What is the difference between SQL Server and MySQL database? I believe many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1, advantage analysis: MYSQL is short, easy to use, easy to operate and free to use. Compared with other databases, there are more characteristic and practical syntax. SQL can be regarded as a large database, stable and can be used as a data warehouse for general large systems, and its running speed is obviously faster than that of MYSQL (this advantage is obvious under massive data).

2, defect analysis: MYSQL is difficult to act as the data warehouse of a large system, the running speed is slow, it is not stable enough, and the line is dropped. SQLSERVER is expensive (not to mention 5 yuan piracy, of course), and it is more difficult to use than MYSQL. After all, things are a little bit bigger.

3, press your supplement (how to log in): MySQL has its own text interface client, which is not as convenient to use as a mouse click (but it's good to get used to it). Of course, pairing MYSQL has professional client software, I use the SQLYOG519 version, various operations are really very convenient to say. SQLSERVER is logged in with its own query analyzer:) the premise of both is that the database service is open, and you need to know the username and password at the time of installation.

For program developers, the two back-end databases currently in use are MySQLandSQLServer. The most basic similarities between the two are data storage and belonging to the query system. You can use SQL to access data from both databases because they both support ANSI-SQL. Also, both database systems support binary keywords and key indexes, which greatly speeds up the query. At the same time, both provide various formats that support XML. Apart from the obvious difference in the price of software, is there any obvious difference between the two products? How do you choose between the two? Let's look at the main differences between the two products, including release costs, performance, and their security.

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 offers a variety of options, such as MyISAM,Heap,InnoDB,andBerkeleyDB. 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 VisualStudio. However, if you want to use it in the development of commercial products, you must also buy SQLServerStandardEdition. Schools or non-profit enterprises can ignore this additional fee.

Performance: advanced MySQL

In terms of pure performance, MySQL is excellent 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 do not fully support SQL servers, I suggest you choose other databases such as DBMS, because you will get better results.

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.

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, it is very stable for the SQL server. 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 good, and no database is 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 choice.

After reading the above, have you mastered the difference between SQL Server and MySQL databases? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
