Embodiments of methods and systems consistent with the invention transform business application operations, rules, and schemas into OOP constructs that represent the operation, rule, or schema, emulate its operation in terms of sequence with other operations, and represent its relationship(s) to the data it operates with and upon in the business application. An automated system determines each operation that makes up a schema or rule in the business application by analyzing the database table(s) that hold the schema or rule. The system may transform the business operation into part of an OOP model by declaring or creating an empty OOP language construct to represent the operation, such as a Java™ function or method. The transformation process may be controlled by a set of transformation rules.

Systems and methods for describing imaging tasks across a distributed environment of imaging clients, servers and devices, wherein the tasks include complex imaging operations, and interchanging imaging data and operations. The imaging jobs include diverse imaging tasks that can be constructed in a single program unit. The imaging tasks are constructed using a single imaging job language and common interface across all imaging devices, clients and servers, or managers thereof. A manager communicates with the imaging components through the common interface and translates the operations into the communication methods that are compatible with the devices, clients and servers. Composite imaging jobs are selectively dispatched to diverse imaging components through a single imaging spooler subsystem. Further, distribution may occur across various imaging devices, clients and/or servers, such that a first imaging system performs some subset of steps, deletes the executed steps and makes the appropriate substitutions or interchanges and the portion is performed by a second and/or subsequent imaging system.

A system and method for coordinated manipulation of multiple displayed maps, even when the maps use different internal coordinate systems. According to this embodiment, each map image to be displayed is first georeferenced, to provide a set of conversion functions between each map's internal coordinate system and a geographic coordinate system, which is latitude/longitude in the preferred embodiment. After this is done, any point on each map can be referenced using the geographic coordinate set. Since this is the case, the maps can now be manipulated, edited, and annotated in a synchronized manner, by defining the manipulations in terms of the geographic coordinate system, and using the georeferencing functions to translate the manipulation to each map's internal coordinate system.

Access management techniques have been developed to specify and facilitate mappings between I/O and host domains in ways that provide flexibility in the form, granularity and/or extent of mappings, attributes and access controls coded relative to a particular I/O domain. In some embodiments of the present invention, operation translations coded relative to a particular logical I/O device, domain or sub-window seek to optimize functionality, isolation or some other figure of merit without regard to needs or limitations of another. In this way, operation translations need not be uniform and need not reduce supported operation semantics to correspond to that of a lowest common denominator I/O device. In some embodiments, the form of mappings (e.g., of operation translations) may be specialized on a per-logical-device basis (or even a per-sub-window basis), thereby offering individual logical I/O devices (or sub-windows thereof) immediate, indexed, and/or untranslated operation mapping frameworks appropriate to their individual requirements or needs. In general, flexibilities and efficiencies afforded in some embodiments of the present invention can be desirable, particularly as the diversity of I/O device types and richness of transaction semantics supported in interconnect fabrics increase. Some embodiments may be leveraged in support of sophisticated system partitions or I/O virtualizations.

A term of use policy document defines permissible actions that may be implemented by a user using a computing device. A natural language processing (NLP)-based question and answer (Q&A) system is trained to understand the policy document. The device includes a management application that interacts with the Q&A system to identify a policy violation. When the user performs an action on the device, the application converts that action into an NLP query directed to the Q&A system to determine whether the action constitutes a violation. The query may be accompanied by metadata associated with the user, the device or its state. Upon receipt of the query and any associated metadata, the Q&A system determines if the user action is compliant with the policy and returns a response. Based on the response, the user's computing device may take an enforcement action, e.g., restricting or disabling functionality, or issuing a warning.

The method comprises the following steps of selecting a target repair path from time sequence violation paths, grabbing all basic units and the delay values corresponding to the basic units in the target repair path and sorting, and sequentially selecting the basic units as the target units according to the sequence; judging whether the violation is an establishment time violation or a retention time violation, replacing the targetunits sequentially based on the rules which do not affect other time sequence paths, and obtaining the repair operation meeting requirements; and converting the repair operation into an operation command which can be identified by a layout wiring tool, executing the operation on the layout wiring tool, and ending the repair under the condition of verifying that the time sequence analysis result after the operation meets the time sequence requirement. According to the invention, when the time sequence violation repair is carried out, the re-layout and the re-wiring are not needed, and the timesequence convergence can be realized through the rapid iteration.

Access management techniques have been developed to specify and facilitate mappings between I/O and host domains in ways that are storage-efficient and which can provide flexibility in the form, granularity and/or extent of mappings, attributes and access controls coded relative to a particular I/O domain. Indeed, different identifier and/or operation translation models may be employed on a per logical device (or even a per sub-window) basis. In general, the flexibility and efficiency afforded using some embodiments of the present invention can be desirable, particularly as numbers of I/O domains increase, such as in the case of virtualization system implementations in which a multiplicity of logical I/O devices may be represented using underlying physical resources.

The consistency of a data structure is maintained where changes in the form of atomic operations are requested by more than one user to an object graph containing a plurality of objects. Operational transformations specifying how one atomic operation is transformed against another one are accessed and the object graph is modified with the first and second set of changes by employing the operational transformations on the atomic operations and applying the resulting transformed operations to the object graph. The transformed operations are recorded in a history log. The atomic operations are object operations that create or delete an object of the object graph and/or property operations changing a property of an object. Each operation retains the identifier of the object it acts on and information on each change of the object resulting from the operation. Multi-operation conflicts are resolved by defined conflict resolution events.
