Questions and Answers

Explain the concept of a super column family in NoSQL databases and provide an analogy with relational databases.

A super column family in NoSQL databases contains column families and can be seen as a 'view' on a number of tables, similar to a view in relational databases.

What are the benefits of using a super column family in data modeling for distributed data stores?

It provides a way to have a view on a number of tables, similar to a view in relational databases.

How are super columns sorted and queried in distributed data stores like Apache Cassandra?

Super columns are sorted when added to the column family, and it is also possible to use a different sorting attribute for the contained columns of a super column.

Explain the limitations of sorting super columns after insertion and querying arbitrary queries in distributed data stores.

<p>There is no way to sort super columns after they have been inserted, nor to query an arbitrary query in distributed data stores.</p> Signup and view all the answers

In what way are super column families similar to a 'view' in relational databases, and how do they differ in terms of data manipulation?

<p>Super column families provide a view on a number of tables, similar to a view in relational databases. However, there are no 'joins' between the 'tables' in distributed data stores, as they are non-relational.</p> Signup and view all the answers
