How does Crystal Reports work?
Crystal Reports is a popular Windows based report writing application which allows a developer to create reports. The applications allows you to connect to various data sources to obtain data such as SQL Server or Oracle as an example. Once you have connectivity to your data source you design your reports by adding the fields from the database which are displayed from your data source and adding them to the report. Crystal Reports also allows you to perform grouping subtotals and totals. You can also write formals to perform calculations. You can also create a subreport and the subreport into the main report and a field to the subreport with the main report. This will allow the data of the subreport to display based on the main report. More expertise is required to use these features of the reporting. This is basically how Crystal Reports works in its simplest terms.
