How do views and materialized views differ in terms of performance and use cases?
While dealing with subtype associations, it is essential to have a conversation about the many different possibilities for database tables that are accessible.Choose the format that you want to utilize, and then debate the issues that are relevant to the layout that you chose.
Draw an Entity Relationship Diagram (ERD) based on the flat files that have been supplied. Your ERD must incorporate all the entities and attributes supplied, as well as establishing the relationships between the entities

Choose a design and talk about the issues that will develop as a result of it. Computer sciencearrow_forwardThe term attribute refers to a of a table. Your answer When we talk about the table in more accurate details, for example this field, what is its data type and what is the domain of it like integer or text, this type is called view of data. Your answerarrow_forward
- Why do we need to have a point of view in the first place? What do you mean when you say that you have a point of view? There are times when information that has been defined as part of a View Definition does not really show up as a View Description. A view allows users to insert data into a database without having to create a table or row from scratch.arrow_forwardCan the answer be done as a diagram and not the code behind the creating of the tables but the actual tables and attributesarrow_forwardDiscuss the concept of denormalization in database design.
