James works as a Database Administrator for DataOneWorld Inc. The company has a SQL Server
database. James has been assigned the task to store information for each object in the database.
Which of the following steps will help him accomplish the task?

A.
Identifying the information for objects

B.
Object modeling

C.
Object identification

D.
Identifying the relationships between objects

Explanation:
Identifying information for objects is the fourth step in database planning where the information for
each object is stored. In a table, there are
four columns that contain different types of information for objects:
1.Categorical column: In this column, data is classified and grouped, and a limited selection of data is
stored.
2.Relational or referential column: In this column, a link is established between information in one
table and related information in another table.
3.Identifier column: In this column, each item stored in the table is identified.

4.Raw data column: In this column, tangible information is stored and is determined by a source that
is external to the database.
Answer D is incorrect. Identifying relationships between objects is the last step in database
planning, which is the ability to relate
information about various items in the database. Isolated types of information can be stored
separately, but the data can be combined
according to the requirements of the database engine. Identifying the relationship between objects
in the design process necessitates
looking at the tables, determining how the tables are logically related, and adding relational columns
to the tables that establish a link from
one table to another.
Answer B is incorrect. Object modeling is the third step in database planning in which objects are
identified in the system. A user
should record an object in such a way that it is represented visually in the system. He can use the
database model as a reference during
implementation of the database. Database developers use tools such as pencils, paper, word
processing etc., as well as create software
programs for data modeling of the database.
Answer C is incorrect. In the object identification process in database planning, it is necessary to
identify the key objects or entities for
database management. There are generally a few primary objects, and once these are identified, the
related items become visible.
