Embodiments enable cooperative transmissions from a group of cells (can include the serving cell and one or more neighboring cells) to a user equipment (UE). The cooperative transmissions emulate Hybrid Automatic Repeat Request (HARQ) transmissions to the UE. Specifically, when the UE is experiencing high interference, the UE's serving cell can create a transmit incremental redundancy (IR) group for the UE, which is used to transmit information in a HARQ-like fashion to the UE. Because interference is reduced, the UE can decode the information at a lower coding rate and higher coding gain.

Conformed dimensional objects and synthetic context-based objects are parsed into n-tuples. A virtual mass of each parsed object is calculated, in order to define a shape of the multiple context-based conformed dimensional data gravity wells that are created when data objects that are pulled into each of the context-based conformed dimensional data gravity well frameworks on a context-based conformed dimensional gravity wells membrane.

A database controller controls a database for storing graph data encoded as triples, each triple having a subject, a predicate, and an object, and each stored within a data item among a set of data items ordered according to the triple stored within. Each data item is stored on a storage node from among a plurality of storage nodes distributed in a network. The database controller includes a storage request receiver configured to receive a request to store a triple in the database, and a data item generation module configured to generate two or more data items each having a different version of the triple.

A first data structure stores indications of storage locations that need to be copied for forming a consistency group. A second data structure stores indications of new host writes, subsequent to starting a point in time copy operation to form the consistency group. Locations of the first data structure and the second data structure are exchanged, subsequent to the consistency group being formed successfully.

Approaches for data integration between multiple IT sources using automated data processing based on target metadata are provided. Specifically, an integration component is configured to load a mapped data set into a table with delta processing based on a configuration object containing, e.g., the source data location, target table name, and source to target mapping. The integration component uses the target metadata to validate data, identify changes, generate the necessary database programming language (e.g., structured query language (SQL)), and run the database programming language with data binding to perform the actual data updates. The integration component leverages the data target metadata to automate the processing of source data, thus providing a way to validate the data, and identify delta changes at the field level between the source and target. This significantly reduces the overall development effort, while providing consistency in record handling and error reporting.

Mapping information that specifies attributes of destination entities in terms of attributes of source entities is received. At least some source entities correspond to respective sets of records in one or more data storage systems. The mapping information is processed to generate a procedural specification for computing values corresponding to attributes of destination entities. Collections of nodes are generated, each including a first node representing a first relational expression associated with a specified attribute. At least some collections form a directed acyclic graph that includes links to one or more other nodes representing respective relational expressions associated with at least one attribute of at least one source entity referenced by a relational expression of a node in the graph. At least two of the collections are merged with each other to form a third collection based on comparing relational expressions of nodes being merged.

Many websites publish variants of their web pages based on language and region. However, when a user is directed toward the incorrect web page for the user's language preference, it there is not a simple way for the user to select the appropriate localized or region specific version of the web page. According to an embodiment, a language preference from a user may be received. A first language for a first web page may be identified and the first web page may be received by a computing device of the user. A second language for a second web page may be identified. The second web page may comprise an alternate version of the first web page. The first web page or the second web page may be selected according to the language preference of the user and the selected web page may be presented to the user.

Systems and methods for assigning scores to objects based on evaluating triggering conditions applied to datasets produced by search queries in data aggregation and analysis systems. An example method may comprise: executing, by one or more processing devices, a search query to produce a dataset comprising one or more data items derived from source data; and responsive to determining that at least a portion of the dataset satisfies a triggering condition, modifying a score assigned to an object to which the portion of the dataset pertains.

The present disclosure is directed to systems, methods, and computer-readable storage media for publishing data. A data summary summarizing the data can be generated and published according to several publishing schemes. In some embodiments, non-zero entries are selected and modified and zero entries are sampled according to one or more distribution functions. The sampled and modified values are added to a data summary, or a sample of the sampled and modified values are added to the data summary. The data summary is published, released, used, or otherwise output. In other embodiments, priority values are assigned to each value associated with the data, and a number of entries with the highest values are selected and added to the data summary.

A method of generating a query plan for accessing a database, comprising: receiving (S10) one or more electronic queries from a database client; and determining (S20) whether the received one or more queries form a part of a query pattern comprising a repeating sequence of a plurality of queries by determining whether the received one or more queries match a part of the sequence of queries. If the received one or more queries are determined to form a part of the query pattern, the method further comprises generating (S30) a query plan for executing one or more queries in the sequence that match the received one or more queries, and a query that is subsequent to the matching one or more queries in the sequence.

Techniques are provided for caching external data sources for SQL processing. According to an embodiment, a database system receives a query that requires foreign data from an external data source. In response to receiving the query, the database system determines whether the foreign data currently resides in a cache of the database system. In response to determining that the foreign does not currently reside in the cache, the database system retrieves the foreign data from the external data source, maps the foreign data to a column granule of a table, and stores the column granule in the cache. In another embodiment, the database system receives a second query that requires the foreign data. In response to determining that the foreign data is cached with the stored column granule, the database system retrieves the column granule from the cache.
