Data structure
Data structure
A format for organizing and storing data in a computer's memory, enabling efficient access and manipulation.
Relationship between ADT and Data structure
Relationship between ADT and Data structure
An abstract data type (ADT) defines the logical properties and operations of a data structure, while the concrete implementation of an ADT is handled by a specific data structure.

Study Notes
Definition of Data Structure
- A data structure is a way to organize and store data in a computer for efficient access and modification.
- It allows for the representation of data in a specific format according to the designed algorithms.
Relationship Between Data Structures and Abstract Data Types (ADT)
- Abstract Data Types (ADT) define a model for data structures by specifying the behavior and operations, without focusing on data representation.
- Data structures provide concrete implementations of the concepts described by ADTs.
- ADTs enable the choice of suitable data structures for various applications, emphasizing encapsulation and abstraction.
Data Structures in Relational Databases
- The most common data structure used in relational databases for data retrieval is the B-tree.
- B-trees support efficient searching, insertion, and deletion, making them ideal for database indexing.
Main Purpose of Data Structures
- The primary purpose of data structures is to enable the organization, management, and storage of data efficiently in computing.
- They facilitate the execution of algorithms in various applications by optimizing space and time complexity.
Characteristics of Data Structures
- Common characteristics include:
- Organized data representation
- Support for operations (e.g., insertion, deletion, searching)
- Efficient use of resources
- Important to identify aspects such as real-time access or dynamic resizing that are NOT considered characteristics.
