A Query Domain Specific Language (DSL) is a domain specific language that facilitates the construction and execution of data queries.
- Context:
- It can (typically) be designed to simplify and streamline querying tasks by providing syntax and constructs tailored to specific data models or query operations.
- It can (often) be integrated into broader software systems, allowing seamless interaction with databases or data processing engines.
- It can (often) include features like concise syntax, specialized functions, and support for complex query patterns to enhance productivity and readability in data retrieval tasks.
- It can (often) support advanced query capabilities such as aggregations, joins, and subqueries, tailored to the specific needs of the domain.
- It can (sometimes) offer optimization features that automatically translate high-level queries into efficient low-level operations, specific to the underlying data storage or processing system.

- Example(s):
- SQL (Structured Query Language), a widely-used query DSL for relational databases.
- CQL (Cassandra Query Language) for Apache Cassandra.
- Elasticsearch Query DSL for searching and analyzing data in Elasticsearch.
- Cypher Query Language for querying graph databases like Neo4j.
