CABEM integrates the property management system (PMS) of a Five Star Boston Hotel to valet and parking software using SHIM; CABEM’s proprietary integration module released in April 2003. SHIM simplifies integration techniques and allows for browser based remote access and metrics management. SHIM (Scriptable Hotel Interface Module) was conceptualized, designed and built by CABEM technologies to allow for transactional integration between a valet parking system and a hotel Property Management System based on existing data input permissions. SHIM uses screen-scraping technology, keyboard simulators, and scripting to replicate iterative keyboard entry. It is deployed using a drop in transactional server. The operating system is derived version of Debian GNU/Linux configured for cost, reliability and efficiency.
