Application Research Of Data Driven Business Model In The Geological Disaster Emergency Management

China is one of countries with the most serious natural disaster damaged,especially geological disasters occur frequently, poses a great threat to people’s livesand property safety, in order to deal with geological disaster emergencies, the Chinesegovernment issued a series of measures, within these measures, the geologicaldisaster emergency command platform as a whole emergency command informationsystem supporting platform has great significance for geological disaster emergencymanagement.At present, coping with geological disasters, emergency command system has aninitial scale in China, and the whole nation, the province, the county, the city, theautonomous region are both in the emergency command platform construction, ourcountry emergency command system has achieved initial scale. However, in thepractical application of the emergency command system, some problems aregradually exposed, mainly reflected in the spatial data resources scatter, much specialdata, little sharing data, lack of spatial information standard, and the integration isdifficult. In addition to the construction of application system, data and business logicis bound very tightly; the construction of the database is intended to serve a system,lead to the application is single.The problems occur in the geological disaster emergency command system is areflection of the current problems facing big data problems, there are two mainaspects of big data problem in the field of geological disaster emergencymanagement:1. Emergency management data organization management and data sharingproblems brought by the big data. Emergency command system has obviouscharacteristics of big data, mainly in: first, the huge amount of data volume, build onlyone provincial emergency command system requires a dozen TB data that needorganization and management, update data has several TB once a year, and the datavolume is still increasing; second, the range of data types, multiple sources ofemergency data, there are seismic data, meteorological data, the disaster data etc.,data type includes both structured data and unstructured data, and mainly focus on unstructured data; third, low value density, high practical value, emergency commandsystem has video monitoring data, monitoring data of sensor etc., these data may beused only one or two seconds; fourth, fast processing speed, in response to publicemergencies, emergency command system must be fast processing of emergencymanagement data, fast response and sensitive to various types of emergencies.2. Emergency command brings big data applications business cured, it isdifficult to expand the system’s business functions, bring the problem that theapplication is single. If the emergency management department or emergencymanagement agencies adjust management or make the innovation about theemergency management, emergency procedures will change with the business, whilethe data is constantly growing. Traditional data and applications designed to bind verytightly, unable to meet the need includes ever-changing data and business processesfor flexible, dynamic and scalable application systems and promoting the businessapplications to move forward through the analysis of large data mining.For the management of geological disaster emergency facing the arrival of theera of big data challenges and opportunities for development issues, the subject"application study of geological disaster emergency management in data-drivenbusiness model", take the big data technology in geological disaster emergencymanagement application as the study object, relying on the development of the "Sichuan Provincial People’s Government Emergency Command Center ConstructionProject-data exchange and sharing system, emergency GIS geographical informationsystem ". Apply the research results about the "space information network servicemodel on client aggregation services" in the geological disaster emergencyinformation management, the research results include data-oriented architecture(DOA, Data Oriented Architecture), a new generation of spatial information accessmodel G/S (G/S, General browser/Service cloud), data-driven business applicationsbuilt model (DDBM, Data-Driven Business Model).The main research contents of this paper are as follows:1. Research on theory and method based on DOA, the multi-source,heterogeneous, dynamic, massive emergency management data classification methodfor geological disaster emergency management applications.DOA、G/S model、Data-Driven Business Model both use data-oriented conceptsto build theory and method of information system for the age of big data, use the dataas the core, the first is to study the essence of data. Diversified data production method,lead to a lot of expression of the same data, each expression based on the way is not only data characteristics is the performance of organization and management of dataapplication, essence of data is that the expression between the characteristics of dataand the relationship between the data. Use the emergency management data comefrom the provincial emergency command system as a sample, departure from thecharacteristics of emergency data, research expression of emergency managementdata in multi-angle, multi-dimensional way, the formation of multi-dimensionallogical classification, based on the needs of geological disaster emergencymanagement for the classification of emergency management applications; enacted innational laws and regulations information classification standards, based onmulti-dimensional data coding systems approach; research geological disasteremergency management metadata sharing and exchange standards.2. Study of data-driven business application model for geological disasteremergency management.Geological disaster emergency command platform as the basis of geologicaldisaster emergency management support platform, whose basic function is to dealwith daily work and emergency management departments to respond to emergencies.Geological disaster emergency command platform is to respond to emergencies, sothe emergency service in addition to respond to emergencies of business process,There are some daily work business process, such as monitoring testing, platformmaintenance and so on. Use emergency management process of the provincialemergency command center as the example, in accordance with the relevant nationalassociation of emergency regulations and policies, research the relationships betweenthe business processes and data, research approach to build reusable business resourceobject based on the metadata management, research construction method of reusablebusiness objects resources based on geological disaster emergency command system.3. Detailed design and implementation of data-driven business model emergencycommand system.Use the construction of the provincial geological disaster emergency commandsystem as an example, in the guidance of the theoretical and methodological aboutDOA, study the design of the overall architecture of geological disasters emergencycommand system based on data-driven business model, in accordance with thethree-dimensional data classification method based on XML Emergency CommandMarkup Language (ECML, Emergency Command Markup Language) design andimplementation; achieve internal systems and external data sharing and exchange viaECML. By hierarchical classification metadata database, research to build mechanisms to define and the data registration centers that register various emergencydata types; through a unified design business object model of geological disasteremergency management to study mechanisms for resource management based on thedata registration center.4. By a application example named provincial geological disasters emergencycommand prototype system to verify the feasibility of geological disasters emergencycommand prototype system based on data-driven business model.Innovation of this paper is as follows:1. Presents a geological disaster emergency management for data-drivenbusiness model.Facing the era of big data, development of geological disaster emergencymanagement business is facing three changes, the transition from a particular field ofemergency management for multiple areas, comprehensive emergency managementin different sectors, transition from respond to emergencies from the starting point ofthe emergency management into the entire incident occurred before and after thewhole process of emergency management, transition from emergency response from afocus on prevention forecast into focus. For this emergency management trends, wepropose a data-driven business application mode. With this model, the businessprocess is a refinement of a business object, the business object with ECML expressedand data registration and registration center, forming resources reusable businessobjects, so that emergency management change from the "business-driven " into"data-driven ", so as to achieve meticulous management and provide comprehensive,multi-level information services for decision-making, management, operation layer.2. Presents a multi-dimensional (three-dimensional) data classification methodface of the geological disaster emergency management.In data-centric philosophy, study the nature law of the emergency data, for thecurrent situation and development needs of geological disaster emergencymanagement work, we propose a multi-dimensional (three-dimensional) emergencydata classification method, which can guide emergency management informationcoding system, can guide the geological disaster emergency command system toestablish standards for data share and exchange, can build guide data registry.3. Proposed emergency management information coding system based onmulti-dimensional (three-dimensional) emergency data classification method.Under industry standards, national standards, international standards consistentpremise, based on geological disaster emergency management for multi-dimensional (three-dimensional) contingency data classification method, the characteristics ofemergency management, proposed a system of emergency management informationcoding system. With this coding system to achieve organizational management andmulti-dimensional representation of the data emergency management; achieveinformation coding and information coding standards formulated by the stateadministration in the field of geological disaster emergency unity; realize the codingof the current emergency management information and coding structure can beextended; achieve rapid and multi-dimensional data retrieval response of theemergency data.In this paper, the main study results are as follows:To rely on emergency management related projects, design and implementationof provincial geological disaster emergency command system prototype based ondata-driven business model.
