Hi, We have implemented TMF 653 API to retrieve the service test results for a service line. We are also storing the data into the database for another functionality to retrieve the historic data. I wanted to know which TMF API can be used to retrieve the historic data of the TMF 653 results(single or multiple records).

Many thanks

Hello!

I think, you can use TMF630 REST API Design Guidelines Part 1 paragraph 4.4. Query Resources with attribute filtering.

For historic filtering in TMF 653 you can use startDateTime, endDateTime attributes.

If you have 2 databases (first for current operations, second for historic purposes) with replication, API endpoint for users must be same, I think.

If your question was, how copy objects from source to data warehouse, you can use filtering by startDateTime, endDateTime attributes with pagination.

You might want to look into TMF 637 (Performance Management API) or TMF 701 (Service Quality Management API) for retrieving historical service test data. If your system stores the results, a custom extension of TMF 653 could also work for querying past records.
