Oracle database

The Oracle database is an application developed by the Oracle Corporation. It is an application known as an RDBMS which stands for Object-relational database management system. The main function of this application is for the storage and retrieval of related information. This application allows users to control concurrency or accessing similar data so that they cannot be changed or updated in such a way that would compromise the integrity of the data. This software also features read consistency which guarantees that there is consistency to a set of data within a statement and that the data cannot just be changed even if a statement is being executed. And with this application’s locking mechanism, the access of data can already be controlled so no one can make changes to it. This software is very useful for business organizations and offices requiring reliable software to manage their database information. This software is mainly associated with MSB files and runs on Windows, MAC, and Linux operating systems.

Microsoft SQL Server (2008)

SQL Server 2008, formerly codenamed Katmai, was released on August 6, 2008 and goals to make data self organizing, management self-tuning, and self maintaining with the improvement of SQL Server Always On technologies, to give almost-zero downtime. SQL Server 2008 also includes support for structured and semi-structured data, as well as digital media formats for pictures, audio, video and other multimedia data. In present versions, such multimedia data can be saved as BLOBs (binary large objects), but they are generic bit streams. It also natively supports hierarchical data, and includes T-SQL constructs to directly deal with them, without using recursive queries. Basic awareness of multimedia data will permit specialized functions to be performed on them. According to Paul Flessner, senior Vice President, Server Applications, Microsoft Corp., SQL Server 2008 can be a data storage backend for different varieties of data: XML, email, time/calendar, file, document, spatial, etc as well as perform search, query, analysis, sharing, and synchronization across all data types.

Microsoft SQL Server (2005)

SQL Server 2005, formerly codenamed Yukon, was released in October 2005. It’s a built-in native support for managing XML data and adding relational data. Purposely, it defined an XML data type that could be utilized either as literals in queries a data type or in database columns. XML columns can be linked with XSD schemas; XML data being saved is verified against the schema. XML is changed to an internal binary data type before being saved in the database. Specialized indexing methods were made available for XML data. XML data is inquired using XQuery; SQL Server 2005 added some extensions to the T-SQL language to permit embedding XQuery queries in T-SQL. In addition, it also defines a new extension to XQuery, called XML DML that allows query-based modifications to XML data. SQL Server 2005 also allows a database server to be exposed over Web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests. When the data is viewed over Web services, results are returned as XML.
