In response to the user command, the at least one communication service message is transmitted via a communication network to the second communication device.

Abstract: A table selector may receive a selection of a replicated table storing data replicated from an original table of a first system, the replicated table being stored using a second system and currently executing a process of receiving the replicated data. A suspension manager may suspend the process of receiving the replicated data, and a table attribute manager may change a replicated table attribute of the replicated table, while the process of receiving the replicated data is suspended. The suspension manager may then resume the process of receiving the replicated data.

Abstract: Systems and methods for determining alternative visual analytics are described. Visual analytics result from the application of visual analytic patterns that include instructions for generating visualizations of analytical data. Analytical data is the result of the execution of analytical operations specified in a report definition on an underlying business object. By analyzing the metadata associated with the report definition or visual analytic pattern, alternative visual analytic patterns may be determined that better represent the character of the analytical data. The metadata may include a mapping that associates alternative visual analytic pattern s with a business object, a report definition, or another visual analytic pattern. Accordingly, the determination of the alternative visual analytic patterns may be based on the mappings. The alternative visual analytic pattern s may then be applied to the analytic data to generate one or more alternative visual analytics that may be selected by a user.

The method may also include attaching the software appliance to an operating system of the virtual server of the cloud computer system.

Abstract: A method of determining potentially fraudulent records in a database comprises defining a detection strategy. The detection strategy is targeted to detect existing records from the database and comprises multiple inputs. The detection strategy is executed on existing records and results are displayed for review by a user. The detection strategy is then dynamically calibrated as desired based on input received from the user, and any modified results are displayed. A calibrated detection strategy is set, and then it is executed on new records to detect potentially fraudulent records warranting investigation. A computer system having a processor and memory storing instructions for performing such methods is also described. A computer readable storage medium having computer-executable instructions for performing such methods is also described.

Abstract: Example systems and methods of assigning shipping orders to delivery vehicles are presented. In one example, a delivery region may be segmented into delivery blocks. A shipping order density may be determined for each of the delivery blocks. Adjacent delivery blocks having corresponding shipping order densities may be merged to yield delivery areas. A cost of using each type of available delivery vehicle to transport a delivery job may be determined relative to a cargo capacity of the vehicle type, a delivery distance, and a shipping order density. Each of the delivery areas may be partitioned into delivery jobs based on the cost of using each of the vehicle types. Each of the delivery jobs may be assigned to one of the available delivery vehicles based on minimizing a total cost of using the vehicles to transport the delivery jobs.

Abstract: In an example embodiment, roles within a job based security model are refactored to roles within a task oriented security model. The task oriented security model comprises task roles, which allow access to functionality and data, and enabler roles, which provide limits on the scope of the task roles. Data such as user assignment data, role to functionality mapping, functionality authorization objects, user identity and organizational data may be combined and normalized to create a mapping of users to functionality and organizational data. A refactoring engine may then examine the map to identify new candidate roles using contiguous regions of the map. Tuning parameters and constraints allow tuning of the candidate roles, and statistical metrics allow evaluation of the candidate roles. Candidate roles may be tested and applied in the new system.

Abstract: A database language (e.g. SQL) is extended to define a transient field whose value is derived from data stored in a database. The value of the transient field is calculated by the database engine for consumption as needed by the application layer, for example as part of a particular data model. The value of the transient field may not be materialized as a persistent field in the underlying database table, or may be selectively materialized based upon a heuristic or hint. Certain embodiments may implement the transient field as a basic elaboration on standard SQL utilizing an identifier. Some embodiments may implement the transient field as an entity where SQL has been extended to accommodate concepts of a higher-level Entity Relationship Model (ERM). The use of constants and/or floating values (e.g. a current time) in connection with transient fields, is also disclosed.

Abstract: Techniques are described for expressing a constraint in a host language. A constraint can be defined in the host language as an event handler. The event handler can be registered to a built-in event associated with an object of the database that the constraint is intended to validate. When the object triggers the built-in event, the event handler is called to execute the constraint. Exemplary built-in events include onSave (trigger the event when the object is saved), onValidate (trigger the event when an explicit call to validate the object is detected), onInsert (trigger the event when the object is inserted), onUpdate (trigger the event when the object is updated), and onCheckBeforeSave (trigger the event when the object is checked prior to saving).

Abstract: A cross system analytics system includes sets of in memory database tables stored on random access memory of the system. Each set of tables corresponds to data from a different source system to provide separation of data from each source system. A separate in memory database schema for each set of tables corresponds to each source system. A replication system is coupled to provide replication of data from the source systems into the sets of in memory database tables. An analytics engine executes cross system views of data in the sets of tables to provide a cross system central and consistent view for reporting and analyzing data for an organization having multiple systems with different database schemas.
