SQL Server introduction

SQL Server is not only a relational database system, but also a scalable, high-performance database management system designed for distributed client / server computing. It combines with WindowsNT organically and provides a transaction-based enterprise information management system. Like all database management systems, SQL Server supports the standard SQL language, and it also includes T-SQL, its own SQL implementation. SQL Server Management Studio (SSMS) is the main interface tool of SQL Server, which supports 32-bit and 64-bit environments. In addition, SQL Server provides several versions with different functions and options to meet the needs of different users.

The standard model is mainly aimed at small and medium-sized enterprises, because there are no size and user restrictions, so it can be used as a small web server or a back-end database for branch offices.

Free type:

Free release, with a small number of features and limits the size of the database and users, can be used as a substitute for Access database

Advantages and disadvantages of SQL Server

Advantages:

1. By creating a uniqueness index, we can ensure the uniqueness of each row of data in the database table.

2. The speed of data retrieval can be greatly accelerated by creating an index.

3. By using the index, the optimization hidden device can be used in the process of query to improve the performance of the system.

4. When using grouping and sorting clauses for data retrieval, the time of grouping and sorting in the query can also be significantly reduced.

Disadvantages:

1. It can only run on the windows platform, and the platform is single and not open.

2. The parallel implementation and coexistence model is not mature, it is difficult to deal with large-scale data, and the scalability is limited.

3. The performance will become very poor and unstable when users have too many connections.

4. The client supports the application mode, and only supports the CCMUP S mode.

What are the advantages and disadvantages of SQL Server to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
