#Overview

Tachybase uses a proprietary Domain-Specific Language called collections to uniformly describe data structures from various sources, making data management, analysis, and application more intuitive and convenient.

To quickly create various data models, different types of data tables have been designed to support:

• General Table: Standard common field settings;
• Comment Table: Stores user feedback and comments on content;
• Tree Structure Table: Data structure for representing hierarchical relationships, such as directories or categories;
• Expression Table: Used to express dynamic workflow scenarios;
• Calendar Data Table: Used to store date and time-related event information;
• File Data Table: Used to manage file metadata, such as file name, path, and size;
• Inheritance Table: Create a parent table, then derive child tables from the parent table;
• SQL Data Table: Used to store data obtained through SQL queries;
• External Data Table (FDW): Used to connect to remote data tables;
• Connect Database View: Used to provide data views and integration between different data models;
