Study Notes
Database Models and Concepts
- The Relational Database Model emphasizes the structure of data and its relationships within a framework, utilizing tables to represent data entities and relationships.
Network Model vs Hierarchical Model
- An important characteristic of the Network Model is its ability to allow multiple relationships among data entities, enabling more complex relationships compared to the Hierarchical Model, which features a single parent-child structure.
Object-Oriented Database Models
- Object-Oriented Database Models commonly incorporate features such as the ability to store complex data types and relationships, supporting inheritance and encapsulation akin to object-oriented programming.
DBMS Definition
- In the context of database management, DBMS stands for Database Management System, which is software that facilitates the creation, manipulation, and administration of databases.
Maturity Model in Database Development
- The maturity model is significant in database development as it provides a framework for assessing the capabilities and processes of database management, helping organizations identify areas for improvement and guide their database strategy.
