This article introduces the relevant knowledge of "what's the difference between MySQL or SQL Server". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

What's the difference between MySQL and SQL Server?

The fundamental difference is the basic principles they follow.

The basic principle followed by the two is their main difference: open vs conservatism. The narrow, conservative storage engine of SQL server is quite different from the extensible and open storage engine of MySQL server. Although you can use the Sybase engine of the SQL server, MySQL can provide a variety of options, such as MyISAM, Heap, InnoDB, and Berkeley DB. MySQL doesn't fully support unfamiliar keywords, so it has fewer related databases than SQL servers. At the same time, MySQL also lacks some stored program features, such as MyISAM engine connection to support swapping.

Issue fee: MySQL is not all free, but it is very cheap

When it comes to the cost of release, the two products adopt two very different decisions. For SQL servers, the most common way to get a free development fee is to buy Microsoft's Office or Visual Studio. However, if you want to use it in the development of commercial products, you must also buy SQL Server Standard Edition. Schools or non-profit enterprises can ignore this additional fee.

Performance: advanced MySQL

MySQL is excellent purely in terms of performance because it includes a default desktop format, MyISAM. MyISAM databases are very compatible with disk without consuming too much CPU and memory. MySQL can run on Windows systems without conflicts, and it is better to run on UNIX or similar UNIX systems. You can also get some extra performance by using a 64-bit processor. Because MySQL uses 64-bit integers most of the time internally. Yahoo! Commercial websites use MySQL as the background database.

When it comes to software performance, SQL servers are much more stable than their competitors. However, these features also come at a price. For example, additional complex operations, disk storage, memory consumption, and so on must be added. If your hardware and software can not fully support the SQL server, I suggest you choose other databases such as DBMS, because you will get better results.

Both databases can work well under. Net or J2EE, and both can take advantage of RAID.

Security function

MySQL has a binary log for changing data. Because it is binary, this log can quickly copy data from the host to the client. Even if the server crashes, the binary log will remain intact and the copied part will not be damaged.

In the SQL server, you can also record queries about SQL, but this comes at a high price.

What's the difference between MySQL and SQL Server?

Security.

Both products have their own complete security mechanisms. As long as you follow these security mechanisms, there will be no problems with the general program. Both use the default IP port, but sometimes unfortunately, these IP are also broken into by some hackers. Of course, you can also set up these IP ports yourself.

Resilience: advanced SQL server

Resilience is also a feature of MySQL, which is mainly reflected in the MyISAM configuration. This approach has its inherent shortcomings, if you accidentally damage the database, the result may result in the loss of all data. However, for the SQL server, it appears to be very stable. The SQL server can monitor the data exchange point all the time and save the process of database corruption.

Decide your choice according to your needs

For these two kinds of databases, if I have to tell you which one is better, maybe I will let you down. In my opinion, any database that is helpful to your work is a good database, no database is absolutely excellent, and no database is absolutely bad. What I want to tell you is that you should start more from your own needs, that is, what kind of tasks do you want to accomplish? Instead of simply starting from the function of the software.

If you want to build a .NET server system that can access data from many different platforms and participate in database management, then you can choose the SQL server. If you want to build a third-party site that can read data from some clients, then MySQL will be the best choice.
