NoSQL A Determine whether the following statements are true or false: 1: Aggregate-oriented NoSQL databases are often easier to distribute than a relational database because they bundle relevant data together 2: Aggregate-oriented NoSQL databases are often faster to analyse stored data than a relational database because documents are kept in an unstructured ‘data lake’ which accelerates access speed 3: Aggregate-oriented NoSQL databases are usually more space-efficient for storing the same amount of data because they are ‘schema-on-read’, so the database does not need a schema. 4: A JSON/XML document enables multi-level hierarchy in its information, which allows a document-based database to mimic the structure of an object and thus 'solve' the object-relational-mismatch-problem

Document- or key-value–style databases tend to store related data together within a single record or document, reducing the need for complex joins across distributed nodes. This data locality makes horizontal distribution and sharding more straightforward and often improves sca......Login to view full explanationLog in for full answers
