Transcript

  • 1. Why CouchDB? the above type is not rendered in comic sans... see... Chalkboard Comic Sans MS Data Data
  • 2. Lonely Data data access depends on (often API-less) app (esp. desktop) web apps are a little better, but not always not general meant for replication/backup app may be open source, but data’s still tangled up (RDBMS)
  • 3. Enter...
  • 4. JSON Documents {“json”: “key/value pairs”, “_id” : “some uuid”, “_rev”: “mvcc key”, “string keys”: [1,2,3,”four”,null], “schema free”: “flexible”} Your programming language supports JSON! Adapt data as your application changes.
  • 5. HTTP / REST you already know the API GET read PUT create or update DELETE delete POST bulk operation
  • 6. Peer-Based Replication for Freedom triggered, incremental, filtered (soon)
  • 7. Portable Standalone Apps replicate-able apps CouchApps live inside CouchDB Get replicated with data Includes map/reduce views as well as... _show - output rendering _list - incremental index/list output _update - document validation .js, .css, .png attachments for the UI
  • 8. Let’s Replicate... ...EVERYTHING!!1! Take full advantage of CouchDB The Future is Distributed not just data, but... queries output formats attachments whole applications and everything else in between
  • 9. Imagine these as CouchApps OpenLibrary.org contribute & get updates periodically add your book while on the plane, publish it when you get off Subject Guides more ad-hoc content (thanks to schema-less- ness) more contributors (give’m their own CouchDB)
  • 10. CouchDB does replication you get to do the other stuff thanks also: check out hosting.couch.io for a free Couch
