What is the difference between oracle database and sql

The difference between oracle database and sql: 1. "sql Server" can only run on windows, while oracle can run on all mainstream platforms; 2. "sql Server" parallel implementation and coexistence model are not Mature, limited scalability, while Oracle provides high availability and high scalability cluster solutions; 3. "SQL Server" is simple to operate and only has a graphical interface, while Oracle is more complex and provides both GUI and command line.

The operating environment of this tutorial: Windows 10 system, Oracle version 12c, Dell G3 computer.

What is the difference between oracle database and sql

1. Openness

SQL Server can only run on windows and has no openness at all , The stability of the operating system is very important to the database. Windows9X series products focus on desktop applications, and NT server is only suitable for small and medium-sized enterprises. Moreover, 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.

Oracle can run on all major platforms (including windows). Fully supports all industry standards. Adopt a completely open strategy. This enables customers to choose the most suitable solution. Full support to developers.

2. Scalability, parallelism

SQL server parallel implementation and coexistence model are not mature, and it is difficult to handle the increasing number of users and data volumes, and scaling Sex is limited.

Oracle Parallel Server extends the capabilities of windownt by enabling a group of nodes to share work in the same cluster, providing high availability and high scalability cluster solutions. If windowsNT cannot meet the needs, users can move the database to UNIX. Oracle's parallel server has a high degree of integration with the cluster mechanisms of various UNIX platforms.

3. Performance

SQL Server has poor performance with multiple users.

Oracle has the highest performance and maintains the world record of TPC-D and TPC-C under the open platform.

4. Client support and application mode

SQL Server C/S structure only supports windows clients and can be connected using ADO, DAO, OLEDB, and ODBC.

Oracle multi-level network computing supports multiple industrial standards and can be connected with network clients such as ODBC, JDBC, and OCI.

5. Operation

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

Oracle is more complex, providing both GUI and command line, and the operation is the same under windowsNT and unix.

6. Risks of use

SQL server is a completely rewritten code that has gone through long-term testing and continuous delays, and many functions take time to prove. Not very compatible.

Oracle has long-term development experience and is fully backward compatible. Be widely used. There is no risk at all. In the final price, ORACLE is more expensive than SQLSRVER.
