Abstract: Systems and methods for managing an airport passenger processing system. The system includes a computing device and a peripheral device at an airport, a peripherals interface in communicative connection with the peripheral device and operable to execute a second client application, and a network outside the airport. The network includes a virtualization server for virtualizing an application for a first client application executed by the computing device and a peripherals manager in communication with the virtualization server. The first client application is configured to establish a first communication channel with the virtualization server for communication with an application virtualized on the virtualization server. The second client application is configured to establish a second communication channel with the peripherals manager.

Abstract: Computer-implemented methods and systems are provided for managing databases. Consistent with disclosed embodiments, a database system can serve configuration requests received from administration systems using an active cluster of at least two geographically separated computing clusters. Serving configuration request can include updating an active configuration database of the active cluster based on the configuration request. The system can also serve search requests received from user devices that specify a search criterion using a closest one of the geographically separated computing clusters by retrieving items satisfying the search criterion from local copies of a cache replicated across the geographically separated computing clusters. Furthermore, the system can serve transaction requests received from the user devices using the active cluster by updating an active local copy of the cache replicated in the active cluster.

Abstract: Systems, methods, and computer program products for associating a unique identifier with an object. The system may include a database with a memory unit, an index unit, and a control pointer unit, at least one identifier management unit, and at least one update unit. A finite set of identifiers is organized in pages, and each page includes a bitmap representing the availability of the identifiers. The pointers to data in the index include a pointer to a last page loaded by an identifier management unit, and a pointer to a last page updated by an update unit.

Abstract: Systems, methods, and computer program products for processing an online transaction to purchase an itinerary of products. In response to processing of the online transaction being halted, an OLTP system may queue a database record defining the itinerary and the forms of payment being used to purchase the products in the itinerary. In response to receiving a request to restart processing of the online transaction, the OLTP system may de-queue the database record, identify a set of products in the itinerary for which processing of the transaction has not been completed, and determine the status of each product in the set. Based on the status of each product, the OLTP system may determine a point at which processing should be restarted for the product, and a sequence in which the products should be processed.

Abstract: Computer-implemented methods and systems are provided for cross-cluster service provision. Consistent with disclosed embodiments, a system for cross-cluster service provision includes a first computing cluster and a second computing cluster. The first cluster includes service-providing nodes, and a first controller that collects status information concerning the service-providing nodes, the status information indicating at least one service-providing node endpoint. The second computing cluster includes service-consuming nodes, a service that receives requests for the service from the service-consuming nodes and distributes the requests among a set of specified endpoints, and a second controller that performs health checks on the specified endpoints, retrieves the status information from the first controller, and updates the set of specified endpoints based on the status information.

Abstract: The disclosed systems and methods include a contextual recommendation engine comprising at least one processor; and at least one non-transitory memory containing instructions. When executed by the at least one processor the instructions cause the contextual recommendation engine to perform operations. The operations include receiving a description of a first service from a service provider. The operations also include receiving content selection rules that map user contexts to services. The operations also include receiving a first script including instructions for providing services. The operations also include associating the first service with the first script. The operations also include receiving, from a first touchpoint, touchpoint data concerning a first user. The operations also include updating a stored context of the first user based on the touchpoint data. The operations also include selecting the first service based on the updated context and the content selection rules.

Abstract: Systems, methods and computer program products for determining a list of products in response to a client request received from a client device during a request/response session. Occurrence frequency and auxiliary product value information for each auxiliary product set in a list of auxiliary product sets are determined from a tree data structure in response to a client request. A list of candidate auxiliary products for each main product is determined using the occurrence frequency and a service value determined for each auxiliary product set in the list of auxiliary product sets.

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.
