The tab now runs write, read, curate, derive, train before it reaches the management side: Ingestion, Semantic Search, Data Curation, Feature Engineering, Training, then Management and Operations. Indexing joins Operations, where the index maintenance page already was, and gains it as Build & Repair. Ingestion gains a Create Table page. It was a section inside the overview, so the one thing a new reader needs first was the one thing the sidebar did not show. Data Curation is new: Aggregate, Sampling, Join, Windowing. The SQL reference answers what the syntax is; these answer why you would reach for it, framed as the questions curation actually asks -- what do I have, what can I afford, what else do I know, which one do I keep. Each links to the reference for the complete grammar rather than repeating it. They carry the things a reference page would not: that count(*) minus count(col) is your coverage, that sampling both sides of a join gives a percent rather than ten, that a window ordered by a value you recompute moves rows between train and test, and that a one percent sample tells you about the head and nothing about the tail.
