WebDatalog is a declarative logic programming language that syntactically is a subset of Prolog. It is often used as a query language for deductive databases. In recent years, Datalog has found new application in data integration, information extraction, networking, program analysis, security, cloud computing and machine learning. [1] [2] WebMar 6, 2024 · Motivation. The syntax of Soufflé is inspired by implementations of Datalog, namely bddbddb and muZ in Z3 . There is no unified standard for the specification of Datalog syntax. Thus, each implementation of Datalog may differ. A principle goal of the Soufflé project is speed, tailoring program execution to multi-core servers with large ...

WebDatalog is a declarative logic programming language. While it is syntactically a subset of Prolog, Datalog generally uses a bottom-up rather than top-down evaluation model. This difference yields significantly different behavior and properties from Prolog. It is often used as a query language for deductive databases.

Datalog该如何入门? - 知乎
WebDatalog is a logical query language. It exists somewhere between relational algebra (the formal theory behind SQL) and Prolog, but is closer in motivation to the former than the later. It was invented to apply some of the principles of logic programming to database theory. Its primary addition to the semantics of databases is recursive queries. WebFeb 13, 2024 · fsaenzperez February 15, 2024, 10:23am 7. I think that the main difference between Prolog and Datalog is that the latter is not meant as a general-purpose language; rather, it is targeted to querying relational databases where one typically wants all solutions from a query. This also means that compound terms are not allowed because they are ...
