Workbench is an ER and database modeling tool designed specifically for MySQL. It provides visual design, model building, and database management functions, helping to create new physical data models and reverse or Forward engineering and change management capabilities for modifying existing MySQL databases.
The operating environment of this tutorial: windows7 system, MySQL Workbench version 6.3.9, DELL G3 computer
Workbench is a program specially designed for MySQL ER and database modeling tool, an integrated desktop software, is also a next-generation visual database design and management tool. It has both open source and commercial versions. The software supports Windows and Linux systems and can be downloaded from https://dev.mysql.com/downloads/workbench/.
MySQL Workbench is a visual database design software that helps create new physical data models and modify existing MySQL databases through reverse or forward engineering and change management capabilities. It also supports all components that make up the database. Objects such as tables, views, stored procedures, triggers, etc.
MySQL Workbench provides visual design, model building, and database management functions for database administrators, program developers, and system planners. It includes tools for creating complex data modeling ER models, forward and reverse database engineering, and can also be used to perform documentation tasks that often take a lot of time and require difficult changes and management. MySQL Workbench is available on Windows, Linux, and Mac.
Layout introduction
Create database
First step: Click on the red area in the picture below
## Step 2: Name the database and press Press Apply, Apply and finish in order
Step 1: Select the database and double-click
##Step 2: Right-click and select tables , select create tables;
##Step 3: Fill in the table Field information
PK: primary key primary key NN: not null non-empty
- UQ: unique unique index
- BIN: binary binary data (larger than text)
- UN: unsigned unsigned (non-negative number)
- ZF: zero fill filled with 0. For example, if the field content is 1 int(4), the content is displayed as 0001
- AI: auto increment self-increment
- You can double-click the input field information in the above list, or directly enter the information in the input box below.
Import data
Step 1: Right-click the table and select Select Rows -Limit 1000
Step 2: Small amount of data Write
Three steps: A large number of data import methods
Method one:
Click the button pointed by the arrow, select the .csv file (save excel as a sub-type file), confirm to complete the import; however, this method has a flaw, it is imported in the order of the fields in the table. , all excel fields need to be in exactly the same order as the fields in the table. If not, just insert empty columns in excel;
Method 2:
It is more complicated, but manual correspondence can be achieved:
1. Select the table to be imported and right-click, as shown in the figure: [Never select the first one]
2. Select the imported file to be prepared, and then continue to next
Note: Click the button marked with a red circle to pop up the options (Opinions). Select CR LF (windows system "/r/n") at the line interval; encoding format utf-8; select the corresponding field in the list part as needed; then click Next until the execution is completed, and the data import is completed;

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

MySQL/InnoDB supports four transaction isolation levels: ReadUncommitted, ReadCommitted, RepeatableRead and Serializable. 1.ReadUncommitted allows reading of uncommitted data, which may cause dirty reading. 2. ReadCommitted avoids dirty reading, but non-repeatable reading may occur. 3.RepeatableRead is the default level, avoiding dirty reading and non-repeatable reading, but phantom reading may occur. 4. Serializable avoids all concurrency problems but reduces concurrency. Choosing the appropriate isolation level requires balancing data consistency and performance requirements.

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.
