ObjectDB

ObjectDB (JPA-compliant pure object database for Java)

Webel now employs ObjectDB - a JPA-compliant pure-object database - as the primary database technology for Enterprise Java web application development:

For demonstrations and examples, please visit the tutorial presentations and demonstration videos of the GreenDesk web application for modelling and environmental compliance tracking of office buildings, developed by Webel for GreenSoft Pty Ltd, Australia.

Java Persistence API (JPA)

Webel employs the Java Persistence API (JPA) as the core database technology for Enterprise Java web application development in combination with JPA-compliant object-relational database mapping technologies (EclipseLink and Hibernate) for relational database management systems (MySQL, Oracle DB), as well as in combination with the JPA-compliant pure-object database ObjectDB. Core JavaServer Faces (JSF) and the PrimeFaces 3rd-party JSF GUI toolkit are used to create rich interactive web worksheets for Enterprise Java web applications from data and objects served via JPA and managed via Enterprise Java Beans employing Expert System strategies:

Developed a unique JavaEE web application GreenDesk for analysing and tracking the complex data and documentation required for preparing applications compliant with the Green Star Office sustainable building rating system of the Green Building Council of Australia (GBCA).

The system uses Expert System technology in Java as an intermediary between rich interactive web user interface worksheets and model views using JavaServer Faces (JSF), and an underlying Enterprise Java domain entity database model - the Building Project Model, created using Parsing Analysis technology to map the Green Star Office specifications to domain model elements and rules.

After initially using an MySQL database with object-relational Java Persistence API (JPA) mapping with EclipseLink, then an object-relational Oracle DB with EclipseLink, a major migration was made to a JPA-compliant pure-object database ObjectDB, with significant improvements.

The PrimeFaces toolkit for JavaServer Faces (JSF) was used to enhance the rich web user interface.

The software engineering included frequent use of graphical Unified Modeling Language (UML) for requirements and domain analysis, model-driven Java design, Java code refactoring, documentation, and even proved useful for freestyle graphics presentations for non-experts. The closely related Systems Modeling Language (SysML) heavily influenced the Building Project domain model.

Custom object-oriented PHP scripting was used to generate Enterprise Java database entity classes directly from a Drupal CMS web site entity-relational database model of the Green Star Office technical manual’s specification for the green office building rating system of the Green Building Council of Australia (GBCA). Such novel and advanced automation of coding is a speciality of Webel IT Australia.

Drupal CMS web site development: Developed a GreenSoft company web site, a web site for the GreenDesk product, and the GreenBase site for resources on global environmental rating schemes.

Prepared investor presentations and held pitch meeting demonstrations for potential investors. Demonstrations included screencast tutorial videos made using ScreenFlow.

Created 3D logos and animated 3D logos using Swift3D.
