What is Access?

AccessThe full name is Microsoft Office Access, which is a relational database management system released by Microsoft; it is the graphical user interface and software development of Microsoft's database engine. Tools are combined into a database management system.

Access stores data in its own format in the Access Jet-based database engine. It can also directly import or link data stored in other applications and databases.

The role of Access:

1. Used for data analysis: access has powerful data processing and statistical analysis capabilities. Using the query function of access, you can easily Perform various summary, average and other statistics. And the statistical conditions can be flexibly set.

2. Used to develop software:

Software developers and data architects can use Microsoft Access to develop application software, and "advanced users" can use it to build software applications. Such as production management, sales management, inventory management and other types of enterprise management software, its biggest advantage is: easy to learn! Non-computer majors can also learn it.

Defects of Access:

1. When the database is too large, generally the performance will start to decline when the ACCESS database reaches about 100M! (For example: too many visitors may cause IIS to freeze, excessive consumption of server resources, etc.)

2. It is prone to various database problems caused by too fast database refresh frequency.

3. The ACCESS database is not as secure as other types of databases.

4. Once the ACCESS forum gets bigger, it is easy to have database problems. When the forum database is more than 50M, there are about 50,000 posts, and there are about 100 people online, your forum will basically be there. It takes time to process the database, and the database is likely to be slow at this time.
