The three most commonly used Chinese databases are: "MySQL", "SQL Server", and "Oracle". "MySQL" has the characteristics of small size and low cost; "SQL Server" has the characteristics of ease of use and friendly user interface; "Oracle" has the characteristics of good system portability, fast and flexible.
The three most commonly used Chinese databases are MySQL, SQL Server, Oracle
1, MySQL
MySQL is the most popular open source SQL database management system, published and supported by MySQL AB. MySQL AB is a commercial company based on MySQL development. It is a second-generation open source company that utilizes a successful business model and methodology combined with open source values. MySQL is a registered trademark of MySQL AB.
MySQL is a fast, multi-threaded, multi-user and robust SQL database server. MySQL Server supports use in mission-critical, heavy-load production systems, and it can be embedded into a large configuration (large-scale deployment) of the software.
Compared with other database management systems, MySQL has the following advantages:
(1) MySQL is a relational database management system.
(2)MySQL is open source.
(3) MySQL server is a fast, reliable and easy-to-use database server.
(4) Client/server or embedded system in MySQL server.
(5)MySQL software can be used.
2.SQL Server
SQL Server is a database management system developed by Microsoft. It is currently the most popular database for storing data on the network. It has been widely used in e-commerce, banking, insurance, electricity and other database-related industries.
The latest version of SQL Server 2005, which can only run stably on Windows operating systems, is a very important database. The parallel implementation and coexistence model are not mature, it is difficult to cope with the increasing number of users and the amount of data is limited and the scalability is limited.
SQL Server provides network and e-commerce capabilities such as rich XML and Internet standards support to easily and securely access a wide range of data over the Web, with a powerful, flexible and network-based security and application management. In addition, due to its ease of use and user-friendly interface, it has been praised by a large number of users.
3.Oracle
Oracle Database, also known as Oracle RDBMS, or Oracle for short. It is a relational database management system from Oracle Corporation. It is a product that has always been in the leading position in the database field. It can be said that the Oracle database system is currently a popular relational database management system in the world. The system has good portability, easy use, and strong functions. It is suitable for various large, medium, small, and microcomputer environments. It is a database solution with high efficiency, good reliability and adaptability to high throughput.
Currently, Oracle's products cover dozens of models of large, medium and small computers, and the Oracle database has become the most widely used relational data in the world.
Oracle database products have the following excellent features.
(1) Compatibility
Oracle products use standard SQL and have been tested by the National Institute of Standards and Technology (NIST). Compatible with IBM SQL/DS, DB2, ANGEL IDMS/R.
(2) Portability
Oracle's products can run on a wide range of hardware and operating system platforms. Can be installed on more than 70 different VMS systems, DOS, UNIX, Windows and other operating systems, minicomputers;
(3) Association
Oracle connects with various communication networks, Supports various protocols (TCP/IP, DECnet, LU6.2, etc.).
(4) High productivity
Oracle provides a variety of development tools, which can greatly facilitate further development.
(5) Open
Oracle’s compatibility, portability, connectivity and high productivity Oracle RDBMS has good openness.

Getting Started with SQL: Essential Concepts and SkillsApr 22, 2025 am 12:01 AMSQL is a language used to manage and operate relational databases. 1. Create a table: Use CREATETABLE statements, such as CREATETABLEusers(idINTPRIMARYKEY, nameVARCHAR(100), emailVARCHAR(100)); 2. Insert, update, and delete data: Use INSERTINTO, UPDATE, DELETE statements, such as INSERTINTOusers(id, name, email)VALUES(1,'JohnDoe','john@example.com'); 3. Query data: Use SELECT statements, such as SELEC
SQL: The Language, MySQL: The Database Management SystemApr 21, 2025 am 12:05 AMThe relationship between SQL and MySQL is: SQL is a language used to manage and operate databases, while MySQL is a database management system that supports SQL. 1.SQL allows CRUD operations and advanced queries of data. 2.MySQL provides indexing, transactions and locking mechanisms to improve performance and security. 3. Optimizing MySQL performance requires attention to query optimization, database design and monitoring and maintenance.
What SQL Does: Managing and Manipulating DataApr 20, 2025 am 12:02 AMSQL is used for database management and data operations, and its core functions include CRUD operations, complex queries and optimization strategies. 1) CRUD operation: Use INSERTINTO to create data, SELECT reads data, UPDATE updates data, and DELETE deletes data. 2) Complex query: Process complex data through GROUPBY and HAVING clauses. 3) Optimization strategy: Use indexes, avoid full table scanning, optimize JOIN operations and paging queries to improve performance.
SQL: A Beginner-Friendly Approach to Data Management?Apr 19, 2025 am 12:12 AMSQL is suitable for beginners because it is simple in syntax, powerful in function, and widely used in database systems. 1.SQL is used to manage relational databases and organize data through tables. 2. Basic operations include creating, inserting, querying, updating and deleting data. 3. Advanced usage such as JOIN, subquery and window functions enhance data analysis capabilities. 4. Common errors include syntax, logic and performance issues, which can be solved through inspection and optimization. 5. Performance optimization suggestions include using indexes, avoiding SELECT*, using EXPLAIN to analyze queries, normalizing databases, and improving code readability.
SQL in Action: Real-World Examples and Use CasesApr 18, 2025 am 12:13 AMIn practical applications, SQL is mainly used for data query and analysis, data integration and reporting, data cleaning and preprocessing, advanced usage and optimization, as well as handling complex queries and avoiding common errors. 1) Data query and analysis can be used to find the most sales product; 2) Data integration and reporting generate customer purchase reports through JOIN operations; 3) Data cleaning and preprocessing can delete abnormal age records; 4) Advanced usage and optimization include using window functions and creating indexes; 5) CTE and JOIN can be used to handle complex queries to avoid common errors such as SQL injection.
SQL and MySQL: Understanding the Core DifferencesApr 17, 2025 am 12:03 AMSQL is a standard language for managing relational databases, while MySQL is a specific database management system. SQL provides a unified syntax and is suitable for a variety of databases; MySQL is lightweight and open source, with stable performance but has bottlenecks in big data processing.
SQL: The Learning Curve for BeginnersApr 16, 2025 am 12:11 AMThe SQL learning curve is steep, but it can be mastered through practice and understanding the core concepts. 1. Basic operations include SELECT, INSERT, UPDATE, DELETE. 2. Query execution is divided into three steps: analysis, optimization and execution. 3. Basic usage is such as querying employee information, and advanced usage is such as using JOIN connection table. 4. Common errors include not using alias and SQL injection, and parameterized query is required to prevent it. 5. Performance optimization is achieved by selecting necessary columns and maintaining code readability.
SQL: The Commands, MySQL: The EngineApr 15, 2025 am 12:04 AMSQL commands are divided into five categories in MySQL: DQL, DDL, DML, DCL and TCL, and are used to define, operate and control database data. MySQL processes SQL commands through lexical analysis, syntax analysis, optimization and execution, and uses index and query optimizers to improve performance. Examples of usage include SELECT for data queries and JOIN for multi-table operations. Common errors include syntax, logic, and performance issues, and optimization strategies include using indexes, optimizing queries, and choosing the right storage engine.
