The rational storage of biological data is an ever-present issue. It is not only about large data sizes, but also about the requirement of simultaneous access to them by several scientists. For instance, a few researchers from a lab may need to work on the same data, like a set of primers or data produced by sequencing. That information has to be updated and synchronized between different users and kept in a common storage. That is what UGENE Shared Database is intended for.

To start sharing data via UGENE you need to deploy a public database server. MySQL servers are currently supported. See this paragraph for details about the required server configuration.

After that any UGENE user (who knows the correct login/password, however) can connect to the database. The connected database is shown in the Project View as a document exactly the same way as if the data were located on the local computer.

As described in this paragraph the users can have a read-only access to the database or be able to modify its content. A user with a read-only access can:

• Browse the data in the database
• Open the data in the UGENE views
• Export the data to the local computer
  

 Users with write access, in addition, can:

• Add new objects to the database
• Create new folders to order the data in the database
• Modify the folders hierarchy inside the database (using drag'n'drop)
• Rename objects and folders
• Delete existed objects
• Delete folders

All UGENE instances connected to a database constantly monitors the state of the database and shows changes, made by other users.
