A data query engine is a software tool that allows users to access and retrieve data from a database. It allows users to submit queries written in a specific query language, such as SQL, and receive the corresponding results. These results can be displayed in a variety of formats, such as tables or charts. Data query engines are commonly used in business intelligence and data analysis applications.

  5. MongoDB - An open-source, NoSQL document-oriented database that stores data in semi-structured BSON format. It is designed for scalability and high performance and is widely used in big data and real-time web applications.

  6. Elasticsearch - An open-source, distributed search engine that is built on top of the Lucene library. It is commonly used for data analysis and search functionality in big data applications.

  7. BigQuery - A fully-managed, cloud-native data warehousing service provided by Google Cloud Platform. It allows users to analyze large datasets using SQL and other big data technologies.
