What is the difference between a SQL Server database and a MySQL database?

What is the difference between a SQL Server database and a MySQL database? A lot of friends in the IT industry. For SQL Server database and MySQL database often confuse, think these two kinds of database is the same, otherwise, today we analyze the difference between these two kinds of database:
What is the difference between a SQL Server database and a MySQL database
1, Advantage Analysis: MySQL short, easy to use, easy to operate, free of charge. Compared with other databases have the characteristics and practical syntax more. SQL is also a large database, stable, can do the general large system of data warehouse, running speed is significantly faster than MySQL (the advantage of huge data is obvious).

2, shortcomings analysis: MySQL difficult to assume the large system of data warehouse, running slow, not stable enough, there is the situation of the drop line. SQL Server is expensive (not to mention 5 of dollars piracy), it is more difficult to use than MySQL, after all, things Big said more points.

3, according to your supplement (how to log in): MySQL own text interface client, use up to say no mouse point convenient (but accustomed to it), of course, matching MySQL has a professional client software, I am using SQLYOG519 version, various operations really is very convenient to say. SQL Server uses its own Query Analyzer to log in: The premise is that the database service is open, and you need to know the user name password at the time of installation OH:)

For program developers, the two most popular background databases currently used are MySQL and SQL Server. The most basic similarity between the two is that the data is stored and belongs to the query system. You can use SQL to access the data for both databases because they all support ansi-sql. Also, both of these database systems support binary keywords and key indexes, which greatly accelerates query speed. At the same time, both provide various formats that support XML. Apart from the obvious differences in the price of software, what are the obvious differences between these two products? How do you choose between the two? Let's look at the major differences between the two products, including the issue fee, performance, and their security.

The fundamental difference is that they follow the basic principles

The basic principles that they follow are their main differences: Open vs Conservative. The narrow, conservative storage engine of SQL Server is different from the extensible, open storage engine absolutely of MySQL server. While you can use the Sybase engine of SQL Server, MySQL can provide more options such as Myisam,heap, InnoDB, and BerkeleyDB. MySQL does not fully support unfamiliar keywords, so it is less relevant than SQL Server database. At the same time, MySQL also lacks the functions of some stored programs, such as the MyISAM engine to support the Exchange function.

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

When it comes to the cost of a release, the two products adopt two absolutely different decisions. For SQL Server, the most common way to get a free development fee is to purchase Microsoft Office or VisualStudio fees. However, if you want to use the development of commercial products, you must also purchase SQL Server standardedition. Schools or non-profit enterprises may not consider this additional fee.

Performance: Advanced MySQL

In purely performance terms, MySQL is pretty good because it contains a default desktop format, MyISAM. The MyISAM database is very compatible with the disk without consuming too much CPU and memory. MySQL can run on windows without conflict, and it is better to run on UNIX or similar UNIX-like systems. You can also get some additional performance by using a 64-bit processor. Because MySQL often uses 64-bit integer processing in the interior. Yahoo! 's commercial website uses MySQL as a back-end database.

When it comes to software performance, the stability of SQL Server is much stronger than its competitors. However, these features also have to pay a price. For example, additional complex operations, disk storage, memory loss, and so on must be added. If your hardware and software do not fully support SQL Server, I suggest you better choose other databases like DBMS, because you will get better results.

Security features

MySQL has a binary log that is used to change the data. Since it is binary, this log can quickly replicate data from the host to the client. Even if the server crashes, the twos log will remain intact and the copied portions will not be corrupted.

In SQL Server, you can also log queries about SQL, but this takes a high price.

Security

Both of these products have their own complete security mechanism. As long as you follow these security mechanisms, there is no problem with the general program. Both use the default IP port, but sometimes unfortunately, these IPs are also hacked into by some hackers. Of course, you can also set these IP ports yourself.

Resiliency: Advanced SQL Server

Recoverability is also a feature of MySQL, which is mainly manifested in the MyISAM configuration. This approach has its inherent shortcomings, and if you accidentally damage the database, the results can result in all data loss. However, it is very stable for SQL Server. SQL Server can monitor the data exchange point at all times and can save the process of database corruption.

Decide your choice as needed

For both of these databases, if you want me to say which one is better, maybe I'll let you down. In my opinion, any pair of databases that are helpful to your work are good databases, 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 with the functionality of the software.

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