The steps to generate a model from an existing database through reverse engineering are as follows: first connect the database and select the target database; secondly click "Tools" → "Reverse Database to Model", and then start to generate the model in reverse after selecting objects in the wizard; then you can optimize the chart layout, control field display, and customize the style to improve readability; finally you can share it by exporting it as a picture, PDF or SQL script. The entire process is suitable for a variety of mainstream databases. Paying attention to details such as database connections and table existence can successfully complete the modeling.

Generating random data can be achieved through built-in libraries or specialized tools for programming languages. 1. Use built-in modules such as Python's random and secrets, and JavaScript's Math.random() to generate basic types; 2. Use field combinations to enhance the sense of reality, such as name splicing; 3. Use special libraries such as Faker and Faker.js to generate complex structures; 4. Control the data distribution and set weight rules, cover the boundary conditions, and ensure that they meet the test needs.

Common reasons and solutions for Navicat connection failure: 1. Check whether the network connection is stable, whether the server is online, whether it can be pinged, and whether there is a firewall blocking it; 2. Check the database settings, including host name, port, database name, user name and password, confirm that the server allows remote connection and the user has corresponding access rights; 3. Check whether the server and local firewall or security software intercepts the database port, and contact the IT department if necessary; 4. Test the connection through the command line to determine whether the problem lies with Navicat itself; 5. Update Navicat to the latest version, reconfigure the connection configuration file, or try to reinstall Navicat and other database tools to troubleshoot software failures.

There are many commonly used shortcut keys in Navicat's SQL editor to improve work efficiency: 1. Basic editing shortcut keys include copy/cut/paste (Ctrl C/Ctrl X/Ctrl V), undo/redo (Ctrl Z/Ctrl Y), select all (Ctrl A), find (Ctrl F) and replace (Ctrl H); 2. Navigation shortcut keys include word-by-word movement (Ctrl ←/→), jumping the first and end of the line (Home/End), top and bottom of the document (Ctrl Home/Ctrl End), and positioning the specified line (Ctrl G); 3. Query execution and formatting shortcut keys include executing query (F5/Ctrl E), automatic formatting (Ctrl

Navicat can display a variety of performance metrics to help users monitor and optimize database performance. Its core functions include: 1. Provide real-time data on connections and sessions, such as the current number of connections, active sessions, session running time and source information, to facilitate the detection of bottlenecks caused by too many connections; 2. Display query execution time, frequency and resource usage, and provide SQL execution plan, supporting ordering by time or frequency to locate inefficient queries; 3. Monitor server-level resource usage through integrated tools, such as CPU utilization, memory consumption and disk I/O speed, to distinguish whether performance problems originate from hardware or query design; 4. Analyze table and index efficiency, including table size, number of rows, index fragmentation rate and cache hit rate, and it is recommended to rebuild inefficient indexes to improve query speed

Replacement mode means that when importing data, if a primary or unique key conflict occurs, the system will automatically delete the old record and insert a new record. The core is to ensure that the old data is completely covered, and it is suitable for scenarios such as regular and full updates and correcting wrong data. Before use, you need to back up data, confirm field matching, verify primary key settings and test the process. Different platforms operate differently. For example, if_exists='replace' parameter can be used in MySQL. Notes include: the essence of replacement is to delete old and insert new, which may affect foreign key references; avoid frequent use in big data tables; prevent error deletion of non-target data; and no historical records are retained after replacement.
