# appRules Embedded Database DBA Tool

If you have defined some embedded database project databases, you can edit and modify them directly using the appRules Embedded Database DBA Tool. 

{% hint style="info" %}
It is recommended that you use SQL Server, SQL Azure or other supported enterprise database engine as your project database for major projects.  The appRules Embedded Database is only recommended for small projects or for prototypes.          

You can use the appRules CheckIn/CheckOut utility to copy the contents of one project database into another. 
{% endhint %}

The DBA Tool is accessible directly from the root folder by running the executable:
