What two courses of action are available to a designer when encountering a multivalued attribute? Solution ANS : The two courses of action are available to a designer when encountering a multivalued attribute are going to explain briefly as follows The designer can split the multivalued attributes into its components and keep these components in the same entity.The designer may also create a new entity composed of the multi-valued attribute\'s components and link this new entity to the entity in which the multi-valued attributes occurred originally . The second option is especially desirable when the number of outcomes in the multivalued attribute is for all practical purposes unlimited. for example : employees classified as \"technical: may have certifications in many different areas and at many different levels. A multivalued attribute is an attribute in an entity that can contain multiple values . This is in contrast to single - value attributes that contain a single value. An example of a multi-value attribute is the \"hobbies\"attributes for an \"employee\" entity . It is expected that an employee can have more than one hobby. Multivalued attributes are attributes that can have many values for a single entity. Ways to handle multivalued attribute in a database design are : each of the possible outcomes is kept as a separate attribute , the additional attainments may be kept as a single , variable - length string or character field, or create a composite entity that links the two attributes. database designer have two approaches available when dealing with multi-valued attributes. The first. and simplest approach is t simply put all of the values in a single field , separated by a delimiter. continuing with our \"hobbies\" examples we can create values like : \"biking , fishing , reading \" or \"dining , riding\" . The appeal using this approach is that it is simple and requires no additional data base structure.This is called the two courses of action are available to a designer when encountering a multi-valued attribute. .

1. What two courses of action are available to a designer when encountering a multivalued
attribute?
Solution
ANS : The two courses of action are available to a designer when encountering a multivalued
attribute are going to explain briefly as follows
The designer can split the multivalued attributes into its components and keep these components
in the same entity.The designer may also create a new entity composed of the multi-valued
attribute's components and link this new entity to the entity in which the multi-valued attributes
occurred originally .
The second option is especially desirable when the number of outcomes in the multivalued
attribute is for all practical purposes unlimited.
for example :
employees classified as "technical: may have certifications in many different areas and at many
different levels.
A multivalued attribute is an attribute in an entity that can contain multiple values . This is in
contrast to single - value attributes that contain a single value.
An example of a multi-value attribute is the "hobbies"attributes for an "employee" entity . It is
expected that an employee can have more than one hobby.
Multivalued attributes are attributes that can have many values for a single entity. Ways to
handle multivalued attribute in a database design are :
each of the possible outcomes is kept as a separate attribute , the additional attainments may be
kept as a single , variable - length string or character field, or create a composite entity that links
the two attributes.

2. database designer have two approaches available when dealing with multi-valued attributes. The
first. and simplest approach is t simply put all of the values in a single field , separated by a
delimiter.
continuing with our "hobbies" examples we can create values like : "biking , fishing , reading
" or "dining , riding" . The appeal using this approach is that it is simple and requires no
additional data base structure.This is called the two courses of action are available to a designer
when encountering a multi-valued attribute.
