Common database software introduction:
1. MySQL
MySQL is the most popular open source SQL database management system , which is developed, published and supported by MySQL AB.
MySQL is a fast, multi-threaded, multi-user, robust SQL database server. MySQL Server supports use in mission-critical, heavy-load production systems, and can also be embedded in a mass-deployed software.
2. SQL Server
SQL Server is a database management system developed by Microsoft. It is the most popular database for storing data on the Web. It has been widely used Suitable for database-related industries such as e-commerce, banking, insurance, and electricity.
SQL Server provides numerous Web and e-commerce features, such as rich support for XML and Internet standards, easy and secure access to data through the Web, and is powerful, flexible, Web-based and secure application management, etc. Moreover, due to its easy operation and friendly operation interface, it is deeply loved by the majority of users.
3. Oracle
Oracle has always been a leader in the database field. At present, Oracle products cover dozens of models of large, medium and small computers, and the Oracle database has become one of the most widely used relational data systems 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, INGRES, IDMS/R, etc.
2. Portability
Oracle's products can run on a wide range of hardware and operating system platforms. It can be installed on more than 70 different large, medium and small computers; it can work under various operating systems such as VMS, DOS, UNIX and Windows.
3. Connectability
Oracle can be connected to a variety of communication networks and supports various protocols (TCP/IP, DECnet, LU6.2, etc.).
4. High productivity
Oracle products provide a variety of development tools, which can greatly facilitate users for further development.
5. Openness
Oracle's good compatibility, portability, connectability and high productivity make Oracle RDBMS have good openness.

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
