Release Notes
You can create database for your application with our advanced Database Designer. Understanding of database concept is needed in order to use this feature.
A database is an organized collection of data, so that it can be easily accessed and managed. When you configure your database tables, a database is automatically created for you.
A table is a collection of data within a database, organized in table format with rows and columns.
By creating data models (tables) and (optionally) configuring relationships between the tables, you design your application database. After that, you can add functions to your application that allow you to populate these databases with information.
<aside> 💡 Jitera uses classic relational databases that are fully compatible with MySQL or PostgreSQL.
