Hi Rajat Are you using Bonita Studio or is Bonita Hosted on a Application server ? for Bonita Studio, you can use any Database access tool. Personally I use Dbeaver to access local database. You can also use SQL Developer. you need to create connection string to access your database and tables. Bonita has 2 databases. Schema DB and Business Data. I will look it up but usually to connect to Business Data, you need  hostname is localhost , username is Sa , there is no password and db name is business\_data.db hope this helps   ---

Note that the Bonita Server embedded in Bonita Studio should only be used for testing purpose. It was not designed to allow customization of the database connection for the Bonita Engine and BDM database schemas. You can safely do your test in the Studio and setup a separated test server (using for example Tomcat+Bonita bundle or Bonita Docker image) and configure this server to use a PostgreSQL database. On another hand you might also want for example to use MySQL as DBMS for Bonita Engine and BDM database but read and update data store in a PostgreSQL database from your process. To do so you should use connectors and maybe also REST API extension. ---

Can you share (using Google Drive, Dropbox…) your project exported as a .bos file? Also note that I recommend to use the Business Data Model (BDM) feature to manage your process data. It’s a lot easier to display and edit business variables managed by the BDM as this feature is well integrate in the Bonita solution. Getting data from an external database not managed by Bonita (and updating it) is a little bit more complex and requires usage of REST API extension and connector.
