The following describes the data management method of the seismic processing platform based on the data model in more detail:
the data model-based seismic processing platform data management method of the embodiment of the invention mainly comprises three parts of abstract data model tree, data model service and data model event proxy.
(1) Abstract data model tree
The data model tree is the basis of seismic data management, and provides an organization mode, an access mode and an expansion mechanism of a data model for a software platform. The concept of the data model tree is as follows:
the data management interface is a tree data structure example composed of unified data object model CPaiObjects as nodes, each node is an example of a derivative class of CPaiObjects, for example, the root node represents a processing project manager, the first layer node represents a project, the second layer node represents a work area, etc.
The CPaiObject class serves as the base class for all domain object models (in the hydrocarbon domain, typical data object models include project, work area, seismic data, velocity analysis data, logging data, horizon data, etc.). CPaiObject consists of elements such as ID, name, icon, status, and list of children. The ID is used to identify the object at runtime, the name and icon are used to support display, and the state is used to represent the runtime state of the object. CPaiObject also specifies interfaces that some derived classes need to implement, such as GetProperties interfaces get detailed statistics of the Object, and loadFromDB interfaces support loading the content of the derived class instance from a database, etc.
(2) Data model service
The CObjectModelService class serves as a portal for data model access, and at run-time, the whole system has only one CObjectModelService class instance. All interaction modules can get this globally unique instance through the global function GetObjectModelService (). CObjectModelservice contains a data model tree and a global data selection set. The CObjectModelService class is also an object set class for all cpaiobjects, and an instance of the derived class can be created by creating an object interface specifying a type ID. CObjectModelService provides a convenient interface for data model access and project manipulation.
(3) Data model event proxy
CPaiObjectEventAgent is an event proxy class of the data model. CPaiObject may support messaging through a statically public member m_eventAgent. All messages are sent through a plurality of signals of the proxy class, a child is added, inserted and deleted by an object, a corresponding message is sent, and the message parameter comprises a sender and a handle of the child.
The attribute or data of the object is changed, and a signalpropertyChanged message is sent, and the message parameter comprises sender, attribute name and changed value.
