The document discusses a client modernization project where an old IBM AS/400 system managing legal professional data was replaced with a new system built using Java, HTML5, and Angular on WaveMaker. WaveMaker helped with database redesign, UI development, integrating external APIs, and automatically generating APIs for database access and auditing. WaveMaker significantly reduced the time and cost of the modernization project while future-proofing the applications and allowing for scalable operations.

Our client is one of the oldest self-governing body in North America responsible for
regulation of lawyers and paralegals. The organization sets standards for admission into
the legal profession, and works in the public interest by ensuring lawyers meet high
standards of competence and professional conduct and advancing the cause of justice
and the rule of law.

CLIENT SCENARIO
The client used a centralized member management system to manage their data
related to legal professionals they govern. All these data were stored in a built-in DB2 of
IBM AS/400 system and were accessed via green screen applications.
Lack of flexibility to handle changing needs in business processes, rising maintenance
costs, hardware risks and vendor lock-in forced the client to move their proprietary
systems onto standards-based platforms.
WAVEMAKER VALUE ADDS
DB schema redesign - Legacy database was a built-in database with AS/400 which did
not have relationships defined between entities. Client’s member information was
spread across 200+ tables. Since the schema wasn’t designed for efficient operation
at-scale, we had to create a new schema without violating existing dependencies. What
would normally take multiple weeks to generate APIs for the entities took a click of a
button with WaveMaker because it understood dependencies and auto-generated an
efficient API for the newly created modern DB.
User Interface - WaveMaker has preloaded widgets and UI themes optimised for
cross-screen compatibility. We leveraged them and recreated client’s application screens
thus nullifying any project effort spent in creating front-end code.
External integrations - Client’s system leveraged multiple external services (third party
APIs) to achieve extended functionality like reporting. Many of these APIs were SOAP
based. Additionally there were several internal services that had to be integrated.
With WaveMaker we were able to use existing SOAP APIs as it is and even generate a new
API for an existing client service in no time. This made the overall integration effort a lot
more quicker .
API generation - To access DB services with flexibility, WaveMaker instantly generated
DB access API’s with the required documentation. The client also had to ensure
transparent auditing of their data changes, we helped them create specific auditing and
traceability APIs.
WaveMaker was their choice of platform as it automates the bulk of activity required to
carry out a modernization of this scale. It drastically reduces the time and cost of
actioning modernization, future proofs applications and allows for a cost-effective
scalability without compromising on system resilience.
