Title: Lightweight data management patterns

Hi,

Firstly, let me introduce myself. I work for Siemens Communications in the UK on a VOIP phone development, and have been interested in patterns for a few years now. My colleagues and myself are currently developing a new software architecture, part of which is the identification and selection of appropriate patterns.

The reason I'm posting today is to ask a question - if this isn't the right place for such questions, any pointers to forums or mailing lists etc where I might be able to find an answer would be appreciated. I haven't been able to find much on the 'net so far that matches what I'm looking for, so any help would be great.

In a nutshell: I'm looking for "Lightweight data management" patterns.

By this, I mean patterns that allow for management of data in an resource restricted, real-time environment. The data may be stored in flat files, or alternatively a lightweight database such as SQLite.

Additionally, a number of data management requirements have been identified - so any patterns you have in mind should ideally not conflict with the following list :-)

- Fast data access
- Single point of access (programmatically)
- Simple, easy to use interface
- Access control
- Data profiles
- Data Location transparency
- Caching
- Change notification / Replication

So far, I've identified a number of potentially applicable patterns:

Proxy (GOF - to control access to data management services)
Observer (GOF - for change notification)
Strategy (GOF - to provide different data access algorithms)
Lookup (POSA 3 - to provide part of location transparency)

So if you are able to add to the list of patterns that we should be considering, please get in touch.

Kind regards,
