There are three types of index data structures: unique, non-unique, bitmap
Integer (signed or unsigned)
AnswerStructure Is an Collection Of Different Data Types.

Not necessarily. A table of structures can store a variety of data types provided the structures themselves are of the same type.
A structure is not a data type. We use structures to define new data types (user-defined data types). If we didn't have the ability to create user-defined types we'd be limited solely to the built-in data types and arrays of those types.
In c language data types are used to specify the tye of data.for ex:int a;It means "a" is a variable of type integer.There are two types of data types in c.They areprimary data typessecondary data typesprimary data types are the built in data types and secondary data types are the user defined data types.eg for primary data types are int,float,char,long,double..and for secondary are arrays,structures,pointers,unions..
Programmers have to declare various data types while coding in order to inform the computer how to handle them. The types include numbers, arrays, characters, booleans and structures.
Index is a data structure that improve the performance of data.
You seem to have lost your text book so I am giving you a link where you can study data types, including derived data types.
The data structures are user defined data types specifically created for the manipulation of data in a predefined manner. Examples of data structures would be stacks,queues,trees,graphs and even arrays(also reffered as data structure)
In Pascal, data structures are implemented with recorddata types. A record is synonymous with the structdata type in C, or the class data type in C++.
1) Logical data structures are structures that emphasize on data relationships and how data is related from the view of the user. 2) Physical data structures are data models that emphasize on the use of efficiently and effectively storing data in memory.
