1. Relational Model : Newer database model; Network Model - Older database model 2. The network model structures data as a tree of records with each record can have multiple parent and child records, forming a lattice structure. The basic data structure of the relational model is the table, where information about a particular entity (say, an employee) is represented in columns and rows 3.The relational model has strong mathematical foundation with set theory and predicate logic.

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 relational schema?
A relational schema is a structure that represents the logical view or design of a database. It defines how the data is organized and the relationships between different entities or tables. It typically includes the names of the tables, their attributes or columns, and the constraints that define the relationships between them.
