5. SQL – some history
• For the last decades Relational Databases
(RDBMS) ruled the Data Stores
• Object Oriented Databases (OODBMS) were
already here in 1985, when OOP started to rule
• RDBMS beat the OODBMS by far back in the 80’s
• SQL is the language used to interact with
RDBMSs

7. SQL – some history (2)
• Moore’s law is out – we can’t double the
horsepower every 18 months now
• Technology is cheap, servers are cheap, we can
scale by adding more servers instead of more
memory & more CPU
• We have more data then before, and ‘one size fits
all’ is making less sense
• Bottom line: it was just a matter of time.

11. SQL or NoSQL ?
• NoSQL is not ACID – remember this if data
integrity is managed on the data store
• All SQL data-stores support stored procedures,
but so some NoSQL data-stores
• NoSQL is easier to scale at start – architecture
doesn’t need to be deeply designed in advance
• You can always migrate data-stores + effort costs!
• Don’t use one just because it’s cool!
