatic Storage Management (Oracle ASM)"). After being authenticated by the operating system, users can connect to a database without specifying a user name or password. For example, you can audit a table accessed after 9:00 p.m. For example, Oracle Streams propagates an update to an employees table to an identical employees table in a different database. The reporting database is hosted in New York. 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. Database management system or DBMS is used to maintain data and provide different solutions for managing data in different applications. PRESENTATION OF TOPICS IIB THESES ASSIGNMENT , DECEMBER 11TH, 2020 2. A key advantage of the Oracle RAC architecture is the inherent fault tolerance provided by multiple nodes. ASM partitions the disk space and evenly distributes the data across the disks provided to ASM. For example, an OLTP database used by an online bookseller is available to the extent that it is accessible by customers making purchases. You can share information, which lets you maintain the information in multiple data stores and applications. 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. Enqueuing is the process by which producers place messages into queues. The roles PAY_CLERK, MANAGER, and REC_CLERK are assigned to different users. After being enqueued, messages can be transformed and propagated before being dequeued to the partner's application. Oracle Streams includes replication and messaging. _____ 7. Analytic functions compute an aggregate value based on a group of rows. Oracle Database Advanced Security Administrator's Guide to learn about data redaction, Oracle Database PL/SQL Packages and Types Reference to learn about DBMS_REDACT. Oracle Database High Availability Overview for an overview of Grid Computing, http://www.gridforum.org/ to learn about the standards organization Global Grid Forum (GGF). 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. In a hub-and-spoke replication environment, the spokes might or might not allow changes to the replicated database objects. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Encrypting data on the network prevents this sort of activity. The OLAP engine runs within the kernel of Oracle Database. 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. Slides for Database Management Systems, Third Edition. 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. Each Oracle database has a list of valid database users. LCRs are placed in a staging area, which is a queue that stores and manages captured messages. For example, it does not prevent directly connected, privileged users from performing inference attacks on redacted data. 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. They can also notify applications of changes by leveraging the change capture and propagation features of Oracle Streams. Take a look at these great reusable presentation templates created by members of the Prezi community. Replication is the process of sharing database objects and data at multiple databases. For example, to discover trends in business, data warehouses must maintain large amounts of data. DDL specified with the WAIT option resolves this issue. You can incrementally add nodes to a cluster instead of replacing existing systems with larger nodes. Share yours for free! Oracle Streams Concepts and Administration, Oracle Streams Replication Administrator's Guide. In addition, Oracle Scheduler jobs can run using a service, as opposed to using a specific instance. Typical applications of data mining include call centers, ATMs, E-business relational management (ERM), and business planning. The credential may be a password, Kerberos ticket, or public key infrastructure (PKI) certificate. Some students lack the skill to write good topics for PowerPoint presentation. Rules determine which changes are captured. Browse free Contemporary information technology research project topics and materials in Nigeria. Good Design Makes a Difference. End users of a data warehouse do not directly update the database. The changes made to replicated database objects at one database are captured and sent directly to the other database, where they are applied. Uses fully normalized schemas to optimize DML performance and to guarantee data consistency. Oracle Streams is the asynchronous information sharing infrastructure in Oracle Database. You can enable and disable auditing as needed. Business intelligence and analytical applications are dominated by actions such as drilling up and down hierarchies and comparing aggregate values. In an Oracle RAC environment, Oracle Database runs on two or more systems in a cluster while concurrently accessing a single shared database. Figure 17-7 depicts the basic information flow in a replication environment. This is the right to perform a specific action on an object, for example, query the employees table. The foundation of federated access is a distributed environment, which is a network of disparate systems that seamlessly communicate with each other. A staging area simplifies the tasks of building summaries and managing the warehouse. Figure 17-5 Architecture of a Data Warehouse with a Staging Area and Data Marts. I will notify all students via e-mail when this webpage is updated and I … They must resolve such problems as naming conflicts and inconsistencies among units of measure. Data based management main purpose is to store and retrieve data for large and small bodies of information. Get ideas for your own presentations. The primary objective of these changes is to improve performance or manageability. For example, standard DML statements work just as they do in a non-distributed database environment. 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. 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. Aggregation is fundamental to data warehousing. Oracle LogMiner is a relational tool that enables online files to be read, analyzed, and interpreted using SQL (see "Oracle LogMiner"). 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. When an order is entered, the business uses AQ to send the order ID and order date to a database in a warehouse. Depending on the method of transportation, some transformations can occur during this process. Oracle online analytical processing (OLAP) provides native multidimensional storage and rapid response times when analyzing data across multiple dimensions. The application role ACCTS_REC, which includes the privilege to execute the ACCTS_REC application, is assigned to users with the REC_CLERK and MANAGER role. The Oracle distributed database architecture provides query and transaction transparency. Grid Plug and Play simplifies addition and removal of nodes from a cluster, making it easier to deploy clusters in a dynamically provisioned environment. See Oracle Database High Availability Best Practices. With Oracle Data Mining, the data, data preparation, model building, and model scoring results all remain in the database. Stores many months or years of data to support historical analysis. Data Guard enables you to maintain a copy of a production database, called a standby database, that can reside on a different continent or in the same data center. Distributed SQL includes distributed queries and distributed transactions. Hi Dawood, you can see the presentation in the embedded prezi window in the post. 