The author has been oriented to web application development for 13 years. In the project practice and learning, he replaced the old with the new, absorbed the advantages, accumulated from the direction of high quality, strong specification, and rapid development, and formed a generator tool to reduce the difficulty of project back-end development.

The navicat model tool creates and manages ER diagrams, imports/synchronizes structures from the database to the database, and then uses this generator to synchronize c# entities with one click, as well as various standardized styles and grammars that you can't imagine, supports caching, and supports databases 99% type, mining database characteristics, avoiding excessive duplication of labor and non-standard and unrobust codes.

Advantage:

• 1. Generate a feature-rich database SDK based on primary key, unique key, and foreign key (1-to-1, 1-to-many, many-to-many);
• 2. Strictly control the database, avoid creating tables or fields at will, and have standard ER diagram database specifications;
• 3. Unify and standardize database operation classes and methods (compared with EF's too casual usage, which is much easier to manage), and concentrate on business;
• 4. Optimize every detail, and never allow low-level errors to interfere with our business logic (compared to ORM, the generated code is more focused);

Suitable for the occasion:

• 1. For new project development, only design data ER diagrams, without considering db related codes;
• 2. The old project database access method is unsightly, the more tables, the greater the benefits;

Download the winform client of the generator, it is recommended to install the command tool dotnet tool install -g GenMy

dotnetGen maintains the same development and usage habits, and realizes rapid development for three databases including mysql, SQLServer, and PostgreSQL, and can also be used in combination.
