Crystal Reports require database drivers for connecting to the data source to access data. For this purpose, it supports two techniques to access data from the data source:

  2. Push Method: In this method, the developer write the code for connecting to data source and get the data. Multiple crystal reports access the data from data-set. Performance can be optimized by using connection sharing and manually limiting the number of records that are passed on to the report.

Crystal Reports Types

  • Strongly-typed style: When any report file is added into the project it becomes a strongly-typed report.
