To answer this question, we need to understand what an OLTP (Online Transaction Processing) system is and how it handles data.
An OLTP system is designed to process and manage real-time transactional data. It is optimized for fast and efficient processing of individual transactions, such as inserting, updating, and deleting data. These transactions typically involve current and up-to-date data.
Based on this understanding, let's go through each option to determine the best description for the age of the data in an OLTP system:
Option A) Current - This option is correct because an OLTP system primarily deals with current and up-to-date data. It focuses on processing real-time transactions and providing immediate responses.
Option B) Projected - This option is incorrect because an OLTP system does not typically deal with projected or future data. Its main purpose is to handle current data and transactions.
Option C) Historical - This option is incorrect because an OLTP system is not designed to store or manage historical data. Its primary focus is on real-time transactions and current data.
Option D) Current and Projected - This option is incorrect because, as mentioned earlier, an OLTP system does not handle projected or future data. It primarily deals with current data and transactions.
Therefore, the correct answer is Option A) Current. This option best describes the age of the data in an OLTP system, as it focuses on processing real-time transactions with current and up-to-date data.
