Project Description

Customer was looking for tablet solution to support complex workflows and functionalities, with key requirements like:

• Complex workflows
• Including payment functionality
• All functionality must work on- and offline
• Only a subset of data can be stored on tablet
• Data input is coming from several subsystems, must be merged to be usable
• Data output must be sent back to subsystems
• Subsystems cannot handle data exceptions themselves
• Communication with subsystems is sensitive
• System must be scalable for high load and worldwide rollout

Tasks

• Middle layer for complex communication and information commissioning, based on Java
• Highly secured middle layer, no direct connection from tablets to middle layer
