What is an SQL Server database? What is the difference with access database?

After getting started with the Access database, we started learning about the SQL Server database. In the course of learning, we will inevitably ask: What is an SQL Server database? What is the difference between it and the Access database?

Access is an associated database management system released by Microsoft. It combines Microsoft Jet Database Engine and graphical user interface, and is one of the Microsoft Office System programs. Access has powerful data processing and statistical analysis capabilities. Using the access query function, you can conveniently perform various statistics such as summary and average, which can be used to analyze data, in addition, you can flexibly set statistical conditions. In addition, it is easy to learn and meets the needs of enterprise management staff at a low cost. In addition, it is used to store data when developing Web applications for small websites.

Let's look back at SQL Server. SQL is a standard computer language used to access and process databases. SQL is short for structured query language. It is a structured query language and a language for database query and programming. SQL queries the database; SQL retrieves data from the database; SQL inserts new records into the database; SQL updates data in the database; SQL deletes records from the database; SQL can create a new database; SQL can create a new table in the database; SQL can create a stored procedure in the database; SQL can create a view in the database; SQL allows you to set permissions for tables, stored procedures, and views. At the same time, SQL is used as the standard language of the relational database management system. It is an advanced non-procedural programming language and an important tool for communicating with database servers and clients. It allows users to work on high-level data structures. Continue to talk about SQL Server. SQL Server is a relational database management system. Therefore, the former is used as a standardized structure query language, and the latter is a relational database management system, which is a comprehensive database platform. In comparison, the ACCESS database is a desktop database system, and it can develop its own desktop database application (UI ), it can also be used as a front-end development tool to develop applications (such as SQL Server, DB2, and Oracle) with other databases ). However, the access database has a small data storage capacity and is not secure enough, which is less adaptable to high-intensity operations. SQL Server is a relational database management system with high security, real client/server architecture, and graphical user interface, making system management and database management more intuitive and simple, A wide range of programming interface tools provide users with more options for programming. It is highly scalable and can be used across multiple platforms. It supports Web technologies, so that users can easily publish data in databases to web pages. However, compared with the Access database, the SQL Server database is not complex. If there are not many requirements on the database during the operation, the ACCESS database is relatively easy to operate.
