Oracle : An Introduction


ORACLE is a fourth generation relational database management system. In general, a database management system (DBMS) must be able to reliably manage a large amount of data in a multi-user environment so that many users can concurrently access the same data. All this must be accomplished while delivering high performance to the users of the database. A DBMS must also be secure from unauthorized access and provide efficient solutions for failure recovery. The ORACLE Server provides efficient and effective solutions for the major database features.

Oracle Capabilities

Oracle - Sending Email from an Application

    If you are running Oracle Application Express with Oracle Database 11g or later, you must enable outbound mail. Starting with Oracle Database 11g Release 1 (11.1), the ability to interact with network services is disabled by default. By default, the ability to interact with network services is disabled in Oracle Database 11g or later. Therefore, if you are running Oracle Application Express with Oracle Database 11g or later, you must use the DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the APEX_050000 database user.Failing to grant these privileges results in issues with:
  • Sending outbound mail in Oracle Application Express
  • Using Web services in Oracle Application Express
  • PDF/report printing

Oracle - Implementing Plug-ins

    Plug-ins enable developers to declaratively extend, share, and reuse the built-in types available with Oracle Application Express. Oracle Application Express supports a set group of authentication scheme, authorization scheme, item, region, dynamic action, and process types. Plug-ins offer a means of augmenting these built-in types by declaratively creating and using new types in your application. Because plug-ins are designed for reuse, developers can export and import them to other workspaces and also share them with the Oracle Application Express Plug-in community by using the Plug-in Repository.The process of implementing a plug-in involves the following steps:
  • Create a plug-in or import a plug-in into your application workspace
  • Edit or create an authorization scheme, item, region, process, or dynamic action type to use the plug-in
  • Run your application to test the plug-in

Benefits

  • Customer Satisfaction: One advantage of using Oracle databases is due to Oracles belief in customer satisfaction. For example, all Oracle databases are backward compatible. This allows businesses to upgrade their systems without a complete overhaul of their database system. This provides efficient and low-cost updates. In addition, new versions of Oracle databases provide new features while keep the popular features from older versions. This ensures that their product is based on the customer's function rather than what is cost-effective for Oracle.
  • Functionality: Oracle databases are used for practically all corporation level applications. Thus, Oracle databases dominate the banking industry. Ten of the world's top banks use Oracle databases to conduct their business. This is primarily due to Oracle's functionality.
  • Reliability: Another important advantage offered by Oracle databases are their reliability. Oracle is a database that delivers excellent performance when challenged with demanding tasks. The ACID test, which is an important tool used to ensure the integrity of data stored, was easily passed by Oracle databases. This test is important since reliable data storage is the main purpose of a database.
  • Flashback Technology: Oracle databases incorporate Flashback technology, which is a significant advantage. In the event of an application outage, due to any number of reasons, it is important not to lose data stored on a database system. Oracle's Flashback technology allows for efficient recovery of data incorrectly deleted or lost. Thus, Flashback technology essentially removes human error and increases database recovery time. In the end, this feature allows for a simplified management and administrative process.
  • The Oracle Database is perfectly used for all corporation level applications including Business, large enterprise, small size business etc.
  • It has capability to handle large amount of data without any single point of failure.
  • It also comes with an important tool called ACID which ensures the integrity of data which easily passed by the oracle databases.
  • The Oracle has capability to provide industrial strength support for online backup and recovery.
  • Oracle Database has many supporting tools like rman,sqlldr,oracle administrator manager which helps to improve the quality of product.

Oracle

Like other RDBMS software, Oracle Database is built on top of SQL, a standardized programming language that database administrators, data analysts and other IT professionals use to manage databases and query the data stored in them. The Oracle software is tied to PL/SQL, an implementation developed by Oracle that adds a set of proprietary programming extensions to standard SQL -- a common practice among RDBMS vendors. Oracle Database also supports programming in Java, and programs written in PL/SQL or Java can be called from the other language.

An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.

Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. With this architecture, each new system can be rapidly provisioned from the pool of components. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.

The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures.

  • Partitioning:

    Partitioning is powerful functionality that allows tables, indexes, and index-organized tables to be subdivided into smaller pieces, enabling these database objects to be managed and accessed at a finer level of granularity. Oracle provides a comprehensive range of partitioning schemes to address every business requirement. Moreover, since it is entirely transparent in SQL statements, partitioning can be used with any application, from packaged OLTP applications to data warehouses. Some advantages of partitioning are as follows:

    Increases performance:Increases performance by only working on the data that is relevant.

