Advantages of Oracle over sqlserver

Compare Oracle and MSSQL. The main differences and advantages of server. What are the differences in specific use?

 

 

Openness:

SQL Server can only run on windows without any openness. The stability of the operating system is very important to the database. The Windows9x series products focus on desktop applications, and the NT Server is only suitable for small and medium enterprises. In addition, the reliability, security, and scalability of the Windows platform are very limited. It is not as tested as UNIX, especially when dealing with key businesses with large data volumes.

Oracle can run on all major platforms (including windows ). Fully supports all industrial standards. Adopt a fully open policy. Customers can select the most suitable solution. Provide full support to developers.

DB2 can run on all major platforms (including windows ). It is most suitable for massive data volumes. DB2 is the most widely used in enterprise-level applications. Of the 500 largest enterprises in the world, almost 85% of them use DB2 database servers, and about 5% in China to 97 years.

Scalability and concurrency

The SQL Server DB2 parallel implementation and coexistence model is not mature. It is difficult to process the increasing number of users and data volumes. Limited scalability.

The Oracle Parallel server enables a group of nodes to share the work of the same cluster to expand the capabilities of the mongonets, providing high availability and high scalability cluster solutions. If WindowsNT cannot meet your needs, you can move the database to Unix.

DB2 DB2 has good concurrency. DB2 expands database management to a parallel, multi-node environment. Database partitions are a part of the database, including its own data, indexes, configuration files, and transaction logs. Database partitions are sometimes called nodes or database nodes.

Security

SQL Server does not receive any security certificate.

Oracle server receives the highest level of ISO certification.

DB2 has obtained the highest level of ISO certification.

Performance

Poor performance when multiple users of SQL Server

Oracle delivers the highest performance, keeping world records of TPC-D and TPC-C under WindowsNT.

DB2 is suitable for data warehouses and online transaction processing with high performance.

Client Support and Application Mode

SQL Server C/S structure, only supports windows customers, you can use ADO, Dao, oledb, ODBC connection.

Oracle multi-layer network computing, supporting a variety of industrial standards, can be connected by network customers such as ODBC, JDBC, OCI

DB2 cross-platform, multi-layer structure, support for ODBC, JDBC, and other customers

Easy to operate

SQL Server is easy to operate, but only has a graphical interface.

Oracle is complex and provides both GUI and command lines. The operations are the same in WindowsNT and UNIX.

DB2 is easy to operate and provides GUI and command lines at the same time. It operates the same way in WindowsNT and UNIX.

Usage risks

SQL Server completely overwritesCode, Has been tested for a long time, and is constantly delayed. Many features require time to prove. Not very compatible with earlier products. Use requires a certain risk.

Oracle is fully backward compatible with its long development experience. It is widely used. There is no risk at all.

DB2 is widely used in giant enterprises and has good downward compatibility. Low risk. For reference only
