    • 1. A rubyist's naive comparison of some database systems and toolkits Marc Lainez
    • 2. Who am I ?
    • 3. Ruby on rails developer
    • 4. Agile optimist...
    • 5. The sequel world
    • 6. Object-relational mapping is a programming technique for converting data between incompatible type systems in relational databases and object-oriented programming languages. [wikipedia]
    • 7. Active record
    • 8. Active record One class, one table One object, one row
    • 9. Active record What i don’t like about it what did i map again ? migrations migrations migrations... Too much queries... (probably my fault, i’m lazy) Sometimes you have to switch to sql
    • 10. Active record What i like about it strongly bond to rails... nice documentation works with most plugins and gems... works with most sql databases
    • 11. Datamapper
    • 12. Datamapper very similar to ar
    • 13. Datamapper
    • 14. Datamapper What i don’t like about it migrations Some plugins might not work (thinking sphinx)
    • 15. Datamapper What i like about it mapping in models modular strategic Eager loading works with most sql databases faster than ar
    • 16. The NOSQL world
    • 17. NOSQL non-relational data stores that doesn’t require fixed table schemas, and usually avoid join operations. [wikipedia]
    • 18. NOSQL and ruby Document based db Mongodb couchdb ... Key/value store TOkyo redis project voldemort ...
    • 19. NOSQL and ruby mongodb
    • 20. NOSQL and ruby COUCHDB Stores documents as json easy to read, easy to parse, easy to send through a network is distributed database can exist in multiple places EAch document is a restful resource
    • 21. COUCHDB Web interface
    • 22. COUCHDB RELAXDB
    • 23. COUCHDB, ar-like Stuffing couchfoo
    • 24. NOSQL and ruby tokyo key/value store distributed (tyrant) full-text search engine (dystopia)
    • 25. NOSQL and ruby tokyo hash db one key, one value b-tree db one key, multiple values fixed-length db access via natural number keys table db mimics relational db
    • 26. Tokyo b-tree db
    • 27. The best of both worlds ?
    • 28. nosql in SQL friendly
    • 29. What do i think about all this ?
    • 30. a few links http://www.belighted.com http://datamapper.org/ http://www.mongodb.org/ http://couchdb.apache.org/ http://github.com/paulcarey/relaxdb http://github.com/paulca/stuffing http://www.google.com/search?q=couchfoo http://1978th.net/tokyocabinet/ http://friendlyorm.com/
    • 31. questions ?
