How to connect to different sources of data by selecting request type in Arnica WebReport

December 11, 2014 by Igor Lozhkin
Arnica WebReport is a two tier system: the first tier, report source, is responsible for connecting to the source of data (for example, database), discovering columns, reading records and passing both data and column information to the report,  the second tier. Report is responsible for applying presentation rules and generating HTML output. When working on report source level, designer must choose request type, which specifies how report source receives data from a remote source. 

Arnica WebReport supports the following request types:
  • ODBC - data is received from ODBC source (defined by either system DSN or connect string)
  • File - data is read from external file (for example, Excel file)
  • Posted data - data is received as posted content which is passed to the report with the same web service request, which invokes the report
  • Server-to-server web request - data is received by executing web request against another web service, optionally posting query parameters data
  • Program script - report source executes program script which may execute any other logic to derive data
  • Joined report sources - data is derived by invoking other report sources and joining or unionizing their results 
The screenshot below shows request type selection page:
