In Relational database Data is stored as record types and the relationship is represented by set types
19.
In Hierarchical database to get to a low-level table, you start at the root and work your way down the tree until you reach your target data.
20.
Using relational model we design conceptual database design
21.
Conceptual data model is the source of information for logical design phase
22.
Logical database design describes describes base relations, file organizations, and indexes that are used to achieve efficient access to data.
23.
Conceptual data modeling uses a high level data modeling concept of E-R Models
24.
Tables are required to have at least one column
25.
Logical data independence: Refers to the separation of the external views from the conceptual view
