# Getting Started
## **Overview**
The main benefits of using the Database Extension Kit plugin are:
* management of an external data store that your site uses, such as an external relational database
* storing huge amounts of data in an effective way
* user friendly administration which fits perfectly with Umbraco UI
* Avoiding common database pitfalls in Umbraco, such as volatile data, expensive lookups on content items and content tables reindexing
Storing volatile data in Umbraco content items can lead to serious performance issues and is listed among Umbraco anti-patterns:
The best way to address this is to keep the data which is either volatile or large in quantity, in an external data store. With the Database Extension Kit, you can create an external data store based on the relational database which Umbraco already uses by extending the database with the data entities you need.
The entities are created and managed in a straight-forward and user-friendly way which fits perfectly with Umbraco UI and the user experience your administrative users already have.
This documentation is aimed at Umbraco developers and administrative users who already possess a working knowledge and understanding of Umbraco concepts.
