Abstract: Messages are processed in a distributed messaging system by a message processing engine. Message targets operates according to a first standard or a second legacy standard. In response to receiving a database commit indication, a message envelope is generated for each message target to be notified operating according to the first standard and at least one messages within each message envelope. Message envelope dependencies between generated message envelopes for a same message target are computed. Message dependencies between the messages within each message envelope are computed based at least on the standard of the messages of the respective message envelope and functions of the messages. The messages are sent to the respective message target in a sequence based on the message envelope dependencies and the message dependencies.

Abstract: Systems, methods, and computer program products for aggregating data from related database records. A booking folder database stores a plurality of booking folder records. Each booking folder record links reservation records and other data relating to a particular trip or group of trips by storing identifiers identifying the reservation records to be linked. To view or modify a trip, a client application may search the database for a booking folder record matching a search term. Based on the identifiers in the matching booking folder record, the client application may retrieve the linked reservation records, and aggregate the reservation records into a single booking folder view of the entire trip. To modify the itinerary of the trip, the client application may add or remove links from the booking folder record, or modify the linked reservation records.
