Oracle database (Oracle DB) is a relational database management system (RDBMS) from the Oracle Corporation. Originally developed in 1977 by Lawrence Ellison and other developers, Oracle DB is one of the most trusted and widely-used relational database engines.
The system is built around a relational database framework in which data objects may be directly accessed by users (or an application front end) through structured query language (SQL). Oracle is a fully scalable relational database architecture and is often used by global enterprises, which manage and process data across wide and local area networks. The Oracle database has its own network component to allow communications across networks. Oracle DB is also known as Oracle RDBMS and, sometimes, just Oracle.
Oracle DB runs on most major platforms, including Windows, UNIX, Linux and Mac OS. Different software versions are available, based on requirements and budget. Oracle DB editions are hierarchically broken down as follows:
• Enterprise Edition: Offers all features, including superior performance and security, and is the most robust
• Standard Edition: Contains base functionality for users that do not require Enterprise Edition's robust package
• Express Edition (XE): The lightweight, free and limited Windows and Linux edition
• Oracle Lite: For mobile devices
Microsoft SQL Server is an enterprise level relational database management system solution. It is Microsoft's high-end client/server database and is closely integrated with Microsoft Visual Studio and the Microsoft Office System. It is recommended when a robust database solution is required.
Microsoft SQL Server is offered as a "Fully Managed" database. In the Fully Managed infrastructure, IT owns, manages, and supports the Microsoft SQL Server hardware and software resources. The service includes high availability features and regular backups.
Fully Managed Microsoft SQL Server is recommended for departments, colleges, or other groups that require Microsoft SQL Server service but who do not have the appropriate hardware, software, or staff resources to run it themselves. It is also recommended for those who will be using Category-I data in their databases.
Microsoft SQL Server is a cloud-ready information platform that will help organizations unlock breakthrough insights across the organizations and quickly build solutions to extend data across on-premises and public cloud.
As the foundation of the cloud-ready information platform, SQL Server 2012 will help organizations unlock breakthrough insights across the organization as well as quickly build solutions and extend data across on-premises and public cloud backed by mission critical confidence.
MySQL is the world's most popular open source database, enabling the cost-effective delivery of reliable, high-performance and scalable Web-based and embedded database applications. MySQL runs under all popular operating systems. The free, open source versions are available under the GNU license, and hundreds of millions of copies have been downloaded worldwide.
The MySQL server provides a database management system with querying and connectivity capabilities, as well as the ability to have excellent data structure and integration with many different platforms. It can handle large databases reliably and quickly in high-demanding production environments. The MySQL server also provides rich function such as its connectivity, speed, and security that make it suitable for accessing databases.
The MySQL server works in a client and server system. This system includes a multiple-threaded SQL server that supports varied backends, different client programs and libraries, administrative tools, and manyapplication programming interfaces (API)s. It supports an extensive range of languages, since applications using MySQL are written in PHP, Perl, Python, Ruby, Java, C/C++, C# and Visual Basic. The MySQL programming interface (API) is a superset of the C language API for mSQL
