A relational database is a type of database that stores and organizes data in tables with a predefined structure. The purpose of creating a database is to efficiently store, manage, and retrieve data for various applications or systems. Databases help to ensure data integrity, enable data sharing, provide a structured way to store information, and support data analysis and reporting.
SQL (Structured Query Language) is a programming language used in database management to manipulate and retrieve information. Its purpose is to interact with relational databases, allowing users to create, modify, query, and manage data efficiently. SQL is widely used in various applications and systems to store and retrieve data in a structured manner.
A database is used to organize and store information in a structured manner, making it easier to retrieve and manipulate data efficiently. It helps in ensuring data consistency, reliability, and security.
The first step in creating a database is to define the purpose and scope of the database, including identifying the data that needs to be stored and how it will be organized. This involves understanding the requirements of the system and the relationships between different data elements.
Databases are used to store, organize, and retrieve data efficiently. They help in managing large amounts of information, ensuring data integrity, and providing a structured way to access and manipulate data.
The purpose of queries in a database is to retrieve specific information or data by filtering, sorting, and manipulating the database tables. Queries allow users to extract relevant data based on specified criteria without needing to search through the entire database manually. They are essential for data retrieval, analysis, and reporting in database management systems.

It really depends on the purpose of the database. For some function relational would be better, for some manual would be. You might want to research the application you wish to incorporate.

Data redundancy is a data organization issue that allows the unnecessary duplication of data within your Microsoft Access database. A change or modification, to redundant data, requires that you make changes to multiple fields of a database. While this is the expected behaviour for flat file database designs and spreadsheets, it defeats the purpose of relational database designs. The data relationships, inherent in a relational database, should allow you to maintain a single data field, at one location, and make the database's relational model responsible to port any changes, to that data field, across the database. Redundant data wastes valuable space and creates troubling database maintenance problems

1) Database is designed and built with data for a specific purpose. 2) We can perform the operations simply on database. 3) Database provides a logical relational b/w its record and data.
