## What it is
Logica is an open-source declarative logic programming language in the Datalog family that compiles to SQL. It lets users write logic-style predicates that run on DuckDB, Google BigQuery, PostgreSQL, SQLite, Trino and Presto engines.

## Use cases
- write bigquery queries with logic programming syntax
- compile datalog rules to sql
- run logic programs on postgres or sqlite
- learn logic programming applied to data analysis
- replace complex nested sql queries with declarative predicates
- run datalog-style analytics on duckdb locally

## When to choose
- you prefer logic programming syntax over sql for data queries
- your data lives in BigQuery, PostgreSQL, SQLite or DuckDB
- you want to learn Datalog with real big-data backends
- your SQL queries have complex non-trivial logic

## When to avoid
- your team is SQL-only and won't learn a new language
- you need a SQL engine or dialect not supported by Logica
- you need mature tooling and a large ecosystem around your query language

## Facets
- artifact type: cli-tool
- maturity: active
- function: compiler, programming-language, database, parser
- domain: programming-languages, databases, data-science, big-data, analytics
- platform: python, cli, cross-platform
- tags: datalog, logic-programming, sql, bigquery, duckdb, postgresql, sqlite, prolog, query-language, datawarehousing
