Data entity and function matrix: who creates, reads, updates, deletes

Six data entities run down the side and six business functions across the top. Each cell carries C, R, U and D marks showing which function creates, reads, updates or deletes the entity, with one creating function per row.

Data entity and function matrix: who creates, reads, updates, deletes A Data Entity/Business Function Matrix, the TOGAF artifact at the boundary of Phase B and Phase C, worked for London Grid Distribution. Six data entities run down the side and six business functions across the top. Each cell holds C, R, U and D marks for create, read, update and delete. Every entity has exactly one creating function, and the emphasised Customer row shows personal data never reaching the publish network data function.

Two rows carry the lesson. Capacity measurement is created once and never updated, because telemetry is evidence. Customer is the only entity that never reaches the publish column: personal data stays out of open data by design, and this matrix is where that is checked.

At the Phase B to C boundary, to fix create ownership per entity before application data design begins.
