Model Railroad Inventory Manager (MRIM)

This micro-service web component provides a user with a web application to display, create and update information of the inventoried items. It is dependent on two other components:

  • RIDS, which provides services to access the MongoDB collection of rolling stock documents containing a RFID associated to a road name and number
  • MRFM, which provides services to store image files (jpeg) in a file store

The following figure shows the MRIM micro-service in context of the other micro-services needed to provide the application ability to manage inventories.
