Embodiments of the present invention manage multiple requests to allocate real world resources in a multi-user environment. A set of resource availability information is stored in a first durable data file for each resource in a plurality of resources provided by a database environment. The database environment is shared between a plurality of users. A decision context is associated with a second durable data file. The decision context is associated with a user interacting with the database environment. The decision context exists for a defined duration of time. A least one resource is determined to have been temporarily allocated to the decision context for the defined duration of time. The second durable data file is updated to indicate that the at least one resource has been temporarily allocated to the decision context. The first durable data file is updated to indicate that the at least one resource is currently unavailable.
