What is Data Storage?
- Methods & technologies for retaining and managing digital information
- Includes various devices and systems for capturing, organizing, and maintaining data
- Ensures efficient retrieval and processing
What is a Database?
- A collection of interrelated data
- Enables efficient retrieval, insertion, and deletion of data
- Organizes data in tables, views, schemas, and reports
What is a Database Management System (DBMS)?
- Software designed to store, organize, and manage data efficiently
- Consists of the Database (collection of interrelated data) and the Management System (ensures proper data handling)
Two Main Types of DBMS
-
Relational Database Management System (RDBMS):
- Most mature database type
- Data organized into tables with rows and columns linked through primary & foreign keys
- Popular for web-based applications and user data storage
-
Non-Relational Database Management System (NoSQL):
- Offers flexibility beyond traditional relational structures
- Enables efficient storage and retrieval of large, unstructured datasets
- Well-suited for handling large volumes of data and fast queries
Importance of Data Storage
- Preservation of data
- Accessibility
- Data backup & recovery
- Security & privacy
Importance of Database
