,Extensions of Relational Codd’s Algebra and DB Category, we show that the computational power of the . category (used as denotational semantics for database-mapping programs) is equivalent to the .. relational algebra, which extends the .. algebra with all update operations for relations, and which is implemented as SQL statements in the software program起皱纹 发表于 2025-3-28 21:34:35

Operational Semantics for Database Mappings, initial algebraic semantics introduced in Chap. . for the syntax monads (programming languages), and completed in this chapter) of the database-mapping programs. We introduce an observational comonad for the final coalgebra operational semantics and explain the duality for the database mapping progarchetype 发表于 2025-3-29 04:53:40
