Re: You can only get away with a screw you attitude...
@boltar - Postgresql, MariaDB, and Percona as well as many others are relational databases not NoSQL. The previous comment was about replacing Leisure Suit Larry with another relational database rather than with a NoSQL database. The replacement, while not trivial, is fairly straightforward as the tables often can be replicated with minimal fuss. What will be a pain is converting the queries, views, etc from one SQL dialect to another; doable but no one's idea of a fun project.
My observation about database types is relational generally will work with most data sets at least tolerably well and they are well understood. NoSQL, however, are either the ideal solution to the problem or a real dog and often properly setting them up for optimum performance is not well understood particularly if one tries to use relational modelling on them.
