OpenXava for teaching

The Iscte, University Institute of Lisbon, a Portuguese public higher education institution has used OpenXava within the course of design and development of information systems of the graduation degrees in Computer Science Engineering and in Computer Science and Business Management. About 200 students designed and specified the front-end and the back-end of a credit management information systems application, with a focus on a simulation and approval management module. The design phase was achieved using Business Process Modeling language and Unified Modeling language. The implementation phase involved creating databases and stored procedures in MySQL and all programming in OpenXava.

When we asked Francisco Guimaraes, teacher from Iscte about his experience with OpenXava as teaching tool, he said:

"I'm using [...] in my teaching to 255 university students to illustrate the concept of Low-Code and JPA. The experience was good until now. and the support documentation is very good."

From COBOL to Java with OpenXava

Software Promotions, a software company based in South Africa has migrated their legal accounting system from a COBOL legacy system to a Java web-based system using OpenXava. Lawpac is a comprehensive legal accounting system designed for the legal profession. The software provides the legal fraternity with the latest technology and features thereby enabling attorneys to manage their practices efficiently.

When we asked Medasha Govender, project manager from Software Promotions, why they chose OpenXava, she says:

"We migrated from a legacy system. There was a lot of code to convert. As OpenXava was model driven it allowed for rapid development. Also, we found it easy to learn and the support of the product is excellent."

When we asked her about the legacy system she says:

"It was written in COBOL using Vision files. That is why I sometimes struggle with Java. I have 20 years of experience writing COBOL applications and suddenly had to learn Java. Openxava made it a lot easier, so thank you."

Potable water in Ecuador

In Ecuador in rural areas there are companies that produce potable water, which are called water boards. A system developed with OpenXava is in production that bills and collects the potable water consumption of the inhabitants of the Olón commune in the province of Santa Elena.

The application manages the commercialization of potable water. The company has water wells that process it for distribution and sale to the inhabitants.

The system includes the following options:

  • Registration of the meter installation contract.
  • User registry.
  • Registry of facilities.
  • Meters.
  • Reading record.
  • Billing of consumption and installation of meters.
  • Collection of consumption and installation of meters.
  • Cuts and reconnections.

When we asked José Andrade, the developer behind this application, why he chose OpenXava, he says:

"Because it is an excellent tool, which significantly reduces development time, and above all things keep the database consistent with the application."
