Study Notes

Introduction to Data Structure

Data refers to information stored in computers as files, organized systematically with fields containing records and values.
Data structure defines a scheme for organizing related pieces of information in computer science.
A data structure allows efficient storage, manipulation, and presentation of data.

Classification of Data Structures

Primitive Data Structures
- Directly operated upon by machine-level instructions.
- Examples: Integer, Float, Char.
Non-Primitive Data Structures
- More complex and derived from primitive structures.
- Form sets of homogeneous and heterogeneous data elements.
- Linear Data Structures: Store data in a sequential manner.
  - Examples: Arrays, Stacks, Linked Lists.
- Non-Linear Data Structures: Do not follow a sequential storage method.
  - Examples: Trees, Graphs.

Basic Operations on Data Structures

Create(): Constructs a new data structure.
Delete(): Removes a record from the data structure.
Insert(): Adds new records to the data structure.
Traverse(): Accesses each record once for processing items within.
Search(): Locates a record based on a given key value.
Sorting(): Arranges records in a logical order.
Merge(): Combines records from different sorted files into a single file.

Abstract Data Type (ADT)

An abstract data type consists of a set of values (carrier set) and a defined set of operations on those values.
ADTs specify data value sets and operations independently of implementation.
ADTs serve as mathematical models for classes of data structures with similar behaviors.
