Which NoSQL database is known for its ability to handle complex queries and data analysis ?
Answer: D
The key gives (D) MongoDB.
MongoDB is a document database. It stores records as JSON-like documents and offers a rich query language with filters on any field, indexes of several kinds and an aggregation pipeline (grouping, joining, filtering, transforming), which is what supports complex queries and data analysis on the data in place.
dBase is an early desktop database management system, not a NoSQL database. HBase is a wide-column store on Hadoop built around reads and scans by row key, with no rich query language of its own. Couchbase is the closest rival, since it offers a SQL-like query language over JSON documents, so the item is not watertight, but the key names MongoDB as the better-known answer.
