Design And Implementation Of System For Heterogeneous Data's Migration In Shenli Oilfield

In database management and database development, data migration is one of the most commonly used functions. Due to the complexity of the oil business brought about by the complexity of the data, the present large number of structured data and unstructured graphics, documents, large data and its relevance to each other so that data migration has gradually become a work of exploration data acquisition, management core and difficult. In this paper, data migration system from the background and objectives of development, data migration, introduced the organizational structure of the system and data-processing processes, to explore how a distributed database in accordance with the integration, the establishment of an integrated data center for ideas and the development of a set of oil to meet current automated enterprise data migration tool for exploration.In this paper, the design of software architecture in the study, the innovative use of the MVC framework to model the separation of view and controller so that a model can have multiple display view. Users to view part of the user interface to determine the rules of data conversion tasks. Part of the model of persistent charge of container management, the memory storage for the object with the XML conversion. Control to achieve the main part of the business operation and business rules, including the user's data warehousing, write xml, file migration, a series of operations such as automatic updates. Overall technical framework for the establishment of such a definition through a model change - the spread of the mechanism, allowing the system to a high degree of scalability.In technology, the present paper from the database related to the concept and characteristics of the start, when the rules of data conversion, data migration method, multi-database data type mapping, large-scale field data processing, and other infrastructure on the basis of technology, the use of task migration definition and acquisition, dynamic loading function, a variety of fields dealing with large databases, middleware channels, quality control, scheduling services, key technologies, the realization of the various types of heterogeneous data-one mapping to ensure that all types of data acquisition, processing, mapping and transfer technology to achieve integration.The study finally provides users with a visualization and automation tools, allowing users to fully and effectively manage the relocation of the operation, the system built the fields of petrOLEum exploration and development of data exchange and data integration applications, unified framework. Not only reduce the data acquisition and management of labor costs, but also for a comprehensive analysis of exploration data provided strong support, with the current deepening of the integration of data applications, the system will increasingly become information-based oil field in the work of an important link. Project examples show that the system has good practical value.
