In every organization, data is growing to thousands of records every day. It's always a challenge to fetch required data from such huge database. In SharePoint on-premise versions, there is a limit on listview of 5000 items. If you want to see items beyond that, you need to increase the limit from the administration. Even if you are fetching data from SQL database, it fetches the first 2000 items only.
So, by keeping default limits, how to get required data? Yes, we can do that. Use filters, create views with filters and sort functions. In PowerApps, we will see how to use ShowColumns, Sort and Filter functions to optimize our data fetch operations.
