(Don’t fear) the Beaver

Apologies to Blue Öyster Cult – I couldn’t resist. The beaver is question is DBeaver. I was recently looking at a client issue and needed to import some data into a mariadb database on a hosted platform we use. This was not on my normal development machine where I would have a range of tools including heidisql to carry out the required task.

Instead I went looking to see if there was something that would let me work with the data and then potentially transfer it to another database platform once I had done some manipulation on it.

Enter the Beaver !  Having located the Dbeaver site – and created a connection to my online instance – it was trivial to get the data wrangled and give the client the results needed. The client couldn’t believe the quick turnaround !

The app claims a number of things but the three highlighted are what drew me to the app in the first place !

  • Usability is the main goal of this project, program UI is carefully designed and implemented.
  • It is free and open-source (ASL).
  • It is multiplatform.
  • It is based on opensource framework and allows writing of various extensions (plugins).
  • It supports any database having a JDBC driver.
  • It may handle any external datasource which may or may not have a JDBC driver.
  • There is a set of plugins for certain databases (MySQL, Oracle, DB2, SQL Server, PostgreSQL, Vertica, Informix, MongoDB, Cassandra, Redis, InfluxDB in version 5.x) and different database management utilities (e.g. ERD, data transfer, compare, data export/import, mock data generation, etc).
  • It has a great number of features.
