Study Notes
Data Structures in Computer Science
- A data structure is an organized way to store and manage data in a computer so that it can be efficiently accessed, modified, and manipulated.
Basis of Data Structures
- Data structures serve as the basis for abstract data types (ADTs), which are high-level models of data types.
Relational Databases
- Relational databases commonly use tables with indices for data retrieval.
Software Design
- Some formal design methods and programming languages emphasize data structures as the key organizing factor in software design.
Data Management
- Efficient data structures provide a means to manage large amounts of data.
Object-Oriented Programming
- In Object-Oriented programming, a class relates to data structures as a blueprint for creating objects that contain data and functions to manipulate that data.
Data Organization
- Organizing data as a record in data structures serves the purpose of storing and retrieving data efficiently.
Data Manipulation
- Data structures are programmed to store, retrieve, and manipulate data efficiently.
- Efficient data structures enable manipulation of data by providing a systematic way of storing and retrieving data.
