Management Information Systems
We have developed a flexible technology infrastructure that supports our growth strategy. Our information technology infrastructure is comprised of software and hardware designed to integrate store, distribution and vendor services into a seamless network. All stores, corporate and regional offices, and distribution centers are linked via a communications network, which is based on frame relay technology. Our stores in Puerto Rico are linked to the communications network via satellite. Electronic documents transferred between us and our vendors expedite the ordering, receiving and merchandise payment processes.
