Software Design Principles
So far we have discussed different software architecture topics in more low-level aspects, focusing on designing specific parts of software system separately such as backend, frontend, middleware etc. With this article we take the discussion to one step further and discuss designing a software system end-to-end. In designing whole system, besides detailed technical analysis the one needs to make thoughts about scalability of a system supporting from one user to million users. The absolute must-have pillars of a system design are:
Picking a database…
Database — whenever there is a need for a persisting data continuously, there is a need for Databases.

- Non-Relational Databases (also called NoSQL databases) like MongoDB, CouchDB, Cassandra are well-known examples that are categorised in 4 different forms: key-value stores, column stores, graph stores and document stores.
