www.wavemaker.com Banko Di Seguro Sosial (SVB) is a social security agency in Curaçao (A Dutch Caribbean island). The organisation has an executive function and deals with beneﬁts for insurance like health, old-age, accidents and unemployment etc.,

Client Scenario

The client operated on Microsoft stack and had The client was open to use Java and wanted to rebuild multiple internal and external .NET apps that most of their applications. were developed as an integrated system and are not web based. Usage of earlier technologies like WaveMaker was their choice of low-code platform as it Silverlight, which aren’t supported by browsers is extensible (availability of clean readable code) and today, restricted the ease of transformation to a has novendor lock-in. With WaveMaker security is web based system. baked in; it saves costs, and promotes efﬁcient They were data driven and had an internal audit development. team that exposed data as web services but due to government restrictions they had to keep their infrastructure in-house.

Database API Interface

Legacy app databases were not Duplication of common services To create a consistent look and fully leveraging RDBMS features, by multiple applications made feel for all applications, a they used stored procedures to them process heavy and slow. A common visual framework was perform business logic. Using wrapper function (API) was developed, which included WaveMaker, we seamlessly created for all common services responsive layouts, page imported this database, mapped and workflows (like login, templates, widgets, and design it, and reused business logic password reset, logout, forgot patterns. inside stored procedures. We password, email notification etc.). also customized additional To ensure robust security these workflows. APIs were made private and additionally, calls to them were intercepted to filter out sensitive user data.

02 wavemaker Work Outcomes

The database, API, and the interface together formed the core application shell. By leveraging this shell, the client can rapidly develop any applications in the future. With this shell as our base, and using the drag-and-drop visual low-code development environment of WaveMaker, we were able to transition the client’s .NET-based applications into a Java-based system at a rapid pace without compromising on application design, control, and security.

“The WaveMaker team responded very quickly to our requests. Project execution was smooth and we are very pleased with the results.”
