The monthly Boston Water Users Group meeting will be held this upcoming Tuesday,
March 27 at 7:00 PM in Cambridge, MA. This month we will be discussing and
demonstrating Water Database and Water Query, an extraordinarily simple way to
store and retrieve business objects. The features of this new software include:



* Transparent and natural persistence of business objects

* Natural query language in ConciseXML

o More English-like than SQL

o Does not require explicit joins

* High-performance: 5,000+ reads per second, 1,000+ updates per second

* Open source version to be available for Java, C++, and C#

* Extremely lightweight - 100KB



The following is a complete example that defines a person business object,
creates an instance that is persisted in a database, and retrieves a record via
primary key.



<biz.data person id=req/>

<person "mplusch"/>

person.of.mplusch



The following is Water Query example that returns one matching record.



<find_x where=x.id.<starts_with "m"/> max_results=1/>



Here is the same call by URL



http://localhost:8080/find_x.xml?where=x.id.<starts_with "m"/> &max_results=1



Limitations of version 1.0

* No transactional support

* Limited multi-user access

* Limited indexing

* Limited query optimization



Remember to bring your Water programs to the meetings! We provide time for users
to present or discuss their active programs and receive expert help.
