Abstract: A framework can provide function execution services. The framework can comprise a controller layer, a wrapper layer, and a function layer. The controller layer can be configured to process function definition requests and function execution requests, and return results. The wrapper layer can be configured to query the function layer to determine function definitions and pass function execution requests and results with the function layer. The function layer can comprise functions and/or features. A function execution request can be performed by determining a step execution sequence, executing the step execution sequence, and returning results of the execution of the step execution sequence. The step execution sequence can comprise setup steps, execute steps, and/or finalize steps.

Abstract: At least one read operation of at least one object of a data container is initiated. The data container includes an anchor object, a first internal data object and a first garbage collection object, the anchor object comprising a pointer to a versioned structure tree. Thereafter, in response to the at least one incompatible write operation, a second internal data object and a second garbage collection object are created for the data container. The second garbage collection object has a reference to the second internal data object. Subsequently, the second internal data object is installed in the anchor object and the first garbage collection object is passed to a garbage collection process so that space used by the first garbage collection object in a database can be reused. Related apparatus, systems, techniques and articles are also described.

Abstract: Data records of a data set can be stored in a plurality of main part fragments retained in on-disk storage. A size of the data set can be compared to an available size of main system memory. All of the plurality of main part fragments can be fully loaded into the main system memory when the available size of the main system memory is larger than the size of the data set. Alternatively, one or more of the of main part fragments can be paged into the main system memory on demand in response to a data access request when the available size of the main system memory is smaller than the size of the data set and the data access request can be satisfied by providing access to a subset of the main part fragments, or access can be provided directly to the on-disk main part fragments when the data access request involves random access for projection in the data set and the available size of the main system memory is smaller than the size of the data set.

Abstract: In one embodiment, a computer-implemented method comprises determining, by a controller, whether a first data store is in an initialization mode. The first data store stores client data. A second data store stores credential data of the first user and credential data of a second user. An application server includes a first secret key store. An in-memory database server includes a second secret key store. The method further comprises, if the first data store is in the initialization mode, receiving, by the controller, from the second user a secret key for encrypting the client data stored in the first data store; and storing, in the first key store, the secret key. The method further comprises, in an operational mode, authenticating the first user based on the credential data of the first user; if the first user is authenticated, processing, in the application server, a user request from the first user.

Abstract: The present invention provides an index structure for managing weighted-sequences in large databases. A weighted-sequence is defined as a two-dimensional structure in which each element in the sequence is associated with a weight. A series of network events, for instance, is a weighted-sequence because each event is associated with a timestamp. Querying a large sequence database by events' occurrence patterns is a first step towards understanding the temporal causal relationships among the events. The index structure proposed herein enables the efficient retrieval from the database of all subsequences (contiguous and non-contiguous) that match a given query sequence both by events and by weights. The index structure also takes into consideration the nonuniform frequency distribution of events in the sequence data.

Abstract: A view object is generated in a target deployment unit in a design time environment of a metadata repository. The view object is modeled on a business object of a source deployment unit. The source deployment unit includes process components of a business application that is physically decoupled from the target deployment unit. A subset of attributes of the business object of the source deployment unit is selected. The subset of attributes includes at least an outbound agent and an inbound agent implemented by a generic messaging framework. The view object is modeled in the target deployment unit with the subset of attributes of the business object. The inbound agent of the view object is configured for receiving a replication message from the outbound agent of the business object, and the replication message includes replication data for configuring the view object only with data from the business object.

Abstract: Data is received that comprises at least one data stream derived from each of a plurality of sensors that each characterize one or more attributes of equipment components. Thereafter, using the received data and a density-based clustering algorithm that produces micro-clusters for each pair of sensors, correlated sensors having component correlations above a pre-defined threshold are identified. It can then be determined that data from two or more correlated sensors triggers at least one alert event. Subsequently, data is provided that characterizes the at least one alert event. Related apparatus, systems, techniques and articles are also described.

Abstract: In one embodiment, a method determines data stored in a plurality of tables in a first database for archiving. The data is combined from the plurality of tables into a set of objects in a readable format where an object in the set of objects includes terms from the plurality of tables associated with the object. The method then stores the set of objects in the text format in a second database where a search query processor is able to search terms in the set of objects in the readable format. Then, the data stored in the plurality of tables in the first database is deleted in response to the archiving.

Abstract: Techniques for retrieving and displaying information from a business system on a mobile computing based on contextual details are disclosed. The contextual details can include caller identification information and contact identifiers associated with the caller identification information stored a contacts record in a mobile computing device. Contextual details may include caller identification information, contact identifiers, user preferences, job functions, time/date, and location. Based on the specific details of a particular context, an associated layout definition can be determined. The layout definition specifies the information and analysis to retrieve from the business system and the manner in which to display the information in a graphical user interface if a mobile computing device.

Abstract: A technique is described to selectively synchronize content on a client database with content from a server database. As the user traverses a hierarchical folder structure of the client database, he may run into content that has been deleted or moved in the server database. If the content is something that the user wishes to store locally, the content can be stored as an orphan. An orphan is content stored on the client that cannot be traversed by the hierarchical folder structure. When the user traverses to a node in the hierarchical folder structure that is missing an object existing on the server, a determination can be made as to whether the orphan object is the missing object. If so, the orphan object can be connected once against to the hierarchical folder structure. This may minimize the content that needs to be re-downloaded from the server.

Abstract: Embodiments assess risk posed by changing a computer system present within a landscape of other computer systems. Agents provide a central assessment engine with data relevant to considerations such as system criticality, correlation between related systems, and dependence between different systems. The criticality parameter reflects an importance of a system and a corresponding change risk impact. System correlation is measured to allow comparison between systems, and a risk of failure of a change to the systems. Dependencies between systems are measured to define a set of systems to be changed in a coordinated manner. Change statistics collected in a database, may allow correlating systems across various customers, improving accuracy of risk prediction. Embodiments may facilitate iterative planning, where a different dependency permits the definition of smaller sets of systems offering lower risk of failure upon change implementation.
