Study Notes
Data Structures in Computer Science
- A data structure is a way to organize and store data in a computer so that it can be efficiently accessed, modified, and manipulated.
- Data structures provide a means for:
- Efficient data storage and retrieval
- Efficient data manipulation and modification
- Efficient data transmission and communication
Data Retrieval in Relational Databases
- Relational databases commonly use SQL (Structured Query Language) for data retrieval.
Key Organizing Factor in Software Design
- Some formal design methods and programming languages emphasize data structures as the key organizing factor in software design.
Applications of Data Structures
- Data structures can be used to organize the storage and retrieval of information in various areas, including:
- Computer systems
- Databases
- File systems
- Networks
