Business records (data sets)
Business records model the data definition, structure and table relationships of the data used in a form, report, or web service. Business records are designed and modified in the Business Records diagram.
Business records inherit their default information from the meta-schema from which they were created.
Reports
Business records for reports (.4rdj) contain the data definition, structure, and table relationships required to generate a data schema. The data schema is then used as input in the report design process, providing details about the data for the report designer creating the Genero report definition (4rp) file. A 4rdj file opens the Business Record diagram.
Tip: Where possible, use a single data set, gathering
multiple database tables into this data set. The database can then use a single SELECT
statement, which allows for better performance than running multiple queries. However,
multiple data sets are necessary in some cases; for example, you need multiple independent
lists of data in your reports, or your query is too complex for the database engine.
