关于

The DataModel mind map template provides a visual database schema for a CRM and e-commerce system, covering 8 core entities (navigation, company_type, job_title, company, contact, order, order_item, product) with 57 nodes detailing primary keys, foreign keys, and data types. This DataModel template is ideal for developers, data architects, and students designing relational databases. Key nodes include 'pk_company' (int) and 'company_name' (varchar(100)), illustrating how entities like 'company' and 'contact' are linked via foreign keys such as 'fk_company'. The schema also specifies data types like 'varchar(50)' for 'company_type' and 'date' for 'date_order', making it a practical cheat sheet for database normalization.

常见问题

The template covers 8 entities: navigation, company_type, job_title, company, contact, order, order_item, and product. Each entity includes its primary key, relevant attributes, and data types.

It uses a hierarchical mind map with root 'DataModel' and branches for each table. Each branch lists columns with data types (e.g., varchar(100), int, date) and foreign keys (e.g., fk_company) to show relationships.

Yes. Open the .xmind file in Xmind, then add, remove, or rename nodes to match your schema. You can also change data types or add new entities by branching off the root.

Absolutely. It provides a clear visual representation of tables, keys, and relationships, making it a great study aid for understanding normalization and foreign key constraints.

Common types include int for primary keys, varchar(50/100) for text fields, date for dates, number for prices, and media for images like company logos.
