Airtable is a powerful database platform that allows you to store, organize, and connect large amounts of data. One of the key features of Airtable is the ability to link related records across tables, creating connections between different pieces of information. This allows you to build complex relational databases that reflect the relationships in your real-world workflows.

Why Link Records
There are several benefits to linking records in an Airtable database:
- Avoid duplicate data entry: Linking allows you to store common information in one place instead of having to re-enter it repeatedly. For example, you can store client details in one table and link client records from other tables.
- Get a unified view of related information: Linking gives you the ability to view and report on connected data across multiple tables. For example, linking projects to clients lets you see all projects for a particular client.
- Simplify workflows: Linking streamlines workflows by eliminating the need to manually search for and assemble related information from separate spreadsheet-style tables.
- Enforce data integrity: Linking records establishes defined relationships, ensuring common information stays in sync and preventing orphan records.
- Build powerful applications: Linking unlocks advanced Airtable features like linked fields, rollups, and automations that can turn an Airtable base into a custom application.
Linking Methods
There are two primary methods for linking records in Airtable:
1. Linked Records Field
The linked records field allows you to form connections between records across tables. To create one:
- Add a new field to a table
- Select the
Link to another recordfield type - Choose the table you want to link to
- Airtable generates a field to store links to records from the selected table
You can then open the field and use the record picker to choose which records you want to associate.
2. Lookup Field
A lookup field pulls data from a record in another table into the current table. For example, you may have a Client Name lookup field that displays the name from a linked client record.
To create a lookup:
- Add a field
- Choose the
Lookupfield type - Select the table and field to lookup values from
- Airtable populates the lookup field with values from the linked records
Lookups create a one-way data reference while linked records make a two-way association.
Linking Best Practices
Here are some tips for effectively using linked records in an Airtable database:
- Map relationships ahead of time: Planning out the connections between records ensures your database has the right structure.
- Link tables, not bases: Linked records only work between tables in the same base. You may need to consolidate data from multiple bases into one.
- Watch field types: Don’t use automatic field types like numbers/formulas in linked fields since values can shift.
- Use junction tables: Add an intermediary table between two indirectly related tables instead of creating complex multipart relationships.
- Utilize linked fields: Link table data into another table’s fields using lookups, counts, or rollups to create summarized views.
- Leverage automation: Build automations using linked records to automatically copy/sync data, calculate values, send notifications, and more.
Real-World Examples
Linked records open up game-changing possibilities for Airtable power users. Here are just a couple examples:
- Sync data from an external CRM tool into Airtable to create a customized sales database using linked records, lookups, and automation.
- Build an employee directory linking profiles, departments, locations, and even documents like resumes and contracts. Associate employee records to various projects they work on.
The ability to define and leverage connections between records is what sets Airtable apart from traditional spreadsheets. Following linking best practices will help you build a truly relational database that supercharges your team’s workflows.
