Basic dynamic CRUD web application

This is a basic CRUD (Create, Read, Update, Delete) web application made in a few hours which dynamically adapts to the database structure. Nothing regarding a specific database has been hard coded - the application will allow CRUD operations on any MySQL database you connect it to. Forms for inserting new records and tables for showing data from tables are dynamically created based on the table structure.

Features

  • offers basic CRUD operations for any MySQL database - nothing regarding a specific database has been hardcoded
  • forms for inserting and editing data are dynamically created based on the structure of the selected table

Implementation

The main problem was how to display proper table and column names in the application. For example, I didn't want to display column "hall_id" as "hall_id" but as "Hall ID". I took advantage of column comments to solve this.

Each column in database has a comment which is displayed as column header in the application:

ALTER TABLE hall MODIFY hall_id INT(11) COMMENT 'Hall ID';

Each table in database has a comment which is displayed as the table name in the application:

ALTER TABLE hall COMMENT = 'Halls';
