Abstract: A method of handling a client's request for origin/destination and/or departure/arrival time is provided. Data is gathered from content-provider platforms and transport-service graphs, corresponding to public-transportation networks, are generated with their nodes representing stops in a corresponding public-transportation network and their internal edges representing connections. A connection graph including the transport-service graphs is generated. Origin/destination nodes are selected in the connection graph as well as routes between these nodes. Therein, successive segments for a route, corresponding to transportation connections between nodes of a transport-service graph are joined. Queries asking price, availability, departure/arrival time based on departure/arrival time of the request and estimated travel duration of a selected route's segment are sent to content-provider platforms.

The computing resource creates user interface information of the at least one data record and is configured to allow a second computing device of the plurality of computing devices to display a representation of the selected at least one data record in a user interface of the second computing device. The user interface information has a second data size that is smaller than the first size. The computing resource transmits the user interface information to the second computing device.

Abstract: A distributed computer system for delivering data to client-side application(s) is provided. The system includes a database configured to store immutable data blocks, a data distribution entity configured to split source-data into immutable data blocks and metadata. The data distribution entity is configured to replicate and store the data blocks on different storage nodes(s) of the database.

The system further comprises a data fetching/delivering entity with a fuse-daemon configured to form a quorum read request for data block(s) out of a client-side request for a certain data range. The quorum-read request is a bundle of parallel requests to different storage nodes. The fuse-daemon is configured to fetch the data blocks delivered in the fastest response and to discard the rest. The fuse-daemon generates a virtual file comprising the corresponding range of data from the fetched data blocks.

Abstract: Data is processed iteratively by a database system with a first cache storing key-value data which resulted from previous iterations of processing input data and a second cache storing aggregated data which resulted from previous iterations of processing key-value data stored in the first cache. In a current iteration, the database system receives further input data related to the input data of the previous iterations, transforms the further input data into further key-value data and stores the further key-value data in the first cache in addition to the stored key-value data which resulted from previous iterations. The database system further processes the further key-value data and the aggregated data stored in the second cache to form updated aggregated data, and stores the updated aggregated data in the second cache for usage in further iterations. The database system also provides the updated aggregated data to at least one client.

Abstract: Incremental data processing at a computerized device includes determining a number of data sets from a plurality of data sets, each comprising values in at least two dimensions. The device accesses priority lists for a subset of the data sets. The priority lists specify data values for an ordered number of dimension value sets. Each priority list is sequentially processed to determine the specified data values for combinations of dimension values that apply to device requirements. Processing is aborted when a data value is determined for each combination of the dimension values that apply to the device requirements. A data value is selected among the determined data values. A number of data sets is determined based on the selected data values. A network route from a source device to a target device can be determined in this manner.
