what is data model?explain in detail
Answers
Answer:
A data model refers to the logical inter-relationships and data flow between different data elements involved in the information world. It also documents the way data is stored and retrieved. Data models help represent what data is required and what format is to be used for different business processes. Data models are made up of entities, which are the objects or concepts we want to track data about, and they become the tables in a database. Products, vendors, and customers are all examples of potential entities in a data model. A data model not only improves the conceptual quality of an application, it also lets you leverage database features that improve data quality. Insurers are having difficulty providing coverage because the data they receive is too often corrupted by application errors.
