Hi! If I have a simple table, with let’s say colors or something like that, is there any reason why I wouldn’t want to use that table to form multiple connections in the same table. For instance, maybe the first connection I make is for car color and then I create a second connection from the same table that is for interior car color. It allows me to do this, but I’m just worried it’s going to trip me in the future. Thank you!
Hi @Suzanne
Using a single table for multiple connections is a valid and often beneficial approach in Knack. As long as you manage the connections properly and keep an eye on the potential issues mentioned below, you should be able to use this setup effectively without running into significant problems in the future.
Using the same table ensures that your colour data is centralised. Any updates to the colour list are reflected everywhere the table is used.
Having a single table reduces redundancy, making it easier to manage and update your data. The same set of colours can be reused across different connections, reducing the need to duplicate data.
When creating multiple connections to the same table, ensure that each connection has a clear and descriptive name to avoid confusion.
For example, name the connections car_colour and interior_car_colour.
While not usually a concern for smaller datasets, multiple connections can potentially impact performance if the dataset grows significantly.
With multiple connections, be aware of the increased complexity in maintaining relationships and ensuring data integrity. Ensure you have a good understanding of how your connections interact.
Consider having a separate Colours table and linking it to other tables that need a colour as a connected object may be a better approach, depending on your setup and structure. This method brings several advantages, particularly in terms of normalisation, data integrity, and ease of maintenance.
Summary
While using a single table with multiple connections to itself can work, centralising related data in dedicated tables often results in a more maintainable and flexible database structure.
Happy to connect and take a look at your setup to see if I can help.
The below article shows a very regular use case for connecting an object to itself (self referencing connection)
