Well just to give a generalization using an OLAP as your data model, the data is stored in a
denormalized yet defined model. Data integrety is maintained because by definition all records
inserted will remain static.
Here are some additional links that can be used for getting started:

Another alternative is to create a materialized view that will update itself only when records are
inserted or updated.
