The SCANNELL system is structured into three independent tiers to allow maximum flexibility and future proofing.
1. The first tier is the presentation layer or graphical user interface. This layer utilises a standard internet browser to allow users to obtain information and carry out various activities using the system without installing any software on their local PC or device:
Internet Explorer 9+,
Google Chrome,
Apple Safari,
Firefox
2. The middle tier is the business logic layer which handles requests from users, interprets these requests in terms of the logic of the system and retrieves data from the database. This middle layer is written using the Java language.
3. The bottom tier is a relational database where all the information is stored. Data is stored using standard SQL technology (Oracle’s MySQL or Microsoft SQL Server)
All three layers are contained within a standard Web Application Server (Apache Tomcat) which provides a framework for the processing of information.
The system can be run on a number of different operating systems - Windows, Unix, etc.
The system can be installed within an organisation’s own IT environment or can be hosted in the cloud (Software as a Service or SaaS).
