mssql is SqlServer. full name: Microsoft ?SQL Server; it is a product of Microsoft.
So that's the difference between mysql and SqlServer.
sqlserverBenefits:
Ease of use, scalability for distributed organizations, data warehousing capabilities for decision support, tightly coupled integration with many other server software, good price/performance ratio, etc.;
Bringing flexibility to data management and analysis. Allows units to respond comfortably in a rapidly changing environment, thereby gaining a competitive advantage. From a data management and analytics perspective, it's important to turn raw data into business intelligence and capitalize on the opportunities presented by the Web.
As a complete database and data analytics package, SQL Server opens the door for rapid development of a new generation of enterprise-class business applications that give organizations a core competitive advantage.

Disadvantages:
Openness: SQL Server can only run on windows without any openness. The stability of the operating system is very important for the database. Windows 9X series products are emphasized on desktop applications. Proven to handle large databases in particular;
Scalability and parallelism: SQL server parallel implementation and **** storage model is not mature and difficult to deal with the increasing number of users and data volume scalability is limited;
Security: no security certificates have been obtained.
Performance : SQL Server multi-user performance ;
Client support and application model : Client support and application model. Only support C/S mode, SQL Server C/S structure only supports windows clients with ADO, DAO, OLEDB, ODBC connection;
Use Risk: SQL server completely rewritten code experienced a long test break delay many features need time to prove and very compatible;
MySqlAdvantages:
Small, fast, low total cost of ownership, open source;
Support for multiple operating systems;
It is an open-source database that provides interfaces to support multiple language connections
The core program of MySql uses full multi-threaded programming. Threads are lightweight processes that can flexibly provide services to users without overloading system resources. Implemented in multi-threaded and C, MySql makes it easy to fully utilize the CPU;
MySql has a very flexible and secure permissions and password system. When a client connects to a MySql server, all passwords transmitted between them are encrypted, and MySql supports host authentication;
Support for ODBC for Windows, support for all ODBC 2.5 functions and many other functions, you can connect to a MySql server with Access, so the application can be extended;

With a very fast and stable thread-based memory allocation system, you can continue to use it without worrying about its stability.
MySQL also offers a high degree of versatility, providing many different user interfaces, including command-line clients, web browsers, and interfaces to a wide variety of programming languages, such as C+, Perl, Java, PHP, and Python.
You can use a pre-packaged client, or simply write your own suitable application. MySQL is available for Unix, Windows, and OS/2, so it can be used on PCs or servers;
Disadvantages:
No support for hot backups;
The biggest disadvantage of MySQL is its security system, which is largely complex rather than standard. Also it only changes until mysqladmin is called to reread user permissions;
There is not a Stored Procedure (Stored Procedure) language, which is the biggest limitation for programmers accustomed to enterprise-class databases;
The price of MySQL varies with the platform and the method of installation. mySQL for Linux is not supported if it is installed by the user MySQL for Linux is free if installed by the user or system administrator rather than by a third party, and a license fee must be paid for a third option.
