Situations in which organisations call me on Stef Joosten

Nobody oversees our spreadsheets any more

Whoever keeps a spreadsheet has thought about their reality. That knowledge is my starting point. From the data that already exists, I capture the concepts, the relations and the rules in a schema, and the register system comes from that schema.

We process every change in the law by hand

Mon, 01 Jan 0001 00:00:00 +0000

In a spreadsheet, a rule lives in the head of whoever maintains it. In a register system, it lives in the schema, as a rule about the data. An entry that conflicts with that rule is made visible by the system at once. When the law changes, the rule in the schema changes, and the system points out the data that no longer comply.

We want a register that guards its own rules

Mon, 01 Jan 0001 00:00:00 +0000

The schema of the register names the concepts, their relations and the rules that must always hold. The register system itself comes from that schema. So the register guards the rules that are in the schema, and no others.