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. The script content on this page is for navigation purposes only and does not alter the content in any way. Whether the database shows the actual or redacted value of a column depends on the policy. A summary is an aggregate view that improves query performance by precalculating expensive joins and aggregation operations and storing the results in a table. A security policy establishes methods for protecting a database from accidental or malicious destruction of data or damage to the database infrastructure. Figure 17-2 illustrates the Database Server Grid and Database Storage Grid in a Grid enterprise computing environment. Database auditing is the monitoring and recording of selected user database actions. Dr. Michalis Petropoulos, Assistant Professor ; Description. 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. Streams can also be used to exchange data for particular tables with non-Oracle databases. 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. 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. Validating the identity establishes a trust relationship for further interactions. 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. A data corruption occurs when a hardware, software or network component causes corrupt data to be read or written. A role helps manage privileges for a database application or user group. ETL refers to a broad process rather than three well-defined steps. Replicating data between different platforms and Oracle Database releases, and across a wide area network (WAN). A service represents the workload of applications with common attributes, performance thresholds, and priorities. 4. 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. For example, you can allow all users to access the employees table, but create security policies to restrict access to employees in the same department as the user. Grid Plug and Play also enables databases and services to be managed in a location-independent manner. Transportable tablespaces are the fastest way for moving large volumes of data between two Oracle databases. Maintaining one or more standby databases in a Data Guard environment enables you to provide continuous database service if the production site fails. However, each server has additional processes that communicate with each other so that separate servers work together as if they were one server. You can tailor auditing and monitoring controls to meet enterprise security requirements. 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. 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. A common cause of unplanned downtime is a system fault or crash. Encrypting data as it travels across a network between a client and server is known as network encryption. Each system in the environment is called a node. The fast start fault recovery technology in Oracle Database automatically bounds database instance recovery time. A single database system spans multiple hardware systems yet appears to the application as a single database. When a user attempts to access data, OLS compares the user label with the data label and determines whether access should be granted. A typical operation accesses only a handful of records. Figure 17-3 shows a simple architecture for a data warehouse. Changes made using SQL are captured automatically as messages. This database is a fully functional Oracle database that has a read-only copy of the relevant application tables. However, the following types of replication environments are the most common: Only two databases share the replicated database objects. For example, you can restrict users from querying specified tables or executing specified database commands. 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. 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. Supports only predefined operations. Fault tolerance is the protection provided by a high availability architecture against the failure of a component in the architecture. See Oracle Automatic Storage Management Administrator's Guide to learn more about Oracle ASM. The WHERE clause allows only users whose credentials pass the security policy to access the protected data. DataBase Intellegence Presentation Alexandr Zhuravlev. You can create user accounts as needed. To access a database, a user must provide a valid user name and authentication credential. With the MODEL clause, you can create a multidimensional array from query results and apply rules to this array to calculate new values. Lost write detection is most effective when used with Data Guard. See Oracle Database Data Warehousing Guide to learn about table functions. Oracle Enterprise Manager (Enterprise Manager) enables you to view and configure audit-related initialization parameters. A SQL grammar-based engine monitors and blocks unauthorized SQL traffic before it reaches the database. See Oracle Database Advanced Application Developer's Guide. It has a nifty auto save feature that saves your progress for you, so you can litereally log out, walk away, and not worry about a thing. The redaction occurs in real time when users query the data. 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. Figure 17-9 illustrates this Streams configuration. LCRs remain in a staging area until subscribers consume them implicitly or explicitly. Figure 17-4 shows a data warehouse with a staging area, which is a place where data is preprocessed before entering the warehouse. Message staging provides a holding area with security, as well as auditing and tracking of message data. See our User Agreement and Privacy Policy. You can achieve this goal by transporting data in the warehouse to data marts, which are independent databases designed for a specific business or project. See "Memory Management". The primary objective of these changes is to improve performance, manageability, and functionality. The purpose of the seminar is to present and discuss the state-of-the-art on a set of topics in current database research. Ideas for Research Paper Topics A good design should enhance a presentation, not distract from it. The system to which a user is directly connected is called the local system. 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"). Oracle Flashback Technology is a family of human error correction features in Oracle Database. A local user can access a link to a remote database without being a user on the remote database. Oracle Database provides dynamic resource provisioning as a solution to planned system and database changes: Oracle Database dynamically accommodates various changes to hardware and database configurations, including adding and removing processors from an SMP server and adding and remove storage arrays using Oracle ASM.
