(a)A hierarchical database is a type of database that organizes data in a tree-like structure, with each record having a single parent record and multiple child records. This structure is similar to a file system, where directories and subdirectories are organized in a hierarchical manner.

KEY FEATURES OF HIERARCHICAL DATABASES:

(i)Data is organized in a tree-like structure
(ii)Each record has a single parent record and multiple child records
(iii)Relationships between records are represented as links between nodes
(iv)Data is stored in a series of segments, each containing a group of related records
(v)Supports fast data retrieval and efficient data storage

EXAMPLES OF HIERARCHICAL

(i)IBM’s IMS (Information Management System)
(ii) Windows Registry
(iii) XML (Extensible Markup Language) documents

(B) A network database is a type of database that organizes data as a network of interconnected records, allowing for multiple relationships between records. This model was developed to overcome the limitations of hierarchical databases.

IN A NETWORK DATABASE:

(i)Data is stored as a collection of records, called nodes or segments
(ii)Each record has multiple parents and children, forming a web-like structure
(iii)Relationships between records are represented as links or pointers
(iv)Each record can have multiple owners and multiple members.

FEATURES OF NETWORK DATABASES

(i)Multiple relationships between records
(ii)Flexible data modeling
(iii)Efficient data storage and retrieval
(iv)Support for large-scale applications
