Explanation:
Detailed explanation-1: -Big data databases store petabytes of unstructured, semi-structured and structured data without rigid schemas. They are mostly NoSQL (non-relational) databases built on a horizontal architecture, which enable quick and cost-effective processing of large volumes of big data as well as multiple concurrent queries.
Detailed explanation-2: -Summary data is generated by the warehouse manager. It updates as new data loads into the warehouse. This component can include lightly or highly summarized data. Its main role is to speed up query performance. Raw data is the actual data loading into the repository, which has not been processed.
