Detailed explanation-1: -The data to be captured in a project is known in advance and is not expected to change. For example, the project may involve collecting information about a specific list of items which have common attributes.
Detailed explanation-2: -A database schema defines how data is organized within a relational database; this is inclusive of logical constraints such as, table names, fields, data types, and the relationships between these entities.
Detailed explanation-3: -Does NoSQL have a schema? NoSQL databases do not have a schema in the same rigid way that relational databases have a schema. Each of the four main types of NoSQL database has an underlying structure that is used to store the data.
Detailed explanation-4: -Relational databases provide a store of related data tables. These tables have a fixed schema, use SQL (Structured Query Language) to manage data, and support ACID guarantees. No-SQL databases refer to high-performance, non-relational data stores.
