An Ontological Approach to Oracle BPMJean Prater, Ralf Mueller, Bill BeauregardOracle Corporation, 500 Oracle Parkway, Redwood City, CA 94065, USA **********************,***********************,*****************************The Oracle Business Process Management (Oracle BPM) Suite is composed oftools for Business Analysts and Developers for the modeling of BusinessProcesses in BPMN 2.0 (OMG1 standard), Business Rules, Human Workflow,Complex Events, and many other tools. BPM operates using the commontenants of an underlying Service Oriented Architecture (SOA) runtimeinfrastructure based on the Service Component Architecture (SCA). OracleDatabase Semantic Technologies provides native storage, querying andinferencing that are compliant with W3C standards for semantic (RDF/OWL)data and ontologies, with scalability and security for enterprise-scale semanticapplications.Semantically-enabling all artifacts of BPM from the high-level design of aBusiness Process Diagram to the deployment and runtime model of a BPMapplication promotes continuous process refinement, enables comprehensiveimpact analysis and prevents unnecessary proliferation of processes andservices. This paper presents the Oracle BPM ontology based upon BPMN 2.0,Service Component Architecture (SCA) and the Web Ontology Language(OWL 2). The implementation of this ontology provides a wide range of usecases in the areas of Process Analysis, Governance, Business Intelligence andSystems Management. It also has the potential to bring together stakeholdersacross an Enterprise, for a true Agile End-to-End Enterprise Architecture.Example use cases are presented as well as an outlook of the evolution of theontology to cover the organizational and social aspects of Business ProcessManagement.1.IntroductionIn the 1968 film, 2001: A Space Odyssey, the movie’s antagonist, HAL, is a computer that is capable not only of speech, speech recognition, and natural language processing, but also lip reading, apparent art appreciation, interpreting and reproducing emotional behavior, reasoning, and playing chess, all while maintaining the systems on an interplanetary mission. While the solution we present in this paper does not possess all of the capabilities of HAL, the potential benefits of combining semantic technology with Oracle BPM provides the ability to define contextual relationships between business processes and provides the tools to use that context so that ‘software agents’ (programs working on behalf of people) can find the right1 Object Management Group, see 2 Jean Prater, Ralf Mueller, Bill Beauregardinformation or processes and make decisions based on the established contextual relationships.Organizations can more efficiently and effectively optimize their information technology resources through a service-oriented approach leveraging common business processes and semantics throughout their enterprise. The challenge, however, with applications built on Business Process Management (BPM) and Service Oriented Architecture (SOA) technology is that many are comprised of numerous artifacts spanning a wide range of representation formats. BPMN 2.0, the Service Component Architecture Assembly Model, Web Service definitions (in the form of WSDL), XSLT transformations, for example are all based on well defined but varying type models. To answer even simple queries on the entire BPM model, a user is left with a multitude of API’s and technologies, making the exercise difficult and highly complicated. Oracle has developed an ontology in OWL that encompasses all the artifacts of a BPM application and is stored in Oracle Database Semantic Technologies that provides a holistic view of the entire model and a unified and standardized way to query that model using SPARQL.Oracle is actively involved in the standards process and is leading industry efforts to use ontologies for metadata analysis. Oracle is also investigating the integration of organizational and social aspects of BPM using FOAF2. BPMN 2.0 task performers can be associated with a FOAF Person, Group or Organization and then used in Social Web activities to enable Business Users to collaborate on BPM models.1.1 BenefitsThe benefits of adding semantic technology to the database and to business process management in the middleware, driven by an underlying ontology are three fold:1.It promotes continuous process refinement. A less comprehensive processmodel can evolve into a complete executable process in the same model.2.It makes it easy to analyze the impact of adding, modifying or deletingprocesses and process building blocks on existing processes and webservices.3.It helps prevent unnecessary proliferation of processes and services. Combining semantic technology and business process management allows business users