Data Structure is a way to organized data in such a way that it can be used efficiently. Following terms are basic terms of a data structure.
Data Definition defines a particular data with following characteristics.
Atomic − Defition should define a single concept
Traceable − Definition should be be able to be mapped to some data element.
Accurate − Definition should be unambiguous.
Clear and Concise − Definition should be understandable.
Data Object represents an object having a data.
Data type is way to classify various types of data such as integer, string etc. which determines the values that can be used with the corresponding type of data, the type of operations that can be performed on the corresponding type of data. Data type of two types −
Built-in Data Type
Derived Data Type
Those data types for which a language has built-in support are known as Built-in Data types. For example, most of the languages provides following built-in data types.
Boolean (true, false)
Floating (Decimal numbers)
Character and Strings
Those data types which are implementation independent as they can be implemented in one or other way are known as derived data types. These data types are normally built by combination of primary or built-in data types and associated operations on them. For example −
