I read that there exists three main types of databases
* Transactional (Client-Server database// OLTP database) * Decision support system (DSS) (Data warehouse database // Data mart // Reporting database) * Hybrid
What is the type of database considered for a social network, like Facebook or Twitter?
I guess the category is:
Transactional > Client -Server database.
From the book:
A transactional database is a database based on small changes to the database (that is, small transactions).The database is transaction-driven. In other words, the primary function of the database is to add new data, change existing data, delete existing data, all done in usually very small chunks, such as individual records.
But, as I said, I am not sure.
