At the same time, we’ve also added additional capabilities to these editions. This is why I felt it is worth taking a moment to recap what’s the focus of each edition, who they are aimed to, and what they offer in terms of features. Professional Editio...

Secrets of FireDAC: Pagination With Grids And LiveBindings If you want to display only a range of results from a recordset you can using paging (otherwise known as pagination) to do so. It is a common pattern when doing web development to give the user 20 results for example and then the ability to move to the next page. If you are implementing a REST API in RAD Server you might also implement this functionality instead of delivering 2 million rows for the query you only deliver the first 20 rows and the next 20 can be requested in the next call. Obviou...

API Limits with #FDEC The FireDAC Enterprise Connectors (#FDEC) by CData and Embarcadero make it really easy to work with various APIs just like you would any SQL database.
