Study Notes
RDBMS
- RDBMS stands for Relational Database Management System, a software system for creating and managing relational databases.
Relational Model
- E.F. Codd proposed the relational model of data in 1970, establishing a framework for organizing data into tables.
Role of SQL
- SQL (Structured Query Language) is used for querying, updating, and managing data in relational database systems, providing a standardized way to interact with the database.
Term Definition
- The term 'relational database' was first defined by E.F. Codd, marking a significant evolution in database management.
Codd's Research Contribution
- In his research paper "A Relational Model of Data for Large Shared Data Banks," Codd introduced fundamental principles of the relational model, including data representation in tables, data integrity, and the concept of keys and relationships.
Database System Meaning
- A database system refers to the combination of the database itself and the software that manages the stored data, facilitating data access, manipulation, and management.
Definition of Database
- A database is an organized collection of structured information or data, often stored electronically in a computer system, enabling efficient retrieval and manipulation.
Storage of Small Databases
- Small databases can be stored on personal computers or local servers, often within applications or desktop database software.
Database Design Considerations
- Key considerations in database design include data integrity, normalization to reduce redundancy, scalability, performance optimization, and security measures for data protection.
Hosting of Large Databases
- Large databases are typically hosted on powerful servers or cloud platforms, allowing for better performance, scalability, and centralized access for multiple users and applications.
