Examples of relational database and non relational database in real world?

When would you want to use a relational database?

You would want to use a relational database when working with structured data that requires complex queries, relationships, and transactions. Relational databases are suitable for situations where data integrity is crucial, such as in banking systems, e-commerce platforms, or human resource management systems.

What is a relational database query and Explain with an example?

A relational database matches data by using common characteristics found within the data set. The resulting groups of data are organized and are much easier for many people to understand.For example, a data set containing all the real-estate transactions in a town can be grouped by the year each transaction occurred, the sale price, a buyer's last name and so on. Such a grouping uses the relational model (a technical term for this is schema). Hence, such a database is called a "relational database."The software used to do this grouping is called a relational database management system (RDBMS). The term "relational database" often refers to this type of software.Relational databases are currently the predominant choice in storing data like financial records, medical records, personal information and manufacturing and logistical data.

Which database is most suitable for small and large organization rational or object?

There is ONLY one type of database that is underlain by sound mathematical theory (Relational Calculus/Algebra see related link below) by means of which you can prove theoretically that the database works and that operations across it are true and valid. That database is the Relational Database. It would be incorrect for an organization to trust its data to ANY database that was not provably correct (if something was to go wrong the directors could be sued for choosing a database where they could not prove it was sound). Therefore the choice would have to be to place the company data into a Relational Database. An object oriented database could be used ONLY if it was implemented in/on a underlying Relational Database engine/platform (which is possible). Further, while object databases have acquired a niche in application areas such as engineering and spatial databases, telecommunications, high energy physics, molecular biology, in embedded use in devices and in real-time systems (where the requirement for data storage and retrieval is constrained to specific, narrow tasks and where speed is essential, I know of no implementation where an object database is used for corporate/business information.

History of rdbms?

1970 - In 1970, Edgar Codd, an IBM computer scientist, wrote a number of papers which developed the idea of a new form of relational database which went beyond the then current hierarchical and network database models. Codd's paper was instrumental in the development of IBM's prototype relational database known as System R (and ultimately in the development of IBM's DB2 database), as well as Oracle, the first commercial relational database1979 - Later in 1979, it was renamed Relational Software Inc and finally it was renamed Oracle. Prior to this Ellison was inspired by the paper written by Edgar F.("Ted") Codd on relational database systems named "A Relational Model of Data for Large Shared Data Banks.
