  • A rubyist's naive comparison of some database systems and toolkits

    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/