across organizational boundaries to find, share, and combine information and processes more easily by adding contextual relationships.1.2 Customer Use CaseThe US Department of Defense (DoD) is leading the way in the Federal Government for Architecture-driven Business Operations Transformation. A vital tenet for success is ensuring that business process models are based on a standardized representation, thus enabling the analysis and comparison of end to end business processes. This will lead to the reuse of the most efficient and effective process patterns (style guide), comprised of elements (primitives), throughout the DoD Business Mission Area. A key principle in DoD Business Transformation is its focus on data ontology. The 2 The Friend of a Friend (FOAF) project, see An Ontological Approach to Oracle BPM 3 Business Transformation Agency (BTA), under the purview of the Deputy Chief Management Officer (DCMO), has been at the forefront of efforts to develop a common vocabulary and processes in support of business enterprise interoperability through data standardization. The use of primitives and reuse of process patterns will reduce waste in overhead costs, process duplication and building and maintaining enterprise architectures. By aligning the Department of Defense Architecture Framework3 2.0 (DoDAF 2.0) with Business Process Modeling Notation 2.0 (BPMN 2.0) and partnering with industry, the BTA is accelerating the adoption of these standards to improve government business process efficiency.2.The Oracle BPM OntologyThe Oracle BPM ontology encompasses and expands the BPMN 2.0 and SCA ontologies. The Oracle BPM ontology is stored in Oracle Database Semantic Technologies and creates a composite model by establishing relationships between the OWL classes of the BPMN 2.0 ontology and the OWL classes of the SCA runtime ontology. For example, the BPMN 2.0 Process, User Task and Business Rule Task are mapped to components in the composite model. Send, Receive and Service Tasks, as well as Message Events are mapped to appropriate SCA Services and References and appropriate connections are created between the composite model artifacts. Figure 1 illustrates the anatomy of the Business Rule Task “Determine Approval Flow” that is a part of a Sales Quote demo delivered with BPM Suite.Figure 1: Anatomy of a BPMN 2.0 Business Rule Task4The diagram shows that the Business Rule Task “Determine Approval Flow” is of BPMN 2.0 type Business Rule Task and implemented by a SCA Decision Component that is connected to a BPMN Component “RequestQuote”. Also of significance is that the Decision Component exposes a Service that refers to a specific XML-Schema, which is also referred to by Data Objects in the BPMN 2.0 process RequestQuote.bpmn.3See /products/BEA_6.2/BEA/products/2009-04-27 Primitives Guidelines for Business Process Models (DoDAF OV-6c).pdf4 Visualized using TopBraid Composer TM4 Jean Prater, Ralf Mueller, Bill Beauregard3.An Ontology for BPMN 2.0With the release of the OMG BPMN 2.0 standard, a format based on XMI and XML-Schema was introduced for the Diagram Interchange (DI) and the Semantic Model. Based on the BPMN 2.0 Semantic Model, Oracle created an ontology that is comprised of the following5:•OWL classes and properties for all BPMN 2.0 Elements that are relevant for the Business Process Model.6The OWL classes, whenever possible,follow the conventions in the BPMN 2.0 UML meta model. OWL propertiesand restrictions are included by adding all of the data and object propertiesaccording to the attributes and class associations in the BPMN 2.0 model.7•OWL classes and properties for instantiations of a BPMN 2.0 process model. These OWL classes cover the runtime aspects of a BPMN 2.0process when executed by a process engine. The process engine createsBPMN 2.0 flow element instances when the process is executed. Activitylogging information is captured, including timestamps for a flow elementinstance’s activation and completion, as well as the performer of the task. The implicit (unstated) relationships in the Oracle BPM ontology can be automatically discovered using the native inferencing engine included with Oracle Database Semantic Technologies. The explicit and implicit relationships in the ontology can be queried using Oracle Database Semantic Technologies support for SPARQL (patterns matching queries) and/or mixed SPARQL in SQL queries. [6] Example SPARQL queries are shown below:Select all User Tasks in all Lanesselect ?usertask ?lanewhere {usertask rdf:type bpmn:UserTask .usertask bpmn:inLane lane}Select all flow elements with their sequence flow in lane p1:MyLane (a concrete instance of RDF type bpmn:Lane)select ?source ?targetwhere {flow bpmn:sourceFlowElement source .flow bpmn:targetFlowElement target .5 All