    Improves availability: Improves availability through individual partition manageability.

    Decreases costs: Decreases costs by storing data in the most appropriate manner.

    Easy as to implement: Is easy as to implement as it requires no changes to applications and queries.

    • Partitioning Methods:

      Range Partitioning: Range Partitioning The data is distributed based on a range of values.

      List Partitioning: List Partitioning The data distribution is defined by a discrete list of values. One or multiple columns can be used as partition key.

      Auto-List Partitioning: Auto-List Partitioning Extends the capabilities of the list method by automatically defining new partitions for any new partition key values.

      Hash Partitioning: Hash Partitioning An internal hash algorithm is applied to the partitioning key to determine the partition.

      Composite Partitioning: Composite Partitioning Combinations of two data distribution methods are used. First, the table is partitioned by data distribution method one and then each partition is further subdivided into subpartitions using the second data distribution method.

      Multi-Column Range Partitioning:Multi-Column Range Partitioning An option for when the partitioning key is composed of several columns and subsequent columns define a higher level of granularity than the preceding ones.

      Interval Partitioning: Interval Partitioning Extends the capabilites of the range method by automatically defining equi-partitioned ranges for any future partitions using an interval definition as part of the table metadata.

  • Real Application Clusters

    Oracle Real Application Clusters is an option to the award-winning Oracle Database Enterprise Edition. Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available database solutions for all business applications. Oracle RAC is a key component of Oracle's private cloud architecture.

SharePoint Server 2010 enables hands-off management of those solutions by automatically ensuring that those solutions stay within the predefined parameters of resource and CPU consumption.

  • Active Data Guard:

    Data Guard provides the management, monitoring, and automation software to create and maintain one or more synchronized copies of a production database to protect Oracle data from failures, disasters, human error, and data corruptions while providing high availability for mission critical applications. Data Guard is included with Oracle Database Enterprise Edition. The functionality includes:

    Real-Time Query: Real-Time Query offload read-only workloads to an up-to-date standby database.

    Automatic Block Repair: Automatic Block Repair automatic repair of physical corruption transparent to the user.

    Far Sync: Far Sync zero data loss protection across any distance.

    Standby Block Change Tracking:Standby Block Change Tracking enable incremental backups on an active standby

  • Advanced Analytics

    Oracle Advanced Analytics 12c delivers parallelized in-database implementations of data mining algorithms and integration with open source R. Data analysts use Oracle Data Miner GUI and R to build and evaluate predictive models and leverage R packages and graphs. Application developers deploy Oracle Advanced Analytics models using SQL data mining functions and R. With the Oracle Advanced Analytics option, Oracle extends the Oracle Database to an sclable analytical platform that mines more data and data types, eliminates data movement, and preserves security to anticipate customer behavior, detect patterns, and deliver actionable insights. Oracle Big Data SQL adds new big data sources and Oracle R Advanced Analytics for Hadoop provides algorithms that run on Hadoop.

  • Advanced Compression:

    Oracle Advanced Compression provides a comprehensive set of compression capabilities to help improve performance and reduce storage costs. It allows organizations to reduce their overall database storage footprint by enabling compression for all types of data: relational (table), unstructured (file), index, network, Data Guard Redo and backup data. Although storage cost savings and optimization across servers (production, development, QA, test, backup and etc...) are often seen as the most tangible benefits, additional innovative technologies included in Oracle Advanced Compression are designed to improve performance and to reduce CapEx and OpEx costs for all components of an IT infrastructure, including memory and network bandwidth as well as heating, cooling and floor-space costs.

  • Database In-Memory:

    Oracle Database In-Memory provides a unique dual-format architecture that enables tables to be simultaneously represented in memory using traditional row format and a new in-memory column format. The Oracle SQL Optimizer automatically routes analytic queries to the column format and OLTP queries to the row format, transparently delivering best-of-both-worlds performance. Oracle Database automatically maintains full transactional consistency between the row and the column formats, just as it maintains consistency between tables and indexes today. The new column format is a pure in-memory format and is not persistent on disk, so there are no additional storage costs or storage synchronization issues.
