+If you work on software projects that use a database, you need a convenient way to connect, inspect, and query them.
+
+Some IDEs like PhpStorm have an integrated database client, which I've recently added to my Neovim setup and working with Docker and Docker Compose.
+
+## Configuring Docker Compose
+
+A local port needs to be exposed from the database container that Neovim can connect to.
+
+I usually do this with a `docker-compose.override.yaml` file:
+
+```yaml
+services:
+  database:
+    ports:
+      - 3307:3306
+```
+
+Docker Compose recognises this by default, extends the normal `docker-compose.yaml` file and adds a port forwarding to the `database` service.
+
+## Configuring Neovim
+
+The two plugins I'm using are tpope/vim-dadbod and kristijanhusak/vim-dadbod-ui, and should work with Vim and Neovim. Thanks to both of these project maintainers.
+
+Once installed, run `:DBUIAddconnection` to add a database connection.
+
+Here is an example connection string:
+
+```plain
+mysql://drupal:drupal@localhost:3307/drupal?protocol=tcp
+```
+
+Using the local port mapping, this connects to a MySQL database within the `database` service.
+
+Then run `:DBUI` to toggle the UI and see a list of databases in the left-hand sidebar.
+
+You can enter `<leader>R` to refresh databases or `r` to rename or update connection details for a specific database.
+
+Once connected, you can enter and save queries, using table and column name completion, which are executed every time the query is saved.
+
+I like not needing to switch contexts and leave my editor in order to query a database, and feel a lot more productive being able to write, execute and save queries within this UI.
+
+If you're a Vim or Neovim user, I'd suggest trying this setup and seeing if it works for you.
