Governance upstream of the semantic layer
Looker’s central idea is worth taking seriously: define metrics once, centrally, and everyone reports the same figures. It solves a real organisational problem, and nothing in Parabola replaces it.
But a semantic layer governs definitions, not inputs. If the operational data feeding the warehouse is incomplete, unreconciled, or silently wrong — a partner file that arrived in a different format, invoices nobody matched — then the governed metric is a consistent view of bad data.
Parabola works on that upstream problem, and it applies its own kind of governance to it: every step shows its input, logic, and output, run history is kept, and row-level data tracing lets you click a figure and see every upstream row that produced it.
Which one is right for your team
Choose Looker when the problem is organisational consistency — many teams reporting the same metrics from a warehouse a data team maintains.
Choose Parabola when the problem is that the operational data is not trustworthy yet, or when what the team needs is a queue of exceptions to work rather than a report to read. A common arrangement is both: Parabola reconciling and landing clean data, Looker governing how it is reported.
