US Patent 10049338 Real-time in-memory charge computation

In an embodiment, a transport management application is executing in the application layer. User may place orders by specifying order data in a user interface of the transport management application, and initiate calculate charges to calculate transportation charges for the orders. Based on the initiation, the charge calculation function is invoked in the application layer. Charge calculation function reads the order data specified in the user interface, and invokes charge computation engine in an in-memory database. Orders are split and grouped based on number of dimensions in a rate table. Charge computation engine looks up master data and computes transportation charges for the grouped orders in parallel. After the charge computation engine determines the transportation charges for the orders, sum of the transportation charges is returned to the application layer.
