  4. Maps are the most popular type of data visualization Everything

    happens somewhere ! Where are your clients? IP=location ! So everything can be analyzed and visualized on maps
  5. Making maps is hard because… Tools are not there yet.

  7. Most people don’t need Big Data technologies But when you

    can’t…. when it really explodes… You just need to start collecting and analyzing data. Don’t focus on technology, probably your database can already do it ! You are not Facebook, don’t be cheat
  8. Foreign Data wrappers Connect PostgreSQL to almost anything Oracle Hadoop

    MySQL MongoDB CouchDB Redis …. Twitter Email S3
