What is SQL Anywhere?

SQL Anywhere is the embedded database engine SAP inherited from Sybase/iAnywhere. Its on-disk format is a fixed-size page store with B-tree indexes and a write-ahead log - well-understood in principle but never published as a spec. OpenSQLAnywhere documents the format and ships a reader so the data layer outlives the runtime.
