This diagram shows an example of the structure and naming in OOP. What is data abstraction in a DBMS? Data abstraction is also used with databases to hide the underlying complexities of how the data is stored and managed. The view of the data that users have is much different from the wa...

Therefore, the process of reading and writing customer data is tedious. Instead, the following customer entity can be designed to encapsulate the entire underlying physical schema into a single de-normalized view. This enables simpler read and write operations, and enables abstraction of any internal...
Data attributes will have datatypes with exact precisions and length. Normalization processes to the model is applied typically till 3NF. Physical Data Model APhysical Data Modeldescribes a database-specific implementation of the data model. It offers database abstraction and helps generate the schema...
and interpretation of values of data. It is alogicaldata model because it does not define the physical structures in which the data may be stored in files or databases or transmitted between service units—these simply reflect technical design considerations. An LDM is a business abstraction of ...

A data entity is an abstraction from the physical implementation of database tables. For example, in normalized tables, a lot of the data for each customer might be stored in a customer table, and then the rest might be spread across a small set of related tables. In this case, the ...
