Tray DB is a data access application which sits in your system tray and allows you access your data in Microsoft Access or Microsoft SQL Server. Normally, if you have an Access database MDB, you would need the Microsoft Access itself to open and manipulate the data.

Likewise, if you want to access and modify data in the Microsoft SQL Server, you would normally use Enterprise Manager or Query Analyzer. This is fine for more complex tasks but for simple tasks such as edit data in one or more tables, Tray DB is much faster and more convenient.
