Business intelligence is the analysis of an organization's information as an aid to making business decisions. Oracle RAC supports services that can group database workloads and route work to the optimal instances assigned to offer the services. This database is a fully functional Oracle database that has a read-only copy of the relevant application tables. 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. A central database, or hub, communicates with secondary databases, or spokes. Maintaining one or more standby databases in a Data Guard environment enables you to provide continuous database service if the production site fails. Distributed SQL synchronously accesses and updates data distributed among multiple databases. You have to write a successful dissertation for this to happen. 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. Browse free Contemporary information technology research project topics and materials in Nigeria. The system to which a user is directly connected is called the local system. Oracle Database accomplishes this task by changing (redefining) database objects in a private environment known as an edition. Examples of computers failures include hardware and operating system failures. See Oracle Database Performance Tuning Guide for information on fast start fault recovery.

Replicating data between different platforms and Oracle Database releases, and across a wide area network (WAN). For example, it does not prevent directly connected, privileged users from performing inference attacks on redacted data. These sites typically only connect once a day to upload their orders and download any changes made after their last refresh. 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"). See Oracle Database Administrator's Guide to learn about transportable tablespaces. The queues can reside in the same or different databases. Oracle Database uses a noncentralized policy to free and acquire memory in each subcomponent of the SGA and the PGA. Oracle Database has introduced many SQL operations for performing analytic operations. You can assign a profile to one set of users, and a default profile to all others. For example, a volume manager error causes bad disk read or writes. These features include: Oracle Streams Advanced Queuing offers several ways to enqueue messages. Figure 17-3 shows both the metadata and raw data of a traditional OLTP system and summary data. Data corruptions are rare but can have a catastrophic effect on a database, and therefore a business. 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. Uses denormalized or partially denormalized schemas (such as a star schema) to optimize query performance. The primary objective of these changes is to improve performance, manageability, and functionality. D 0 is the initial instance of the database, 3. Oracle Database minimizes downtime for data changes through online reorganization and redefinition.

A staging area simplifies the tasks of building summaries and managing the warehouse. Figure 17-9 illustrates this Streams configuration. Administrators should grant privileges to users so they can accomplish tasks required for their jobs. Fault tolerance is the protection provided by a high availability architecture against the failure of a component in the architecture. The previous parts of this manual described the basic architecture of Oracle Database. Oracle LogMiner is a relational tool that enables online files to be read, analyzed, and interpreted using SQL (see "Oracle LogMiner"). A database link is a connection between two physical databases that enables a client to access them as one logical database. You define and apply business policies to these services to perform tasks such as to allocate nodes for times of peak processing or to automatically handle a server failure. Note: These slides are available for students and instructors in PDF and some slides also in postscript format.Slides in Microsoft Powerpoint format are available only for instructors.All slides except the slides for Chapter 24 are available now. Alternatively, you can use fine-grained auditing to monitor specific database activities, such as actions on a database table or times that activities occur. Business intelligence is the analysis of an organization's information as an aid to making business decisions. Oracle RAC supports services that can group database workloads and route work to the optimal instances assigned to offer the services. This database is a fully functional Oracle database that has a read-only copy of the relevant application tables. 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. A central database, or hub, communicates with secondary databases, or spokes. Maintaining one or more standby databases in a Data Guard environment enables you to provide continuous database service if the production site fails. Distributed SQL synchronously accesses and updates data distributed among multiple databases. You have to write a successful dissertation for this to happen. 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. Browse free Contemporary information technology research project topics and materials in Nigeria. The system to which a user is directly connected is called the local system. Oracle Database accomplishes this task by changing (redefining) database objects in a private environment known as an edition. Examples of computers failures include hardware and operating system failures. See Oracle Database Performance Tuning Guide for information on fast start fault recovery. 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. One rule could calculate the sales of a product in 2011 as the sum of sales in 2009 and 2010. Oracle ASM is a vertically integrated file system and volume manager in the database kernel (see "Oracle Automatic Storage Management (Oracle ASM)"). For example, an OLTP database used by an online bookseller is available to the extent that it is accessible by customers making purchases. At the heart of any integration is the sharing of data among applications in the enterprise. If the environment uses a real-time standby database, then RMAN can automatically repair corrupt blocks. Running and Developing Tests with the Apache::Test Framework webhostingguy.

However, each server has additional processes that communicate with each other so that separate servers work together as if they were one server. A summary is an aggregate view that improves query performance by precalculating expensive joins and aggregation operations and storing the results in a table. Several database components and utilities, including RMAN, can detect a corrupt block and record it in V$DATABASE_BLOCK_CORRUPTION. 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. The changes made to replicated database objects at one database are captured and sent directly to the other database, where they are applied. Data warehouses and OLTP database have different requirements. We return to the connection overview and see that the new sql connection was added. A block corruption is a data block that is not in a recognized Oracle format, or whose contents are not internally consistent. Providing load balancing and improved scalability and availability for a call center or similar application.

