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 play a crucial role in managing data, as they enable efficient storage, retrieval, and manipulation of data.
Importance of Data Structures
- In relational databases, indexed data structures such as B-trees or hash tables are commonly used for efficient data retrieval.
- Efficient data structures are key to designing efficient algorithms, as they reduce the computational complexity and improve the performance of the algorithm.
Formal Design Methods and Programming Languages
- Some formal design methods and programming languages emphasize the use of data structures to model the problem domain, ensuring that the software design is modular, reusable, and maintainable.
