Excerpt of article text...

The ability to share data is a useful feature to have in a personal health solution. Data is shared in one of two ways: through an external data file or through the network. Today's article looks at the first approach.

I start by describing the benefits and challenges of sharing with external files. I introduce four file formats, show how each one holds and arranges the data items. Then I design two data models, one for exporting health data, another for importing it.

Readers need a working knowledge of REALbasic and object-oriented design. Latest version of the FooHealth demo project is available from the magazine's website.

Reasons To Share

Sometimes, user-patients share some of their health data with their primary care providers. Perhaps they want to alert the provider to an ailment. Perhaps their medication is not working or is causing more problems than it is worth.

Sometimes, it is the providers who asked for the health data. Perhaps they need the data to assess their patient's progress. Perhaps they like to check on a drug's efficacy (or identify its side-effects). Or perhaps they just need to update the patient's history.
