The select company was the Hiplatform.com with the hibot. The mainly work was to provide a knowledge base for the provider and setup the work flows calling our system api to fill in calls to our systems with the chat data and perform the attendance. The choice of the provider in Portuguese language for Brazil was he has integrate other tools in the platform like automation for phone calls, social media and mobile. The team assure by proof of concept with the suppliers that whole solution from the choose the suplier company and the development of the service bus to the ERP will be connect smoothly to third parties by web services in REST and JSON, built according to the business needs. The company has a legacy ERP with many optimization and high performance system in language based in C called Opus which interfaces with architectural file system called Openbase. Thus, many code in Opus which need integration with new systems, so the team developed in PHP a connector for PHPUNIT to made the quality assurance and direct integration to Liferay portal, after that developed a JAVA connector to better interface to any system even another ERP more adhering to the laws in health and insurance like TOTVS. The corporation back office systems in JAVA are made to run in JBOSS 5 server. The service bus in REST JSON made in JAVA are design to work with a Wildfly 8 server to provide an easy flat file communication to the Openbase. The corporation Portal in Liferay deliveries to the main systems for our customers are made in PHP 7. There is also a cordova system to provide a IOS and android experience to the customer systems at our insurance and health plans. The development team has adopted TDD with PHPunit through the use of the cases of uses served in the project vision document and all the rules.