Profiles provide a single point of reference for users that share a set of attributes. End users of a data warehouse do not directly update the database. Oracle Database is not itself an ETL tool. Oracle Database provides many techniques to control access to data. When a user attempts to access data, OLS compares the user label with the data label and determines whether access should be granted. Availability is the degree to which an application, service, or functionality is available on demand. 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"). It is 1000+ papers database. Oracle Database Vault is a security option that restricts privileged user access to application data. For example, Enterprise Manager enables you to display and search for the properties of current audited statements, privileges, and objects. You can use regular expressions for both full and partial redaction. Oracle Database provides multiple tools and techniques for monitoring user activity. See Oracle Database Data Warehousing Guide to learn about aggregation. A service represents the workload of applications with common attributes, performance thresholds, and priorities. Transportable tablespaces are the fastest way for moving large volumes of data between two Oracle databases. They must resolve such problems as naming conflicts and inconsistencies among units of measure. Many applications are integrated with a distributed hub and spoke model with Oracle Database as the hub. ... 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 You can incrementally add nodes to a cluster instead of replacing existing systems with larger nodes. The dilemma about the topic selection gets aggravated further when a guide demands the selection of a … The following example adds a full data redaction policy to redact the employee_id column of the hr.employees table: In the preceding example, the expression setting, which evaluates to true, applies the redaction to users who are not granted the EXEMPT REDACTION POLICY privilege. Looks like you’ve clipped this slide to already. These operations require SYSDBA or SYSOPER privileges (see "Connection with Administrator Privileges"). A role is a named group of related privileges that you grant to users or other roles. You will get an idea of various farming related presentation topics. CSE 736: Advanced Topics in Database Systems Spring 2010 Staff. See "Overview of Grid Computing". LCRs are placed in a staging area, which is a queue that stores and manages captured messages. However, this technique can be time-consuming, and the backup may not be current. Replication is the process of sharing database objects and data at multiple databases. Figure 17-2 illustrates the Database Server Grid and Database Storage Grid in a Grid enterprise computing environment. The Cache Fusion technology implemented in Oracle RAC enables you to scale capacity without changing your applications. Subject to individual DML statements routinely issued by end users.

The reporting site is not configured to capture changes on these application tables. Top 18 Database Projects Ideas for Students If you need someone who can do your database project, Check my SQL homework help. Oracle Streams Advanced Queuing supports industry-standard APIs: SQL, JMS, and SOAP. Thus, after data has entered into the warehouse, data should not change. Regarding video, this particular presentation wasn’t recorded but if you go through the presentation and still have any specific question just come back here and post it. Data redaction supports the following redaction function types: In this case, the database redacts the entire contents of the specified columns in a table or view. You can use Oracle Database Vault to control when, where, and how the databases, data, and applications are accessed. 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. Grid Plug and Play also enables databases and services to be managed in a location-independent manner. Oracle Flashback Technology is a family of human error correction features in Oracle Database. You can tailor auditing and monitoring controls to meet enterprise security requirements. You can enable and disable auditing as needed. Oracle Streams Concepts and Administration, Oracle Streams Replication Administrator's Guide. This is the right to perform a specific action on an object, for example, query the employees table. In this case, the database displays the data as randomly generated values, depending on the data type of the column. This infrastructure enables the propagation and management of data, transactions, and events in a data stream either within a database, or from one database to another. Enqueuing is the process by which producers place messages into queues. 14 Outstanding Sport Management Dissertation Topics. 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").

Oracle Flashback provides a SQL interface to quickly analyze and repair human errors. Ideas for Research Paper Topics The purpose of the seminar is to present and discuss the state-of-the-art on a set of topics in current database research. An apply process implicitly applies changes encapsulated in LCRs. DDL commands require exclusive locks on internal structures (see "DDL Locks"). The simplest form of protection against site failures is to create database backups using RMAN and store them offsite. You can share information, which lets you maintain the information in multiple data stores and applications. 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. A data corruption occurs when a hardware, software or network component causes corrupt data to be read or written. The database contains several default accounts, including the default administrative account SYSTEM (see "SYS and SYSTEM Schemas"). See Oracle Database Data Warehousing Guide to learn about SQL for analysis and reporting. Oracle Database provides different authentication methods, including the following: Oracle database can authenticate users using a password, Kerberos ticket, or PKI certificate. In an Oracle RAC environment, Oracle Database runs on two or more systems in a cluster while concurrently accessing a single shared database. Data warehouses and their architectures vary depending on the business requirements. Validating the identity establishes a trust relationship for further interactions. Topics in Database Systems: Topic: Main Memory and Embedded DBMS CS 848, Waterloo, Spring '18 ... project presentation: 20-30 minutes in weeks 10-12(-13); report (in pdf, up to 10 pages), source code (if applicable) If you don't see any relation to your own research, here are a few alternative options. Replicating data between different platforms and Oracle Database releases, and across a wide area network (WAN). For example, it does not prevent directly connected, privileged users from performing inference attacks on redacted data. These sites typically only connect once a day to upload their orders and download any changes made after their last refresh. 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"). See Oracle Database Administrator's Guide to learn about transportable tablespaces. The queues can reside in the same or different databases. Oracle Database uses a noncentralized policy to free and acquire memory in each subcomponent of the SGA and the PGA. Oracle Database has introduced many SQL operations for performing analytic operations. You can assign a profile to one set of users, and a default profile to all others. For example, a volume manager error causes bad disk read or writes. These features include: Oracle Streams Advanced Queuing offers several ways to enqueue messages. Figure 17-3 shows both the metadata and raw data of a traditional OLTP system and summary data. Data corruptions are rare but can have a catastrophic effect on a database, and therefore a business. 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. Uses denormalized or partially denormalized schemas (such as a star schema) to optimize query performance. The primary objective of these changes is to improve performance, manageability, and functionality. D 0 is the initial instance of the database, 3. Oracle Database minimizes downtime for data changes through online reorganization and redefinition. In the extreme case, an Oracle RAC system provides database service even when all but one node is down. Unlike VPD, OLS provides an out-of-the-box security policy and the metadata repository for defining and storing labels. D … 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. Designed to accommodate ad hoc queries. In general, database access control involves restricting data access and database activities. Because the physical nodes run independently, the failure of one or more nodes does not affect other nodes in the cluster.
