A database management system that stores and arranges data in a hierarchical structure is known as a hierarchical database management system (HDBMS). The data organization in this structure resembles a tree; parent-child relationships are used to store the data. Each parent node in a hierarchical...

The purpose is to developed technical map of rules and data structures. Physical Data Model: This Data Model describesHOWthe system will be...
The Relational Model:The relational model provides an application with a consistent manner of describing and querying data. One of the advantages of the relational model is that it allows you to write and query data in a database using Structured Query Language (SQL). SQL is a database query...
Instead, each type of NoSQL database typically has its unique query language or API tailored to its specific data model and structure. While NoSQL databases prioritize flexibility and scalability, they often relax some of the ACID properties found in relational databases. For example, some NoSQL...
