2. It was a warm summer evening in ancient Greece, when
   one of the greatest philosopher of all times(guess who? :)
   gave birth to the Theory of Forms, greatly contributing to
   Ontology, eg the study of the nature of being, existence or
   reality as such.

3. An entity(from greek εἶναι, “to be”) may be defined as a
   thing which is recognized as being capable of an
   independent existence and which can be uniquely
   identified. An entity is an abstraction from the
   complexities of some domain. When we speak of an
   entity we normally speak of some aspect of the real
   world which can be distinguished from other aspects of
   the real world.

   screw vol. 666”: there must be a better solution!

8. Introducing MongoDB
   • Document oriented
   • schema-less
   • json-style
   • Scalable
   • sharding
   • replica sets
   • Performant
   • Fully featured
   • indexes
   • queries
   • map/reduce
   • gridfs
   • geospatial functions
   • capped collections
   • journaling

10. Oh noes! Philosophy again!
    Flexibility Power
    Ease of use
    Speed/Scaling
    JSON documents provide a
    schema-less, rich data
    model that maps to native
    programming language
    types
    A consistent set of RDBMS
    features implemented such
    as secondary indexes,
    dynamic queries, sorting,
    upserts, aggregation plus
    his own ones such as gridfs
    and map/reduce
    Embedded documents help
    avoiding heavy joins, while
    auto sharding makes quick
    and easy to scale out the
    database
    Installing, configuring,
    maintaining and using
    MongoDB are all kept as
    easy as possible: more time
    for your app, less for your
    server configuration
