Data Structures

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.
