Introduction to Database Triggers in Serial

Database triggers play a crucial role in maintaining data integrity, automating processes, and enforcing business rules in the Serial codebase. These triggers are SQL functions that are automatically executed in response to specific database events, such as insertions, updates, or deletions. In the Serial system, we have identified several triggers that handle various aspects of data management. While detailed information about each trigger’s specific functionality is not available, we can provide an overview of the triggers present in the system.

​
List of Database Triggers

The Serial database employs the following triggers:
  1. before_insert_component_process_links
  2. before_insert_processes
  3. before_insert_report
  4. before_insert_work_order
  5. before_update_report
  6. before_update_work_order
  7. check_unique_source_dataset_id
  8. checkboxes_trigger
  9. last_updated_at_component_instance
  10. parametric_qualitative_trigger
  11. parametric_quantitative_trigger
  12. process_entries_trigger_defective_wip_complete
  13. tr_update_unique_identifier_links_removed_at
  14. trigger_update_process_revision

​
Implementation Details

The exact implementation of each trigger can be found in the supabase dashboard. This is generally easier than trying to find the most recent update in the database migrations.

​
Importance of Triggers in Serial

Triggers in the Serial database likely serve several important functions:
  1. Data Validation: Ensuring that data meets certain criteria before being inserted or updated.
  2. Automatic Updates: Keeping related data in sync across different tables.
  3. Logging: Recording changes or actions for auditing purposes.
  4. Business Logic: Implementing complex business rules that need to be consistently applied.

Conclusion

The Serial codebase utilizes a variety of database triggers to maintain data integrity and automate processes. While specific details about each trigger’s functionality are not available, their names suggest a well-structured approach to database management. Developers working with the Serial system should be aware of these triggers and their potential impacts on data operations. For more detailed information about each trigger’s specific implementation and purpose, it would be necessary to consult the database schema documentation or examine the trigger definitions directly in the database.
