# ERP and historical data

It is not a good practice to live-query application databases with BI tools or Salesforce Connect integrations:

* Live-queries place unpredictable and overwhelming workloads on the database
* Database contention will affect the performance of the application
* Application data structures are not immediately consumable for reports or related lists

Omnata connects to cloud data warehouses that are designed to handle the workloads created by live and concurrent queries of CRM users.

The most robust architecture for live integration of ERP or historical data is to replicate and model raw data to a cloud data warehouse and connect directly to this with Omnata.
