B Correct answer
Explanation

ODS (Operational Data Store) is designed to be volatile, meaning data can be updated, deleted, or modified frequently. This volatility is what makes it suitable for operational reporting and tactical decision-making. Data Warehouses, in contrast, are non-volatile (data is not updated or deleted once loaded). The statement claims ODS is non-volatile, which is false.

AI explanation

To answer this question, we need to understand what an Operational Data Store (ODS) is and what its characteristics are.

An Operational Data Store (ODS) is a database that integrates and stores data from multiple operational systems. It is designed to support real-time or near-real-time reporting and analysis. Unlike a traditional data warehouse, an ODS is typically updated frequently and holds more granular and detailed data.

Now, let's evaluate the statement:

ODS is a Non-Volatile data store.

Option A) True - This option is incorrect. An ODS is not a non-volatile data store. Non-volatile data stores are designed to retain data even when power is lost or the system is shut down. Examples of non-volatile data stores include hard drives, solid-state drives, and non-volatile memory. An ODS, on the other hand, is a volatile data store that holds current and frequently updated data.

Option B) False - This option is correct. An ODS is not a non-volatile data store. It is a volatile data store that holds current and frequently updated data.

The correct answer is B) False. An ODS is not a non-volatile data store.
