Relational database comprises of relations. It includes set of operations to act on relations. It maintains data integrity for accuracy and consistency.
A relational database is a type of database, so in one sense there is no difference. There are various kinds of database. A relational database is one type. Others include network and hierarchical.
Relational completeness refers to the ability of a database management system to represent all relational operations and constraints. It ensures that the system can handle queries, updates, and integrity constraints effectively without compromising the accuracy or consistency of the data. Relational completeness is a key feature of relational database systems to ensure proper data management.
In a relational database, attributes are the characteristics or properties that describe entities in a table. Attributes are represented by columns in a table and hold specific pieces of data related to the entities. Each attribute has a data type that defines the kind of data it can store (e.g., integer, string, date).
Theoretical aspect: Relational database follows the relational model, which organizes data into tables with rows and columns based on primary and foreign keys. Conceptual aspect: It involves designing the database structure, including defining entities, attributes, and relationships between them. Physical aspect: This refers to the actual implementation of the database design on a physical storage medium, such as hard disks, memory, and indexing structures.
The word 'relational' in an RDBMS stands for relationships between tables (parent and child). So whenever you have information that can benefit from such a feature you would use relational database. For example, a customer places many orders and each order has items. This type of real world scenario is better represented in a database than in a spreadsheet for example.

Relational database: Relational database means a collection data stored in different tables and each table are linked together by using primary key and foreign key. In relational database, data can be accessed from one table to another without reorganising the required table. The relational database was invented by E. F. Codd at IBM in 1970.
