A robust toolkit that can be configured and assembled in an object-oriented manner to develop a custom case management software application. The toolkit provides a set of software components that serve as a framework for integration with off-the-shelf components. The software components are organized in a vertical layered architecture, with each layer depending upon the layers below it. The toolkit includes a top enterprise application layer, a middle case management application layer, and a bottom customized application layer. The toolkit allows developer to focus on meeting the specific case management needs of a target business / organization, instead of developing case management business logic and application logic from the ground up.

File formats systems and methods are disclosed that provide a framework that integrates concepts, such as objects based audio-visual representation, meta-data and object oriented programming, to achieve a flexible and generic representation of the audiovisual information and the associated methods to operate on the audiovisual information. A system and method are disclosed for storing data processed from presentation data. The data is stored according to a method comprising coding input presentation data by identifying objects from within the presentation data, coding each object individually and organizing the coded data into access layer data units. The access layer data units are stored throughout a plurality of segments, each segment comprising a segment table in a header portion thereof and those access layer data units that are members of the respective segment, there being one entry in the segment table for each access layer data unit therein. A plurality of extended segments are also stored, each of the extended segments further comprising one or more of the access layer data units that include protocol specific data, the extended segments each represented by a extended segment header. The data of an accessible object is also stored, including an accessible object header and identifiers of the plurality of extended segments, each of the extended segments being a member of the same object.

An integrated architecture (a) provides for optimization, indexing, and backtracking search in a business logic layer, (b) provides for general-purpose programming idioms including recursive function definitions, iteration, and dynamic dispatch in data layer queries and updates, and (c) eliminates processing overhead and maintenance issues caused by transforming between relational, object-oriented, and semi-structured data paradigms.

The invention discloses a processing method and system for updating and changing the interface theme of a WinCE product. The method comprises the following steps: when the WinCE application program is developed, separating an interface presentation layer from a business logic layer by adopting a design mode of separating interface layout from program codes, adopting segmented modular programming in the interface presentation layer, and adopting independent XML extensible markup language to describe the elements of the interface theme for each module; when a user interface is required to be amended, writing and amending xml (extensible markup language) interface configuration files relevant to the modules, controlling and realizing the loading engine of the interface element according to the amended contents, mapping the label elements in the amended xml (extensible markup language) interface configuration files into internal storage objects, and automatically generating the user interface layout of the corresponding amended modules. The interface layout and the program codes are separated, so that the problem that the application program interface cannot be freely customized by a client is solved, and simultaneously, the development efficiency of the application program is improved.

The invention discloses a CIM model stream data conversion method and apparatus based on a JAVA platform. Firstly, the CIM model stream data conversion method and apparatus of invention are developed based on the JAVA platform, and adopt an object-oriented CIM model modeling thought. Compared with apparatuses and methods developed through adoption of the non-object-oriented language programs, the development of the method and apparatus of the invention have simple idea and meet the requirements. Secondly, in the process of the conversion, the data structure of the bottom layer of HashMap is used to reduce the search amount when the data is matched, and the speed of CIM model conversion is accelerated. Finally, in dealing with non-switch-type equipment, assessment of whether the equipment is in on-line operation is conducted according to states of switches to ensure the correctness of the conversion results.

The present disclosure relates to a construction method of an object-oriented kernel layer database, which is characterized in that, when the database is running, all data is stored in the memory allocated by the kernel layer, the database is object-oriented, and is uniformly described by an architecture definition, The access unit of the database is the object and the object attribute. The database includes: the interface layer, which is used to receive and process the access request of the object and the structured query request; the logic layer, which is used to realize the access of the object; among them, the operation of the object It is based on object identification, which can be calculated and converted into an object pointer in a programming language; the physical layer is used to realize data access of objects and object attributes; the physical layer is also used to store global index tables, which are used to establish specific The path index of type objects; the physical layer is also used to realize the persistent storage of object data and object attribute data. As a result, it meets the storage and query requirements for complex objects in the kernel scenario and improves access efficiency.

The invention relates to the technical field of process control systems, and discloses a self-adaptive construction method and operation method of a control system for decoupling process flows, and abstracts the commonality of process flow control logic as a logic network description. Describe the input of the control logic as a condition: describe the intermediate operation layer of the control logic as a condition set; describe the output of the control logic as an event: the event is used to control the action of the controlled device, and the occurrence of an event is determined by a dependent condition set Drive, match the corresponding condition set for each event as a dependent condition set; according to the logical network description, use the object-oriented programming method to create objects according to the logical network description and establish network connections between objects, so as to build a control system. The invention solves the technical problem that the control program needs to be programmed according to the steps of different technological processes, and the conditions, condition sets and events are highly combinable, and the logic forms that can be realized are rich, without relying on professional programming skills.

The invention discloses an intelligent object-oriented programmable automatic control method. The object-oriented design concept is adopted. When compiling the action flow of a device, only the controlled device and the controlled action need to be set without Consider the peripheral interface and register configuration at the bottom of the hardware; in this method, the programming part of the control step is used in the application programming method to read the controlled object and action authority from the underlying terminal, and compile the action command of the controlled object according to the action authority, which is applicable to any Equipment automation control equipment.
