A student information system (SIS) is a software application for education establishments to manage student data. Student Information Systems (often abbreviated as SIS systems) provide capabilities for entering student test and other assessment scores, build student schedules, track student attendance, and manage many other student-related data needs in a school.
The SIS is equivalent to an Enterprise Resource Planning or ERP system for a corporate customer. As such, many of the issues with ERP System Selection Methodology, implementation, and operation of an ERP system apply too.
Inventory management System is a computer-based system for tracking inventory levels, orders, sales and deliveries. It can also be used in the manufacturing industry to create a work order, bill of materials and other production-related documents. Companies use inventory management software to avoid product overstock and outages. It is a tool for organizing inventory data that before was generally stored in hard-copy form or in spreadsheets. It is often associated with and is similar to distribution software, as distributors that can compete with less cash tied up in inventories have a distinct advantage over their competitors.
Point of sale (also called POS or checkout, during computerization later becoming electronic point of sale or EPOS) is the place where a retail transaction is completed. It is the point at which a customer makes a payment to the merchant in exchange for goods or services. At the point of sale the retailer would calculate the amount owed by the customer and provide options for the customer to make payment. The merchant will also normally issue a receipt for the transaction.
