About Database Oracle and SQL Serve

Oracle Database:

Oracle Database, also known as Oracle RDBMS, or Oracle. is a relational database management system of Oracle Corporation. It is a leading product in the field of database. It can be said that Oracle database system is currently the world's popular relational database management system, System portability, easy to use, strong function, applicable to all kinds of large, medium, small, microcomputer environment. It is a highly efficient and reliable database solution that adapts to high throughput.

SQL Server:

SQL Server generally refers to Microsoft SQL Server

SQL Server is a relational database management system launched by Microsoft Corporation. With ease of use scalability and the high degree of integration of related software, you can span multiple platforms, from laptops running Microsoft Windows 98 to large multiprocessor servers running Microsoft Windows 2012. Microsoft SQL Server is a comprehensive database platform that provides enterprise-class data management with integrated Business Intelligence (BI) tools. The Microsoft SQL Server Database engine provides more secure and reliable storage capabilities for relational and structured data, enabling you to build and manage high-availability and high-performance data applications for your business.

The difference between Oracle and SQL Server:

 　　 First, openness
1, SQL Server can only run on Windows, without the slightest openness, the stability of the operating system is very important to the database. The Windows9x series is focused on desktop applications, and NT server is only suitable for small and midsize businesses. And the reliability, security and scalability of the Windows platform are very limited. It is not as proven as UNIX, especially when dealing with large databases.
2. Oracle can run on all major platforms (including Windows). Full support for all industry standards. Adopt a fully open strategy. Enables customers to choose the solution that best suits them. Full support to developers.
 　　 second, scalability, parallelism
1, SQL Server parallel implementation and coexistence model is immature, it is difficult to handle the increasing number of users and data volumes, scalability is limited.
2. Oracle Parallel server expands WINDOWNT's capabilities by enabling a set of nodes to share work in the same cluster, providing a solution for high availability and highly scalable clusters. If the windowsnt does not meet the needs, the user can move the database to UNIX. Oracle's parallel servers have a fairly high level of integration into the clustering mechanisms of various UNIX platforms.
 　　 Third, Performance
1. Poor performance in SQL Server multi-user
2. Oracle has the highest performance, keeping the world record of tpc-d and Tpc-c under the open platform.
 　　 Iv. Client Support and Application Mode
1, SQL Server C/s structure, only support Windows customers, you can use ADO, DAO, OLE DB, ODBC connection.
2, Oracle Multi-level network computing, support a variety of industry standards, you can use ODBC, JDBC, OCI and other network customers connect.
 　　 five, easy to operate
1, SQL Server operation is simple, but only the graphical interface.
2, Oracle is more complex, while providing GUI and command line, the same operation under WindowsNT and UNIX.
 　　 vi. risk of Use
1, SQL Server completely rewrite the code, experienced long-term testing, continuous delay, many functions need time to prove. is not very compatible.
2, Oracle long-time development experience, completely backwards compatible. are widely used. There is no risk at all. The final price of Oracle over Sqlsrver.
