Storing stuff (a lot of stuff)
Photos CC by Doug Wheller / Chris Campbell / Andreas
(Many) ways to interact with data
Time matters (above everything else)

What is again?
(1) is a smart database
(2) is a rapid web application framework
(3) includes a bundle of finest Apache open source projects
(4) contains the full JSR-170 goodness
(5) teaches you RESTful web app development

(6) is recommended by your CIO*
* as soon as he gets the bill

Everything
is content!

What _______ data?
- transparent versioning
- on-the-fly “schema” update
Rules of Database
- structured query
App Aging
- full-text retrieval (incl. from within documents)
(1) All Fields Become Optional
- triggers (2) All Relationships Become
Many-to-Many
- access control on node level (3) Chatter Always Expands

Bingo!

The CRX data is ...
- content persistence in TAR files
- use cheap disks thanks to low I/O usage
even remote storage (ex: via NFS mount)
- transactional safety
- simple backup
- highly scalable with cheap infrastructure

The web is (always) read/write

Magic

Your advantage is time
(1) Implement full-text search
(2) Implement access-control
(3) Re-factor code base before release thanks to OSGi
(4) Migrate database schema
(5) Code that fancy Flash product finder
(without touching the server-code)
(Bonus) Prepare your hypertext-driven services architecture proposal
I love REST!
