What are the key differences between an information model and a data model, and how do they impact the overall design and structure of a system?
An information model focuses on the organization and relationships of data within a system, while a data model specifically defines the structure and format of the data itself. The information model guides how data is stored and accessed, while the data model dictates the specific attributes and relationships of the data. These models impact the overall design and structure of a system by ensuring data consistency, accuracy, and efficiency in data management and retrieval.
2 Explain why navigation is simple in Relational Data Model than in Hierarchical?
Navigation in the Relational Data Model is simpler than in the Hierarchical Data Model due to the relational structure of tables linked by common keys. In the Relational Data Model, data is organized into tables with rows and columns, allowing for easy querying and retrieval of information using SQL queries. On the other hand, in the Hierarchical Data Model, data is organized in a tree-like structure with parent-child relationships, making navigation more complex and requiring traversal of multiple levels to access specific data points.
What is the difference between data model and database model?
