What are the potential pitfalls of using multiple user group tables in a database design?

Potential pitfalls of using multiple user group tables in a database design include increased complexity, difficulty in managing permissions across multiple tables, and potential for inconsistencies or conflicts between different group tables. To solve this issue, consider consolidating user group information into a single table with a column to differentiate between different group types. 

// Example of consolidating user group information into a single table
CREATE TABLE user_groups (
    group_id INT PRIMARY KEY,
    group_name VARCHAR(50),
    group_type ENUM('admin', 'editor', 'viewer')
);

// Example of how to differentiate between different group types in the user_groups table
INSERT INTO user_groups (group_id, group_name, group_type)
VALUES (1, 'Admin Group', 'admin');

INSERT INTO user_groups (group_id, group_name, group_type)
VALUES (2, 'Editor Group', 'editor');

INSERT INTO user_groups (group_id, group_name, group_type)
VALUES (3, 'Viewer Group', 'viewer');
