What is the difference between MySQL, SqlServer and Oracle? In response to this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more small partners who want to solve this problem find a simpler and easier way.

I. MySQL

Advantages:

Small size, fast speed, low total cost of ownership, open source;

Support multiple operating systems;

Is an open source database, providing interfaces to support multi-language connection operations;

MySQL's core program uses fully multithreaded programming. Threads are lightweight processes that provide flexibility to provide services to users without excessive system resources. mysql, implemented in multithreading and C language, can easily make full use of CPU;

MySql has a very flexible and secure permissions and password system. When clients connect to MySql servers, all password transfers between them are encrypted, and MySql supports host authentication;

Supports ODBC for Windows, supports all ODBC 2.5 functions and many other functions, can use Access to connect to MySql server, so that the application is extended;

Support large databases, which can easily support databases with tens of millions of records. As an open source database, it can be modified for different applications.

Have a very fast and stable thread-based memory allocation system that can be used continuously without worrying about its stability;

MySQL also provides a high degree of versatility, providing many different user interfaces, including command-line client operations, web browsers, and a wide variety of programming language interfaces, such as C+, Perl, Java, PHP, and Python. You can use a prepackaged client, or you can write a suitable application yourself. MySQL is available on Unix, Windows, and OS/2 platforms, so it can be used on personal computers or servers.

Disadvantages:

Hot backups are not supported;

MySQL's biggest weakness is its security system, which is mostly complex rather than standard, and changes only when mysqladmin is called to reread user permissions;

There is no stored procedure language, which is the biggest limitation for programmers accustomed to enterprise databases;

MySQL prices vary by platform and installation. MySQL for Linux is free if installed by the user himself or by a system administrator rather than by a third party, and a license fee must be paid for the third option. Unix or Linux installation is free, Unix or Linux third-party installation is charged.

SqlServer

Advantages:

ease of use, scalability for distributed organizations, data warehouse functionality for decision support, tight integration with many other server software, good price/performance ratio, etc.;

It brings flexibility to data management and analytics, allowing organizations to respond to rapidly changing environments and gain a competitive advantage. From a data management and analytics perspective, it is important to transform raw data into business intelligence and take advantage of the opportunities presented by the Web. As a complete database and data analysis package, SQL Server opens the door to victory for the rapid development of a new generation of enterprise-class business applications and for enterprises to win core competitive advantages. A record-holder for important benchmark scalability and speed awards, SQL Server is a fully Web-enabled database product that provides core support for Extensible Markup Language (XML) and the ability to query over the Internet and outside firewalls;

Disadvantages:

Openness: SQL Server can only run on Windows without any openness. Operating system stability is very important for databases. Windows9X series products focus on desktop applications. NT server is only suitable for small enterprises. Windows platform depends on security and scalability. It is very limited. It is tried and tested, especially for large databases.

Scalability Parallelism: SQL server implements parallel and coexistence models and matures to handle increasing numbers of users and data volumes with limited scalability.

Security: No security certificates have been obtained.

Performance: SQL Server performs well with multiple users.

Client support and application mode: Client support and application mode. SQL Server C/S architecture only supports ADO, DAO, OLE DB, ODBC connections for Windows clients.

Use risk: SQL server completely rewritten code experienced long testing delays Many features take time to prove and are fully compatible.

Third, Oracle

Advantages:

Openness: Oracle can run on all major platforms (including Windows) and fully supports all industry standards. It adopts a completely open strategy to enable customers to choose the right solution for developers.

Oracle Parallel Server extends Windows NT capabilities by enabling group nodes to share cluster work. Windows NT provides high availability and scalability cluster solutions that meet the need for users to move databases to UNIX Oracle Parallel Server has a high degree of integration with various UNIX platform clustering mechanisms.

Safety: ISO certification at the highest certification level.

Performance: Oracle maintains the TPC-D and TPC-C world records for high performance on open platforms.

Client support and application mode: Oracle multi-level network computing supports a variety of industrial standards with ODBC, JDBC, OCI and other network client connections.

Use risk: Oracle's long development experience is fully backward compatible and has low risk of widespread use.

Disadvantages:

High requirements for hardware;

More expensive;

Management maintenance trouble some;

The operation is more complex and requires higher technical content.

About Mysql, SqlServer and Oracle is the difference between what questions to share here, I hope the above content can be of some help to everyone, if you still have a lot of doubts not solved, you can pay attention to the industry information channel to learn more related knowledge.
