Hi Wilfred.
1) Is it possible to generate PDF documentation?
Yes - all you have to do is design a report using the report designer and Aware IM will automatically generate a PDF document from your report.
2) The application must include an option to do an online payment
(before the medical advice is given), i.e. a paypal option, or a
connection to a local bank. What are my options?
You can implement payment through PayPal - please check out the Library sample application. It includes PayPal payment processing. The Library Case Study document describes configuration in details.
As far as bank payment is concerned, it depends on what payment interface they support. If they use payment via URL, then configuration will be similar to PayPal; if they use web services then you can use the SOAP channel and discover bank's services.
3) In the application there's some complex processing of rules. It's
actually a repeating sequence until a stable advice (i.e. excluding some
medicine-combinations, or replacing overlapping medicines). Is a
construction like this possible?
Yes. In Aware IM business logic is handled by a rule engine, which evaluates rules repatedly until a stable state is achieved and there are no more rules to execute. All you need to do is define a consistent set of rules to manage medicines and the rule engine will handle them.
4) What would you advice about licensing? The application will run at an
ISP. Since the application is used by companies and individuals, is a
concurrent license model the best advice?
Our licensing model is based on named user licenses, not concurrent licenses. This means that your clients will not need a license to use Aware IM-powered applications. However, you will need as many licenses as there are users who work with Aware IM within your organization (if there are others besides yourself).
