This article introduces to you what is the difference between SqlServer, MySQL and Oracle. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.
1. MySQL
Advantages:
Small size, high speed, low total cost of ownership, open source
Support for multiple operating systems
Is an open source database that provides interfaces that support multi-language connection operations
The core program of MySQL adopts complete multithreaded programming. Threads are lightweight processes that can flexibly provide services to users without too many 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 customers connect to the MySql server, all password transfers between them are encrypted, and MySql supports host authentication
Support ODBC for Windows, support all ODBC 2.5functions and many other functions, you can use Access to connect to the MySql server, so that the application can be extended
Support for large databases, can easily support tens of millions of records of the database. As an open source database, it can be modified for different applications.
With a very fast and stable thread-based memory allocation system, you don't have to worry about its stability.
MySQL also provides a high degree of diversity, providing many different user interfaces, including command line client operations, web browsers, and a variety of programming language interfaces, such as Category Perl, Java, PHP, and Python. You can use a pre-packaged client, or you can simply write an appropriate application yourself. MySQL can be used on platforms such as Unix,Windows and OS/2, so it can be used on personal computers or servers.
Disadvantages:
Hot backup is not supported
The biggest disadvantage of MySQL is that its security system is mainly complex rather than standard, and it only changes when mysqladmin is called to reread user permissions.
There is no stored procedure (Stored Procedure) language, which is the biggest limitation for programmers accustomed to enterprise databases
The price of MySQL varies with platform and installation. Linux's MySQL is free if it is installed by the user or by the system administrator rather than by a third party, while the third option must pay a license fee. Unix or linux installation is free of charge, Unix or Linux third-party installation fee.
II. SqlServer
Advantages:
Ease of use, scalability for distributed organizations, data warehouse functions for decision support, integration closely related to many other server software, good performance-to-price ratio, etc.
It brings flexibility to data management and analysis, allowing units to respond calmly in a rapidly changing environment, thus gaining competitive advantage. From a data management and analysis perspective, it is important to convert raw data into business intelligence and to take full advantage of the opportunities presented by Web. As a complete database and data analysis package, SQLServer opens the door for the rapid development of a new generation of enterprise business applications and for enterprises to win the core competitive advantage. As the record holder of the important benchmark scalability and speed award, SQLServer is a database product with full Web support, providing core support for Extensible markup language (XML) and the ability to query on Internet and outside firewalls
Disadvantages:
Openness: SQL Server can only run on windows without the slightest open operating system stability is very important to the database Windows9X series of products focus on desktop applications NT server is only suitable for small businesses and the windows platform is very limited in reliability, security and scalability, like unix, especially in dealing with large databases.
Scalable parallelism: SQL server parallel implementation and coexistence model and mature difficult to handle the growing number of users and limited scalability of data volumes.
Security: no security certificate has been obtained.
Performance: SQL Server has good performance when it is multi-user.
Client support and application mode: client support and application mode. It only supports windows S mode, and the SQL Server Cpact S structure only supports windows customers to connect with ADO, DAO, OLEDB, and ODBC.
Usage risk: SQL server completely rewrites the code after a long period of testing, breaking delays, and many features take time to prove and are very compatible.
III. Oracle
Advantages:
Openness: Oracle can run on all major platforms (including windows) to fully support all industry standards and adopt a fully open strategy to enable customers to choose suitable solutions to fully support developers.
Scalability, parallelism: oracle parallel servers provide high usability and high scalability cluster solutions by making group nodes share the same cluster work. WindowsNT can meet the needs of users to move databases. UNIXOracle parallel servers have a high degree of integration for all kinds of UNIX platform cluster mechanisms.
Security: obtain the highest certification level of ISO standard certification.
Performance: the high performance of Oracle holds the world record for TPC-D and TPC-C on open platform.
Client support and application mode: Oracle multi-level network computing supports a variety of industrial standards for ODBC, JDBC, OCI and other network customer connections.
Use risk: Oracle's long development experience is fully backward compatible with low risk for a wide range of applications.
Disadvantages:
The requirement of hardware is very high.
The price is relatively high.
Management and maintenance is more troublesome.
The operation is more complex and requires high technical content.
About SqlServer, MySQL, Oracle what is the difference between what is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
