Abstract: A method may include receiving a query for data to be provided by a database server, wherein the query includes an indication of a maximum lag. The method may further include determining whether a hint is available to apply to the query, wherein the hint affects an execution of the query. When no hint is available, a baseline database server may be selected to be the database server. When the hint is available, a replication server or a cache server may be selected to be the database server based on the hint and the maximum lag. The query may be processed at the selected database server.

Abstract: Systems, methods, and computer program products are provided for planning production processes. In one implementation, a method is provided that includes the steps of planning a sequence of processes running on a resource, where the planning takes into account setup times for the resource for a process depending at least on predecessor process information, storing the sequence of processes, and defining time intervals for the resource within which setup times for processes are held constant independently of the predecessor process information.

Abstract: A method for providing a planning framework for use in managing a material flow of products in a supply chain. According to the method, subsequent instances of said material flow are associated with linked documents in a document flow. In a prior document, first relations are established identifying one or more dependent documents, for producing one or more products in a next instance of said material flow. Said prior document is converted into said next document in a forward way. According to the invention, the method comprises establishing in said next document the first relations identifying said one or more dependent documents, so as to convert said next document into said prior document in a reverse way. In this way, fixed relations can be preserved between product requirements and products while changing the material flow.
