Question 1 of 30

A retail company is analyzing its sales data using a column-family store to optimize its inventory management. The sales data is structured such that each product has multiple attributes, including product ID, name, category, price, and sales figures for different regions. Given this structure, which of the following best describes how a column-family store would efficiently handle this data, particularly in terms of data retrieval and storage?

It allows for flexible schema design, enabling the addition of new attributes without affecting existing data structures.

It requires a fixed schema that must be defined before any data can be stored.

It stores all data in a single table, making it difficult to query specific attributes efficiently.

It uses a relational model that enforces strict relationships between different data entities.
