Data

Data and its supporting technology stacks and architecture can be divided into two major categories:

• Operation Data

• Analytical Data

Operation Data

• These are data that supports running the business and keeping the current state of the business. This is also known as transactional data.

• Operational data is constantly updated by multiple people at the same time in an unpredictable sequence and thus are usually transactional in nature.

• It records what happens in the business, supporting decisions that are specific to business transactions.

Analytical Data

• Data warehouse or data lake which provides a historical, integrated and aggregate view of data created as a by-product of running the business.

• It is used to train machine learning models that then make their way into operational systems as intelligent services.
