Report production in object-oriented computer systems

摘要

In response to a user (6) requesting printing/viewing of a report selected from a list of report type options, a respective object (7, 10) provides the appropriate document template (9) for the report type and provides the data required for insertion into the template from a table (8) of a database object (5), which also includes a database (4). The business objects (1, 2, 3) provide the data stored in the database (4). The data required for a particular report is extracted into the table (8) from the database (4). Previously printed/viewed reports can be reprinted/reviewed by identifying them in the table (8), but new table entries are required to be generated for reports not previously printed/viewed, and if necessary additional data can be sought from the business objects (1, 2, 3). The template with the inserted data is presented as a printed or viewable document in dependence on the selected option.