of the classes of the BPMN 2.0 meta model that exists for technical reasons only (model m:n relationship or special containments) are not represented in the ontology6 The work in [2] describes an ontology based on BPMN 1.x for which no standardized meta model exists7 Oracle formulated SPARQL queries for envisioned use cases and added additional properties and restrictions to the ontology to support those use casesAn Ontological Approach to Oracle BPM 5 target bpmn:inLane p1:MyLane}Select all activities in process p1:MyProcess that satisfy SLA p1:MySLA select ?activity ?activityInstancewhere {activity bpmn:inProcess p1:MyProcess .activityInstance obpm:instanceOf activity .activityInstance obpm:meetSLA p1:MySLA}A unique capability of BPMN 2.0, as compared to BPEL, for instance, is its ability to promote continuous process refinement. A less comprehensive process model, perhaps created by a business analyst can evolve into a complete executable process that can be implemented by IT in the same model. The work sited in Validating Process Refinement with Ontologies[4] suggests an ontological approach for the validation of such process refinements.4.An Ontology for the SCA composite modelThe SCA composite model ontology represents the SCA assembly model and is comprised of OWL classes for Composite, Component, Service, Reference and Wire, which form the major building blocks of the assembly model. Oracle BPM ontology has OWL classes for concrete services specified by WSDL and data structures specified by XML-Schema. The transformation of the SCA assembly model to the SCA ontology includes creating finer grained WSDL and XML-Schema artifacts to capture the dependencies and relationships between concrete WSDL operations and messages to elements of some XML-Schema and their imported schemata.The SCA ontology was primarily created for the purpose of Governance and to act as a bridge between the Oracle BPM ontology and an ontology that would represent a concrete runtime infrastructure. This enables the important ability to perform impact analysis to determine, for instance, which BPMN 2.0 data objects and/or data associations are impacted by the modification of an XML-Schema element or which Web Service depends on this element. This feature helps prevent the proliferation of new types and services, and allows IT to ascertain the impact of an XML-Schema modification.5.The TechnologiesAs part of the customer use case, as referenced in section 1.2 above, we implemented a system that takes a BPM Project comprised of BPMN 2.0 process definitions, SCA assembly model, WSDL service definitions, XML-Schema and other metadata, and created appropriate Semantic data (RDF triples) for the Oracle BPM ontology. The6 Jean Prater, Ralf Mueller, Bill Beauregardtriples were then loaded into Oracle Database Semantic Technologies [3] and a SPARQL endpoint was used to except and process queries.6.ConclusionOracle BPM ontology encompasses and expands the generic ontologies for BPMN 2.0 and the SOA composite model to cover all artifacts of a BPM application from a potentially underspecified8process model in BPMN 2.0 down to the XML-Schema element and type level at runtime for process analysis, governance and Business Intelligence. The combination of RDF/OWL data storage, inferencing and SPARQL querying, as supported by Oracle Database Semantic Technologies, provides the ability to discover implicit relationships in data and find implicit and explicit relationships with pattern matching queries that go beyond classical approaches of XML-Schema, XQuery and SQL.7.AcknowledgementsWe’d like to thank Sudeer Bhoja, Linus Chow, Xavier Lopez, Bhagat Nainani and Zhe Wu for their contributions to the paper and valuable comments.8.References[1] Business Process Model and Notation (BPMN) Version 2.0,/spec/BPMN/2.0/[2] Ghidini Ch., Rospocher M., Serafini L.: BPMN Ontology,https://dkm.fbk.eu/index.php/BPMN_Ontology[3] Oracle Database Semantic Technologies,/technetwork/database/options/semantic-tech/[4] Ren Y., Groener G., Lemcke J., Tirdad R., Friesen A., Yuting Z., Pan J., Staab S.:Validating Process Refinement with Ontologies[5] Service Component Architecture (SCA), [6] Kolovski V., Wu Z., Eadon G.: Optimizing Enterprise-Scale OWL 2 RL Reasoning in aRelational Database System, ISWC 2010, page 436-452[7] “Use of End-toEnd (E2E) Business Models and Ontology in DoD Business Architectures”;Memorandum from Deputy Chief Management Office; April 4, 2011, Elizabeth A.McGrath, Deputy DCMO.[8] “Primitives and Style: A Common Vocabulary for BPM across the Enterprise”; DennisWisnosky, Chief Architect & CTO ODCMO and Linus Chow Oracle; BPM Excellence in Practice 2010; Published by Future Strategies, 20108A BPMN 2.0 model element is considered underspecified, if its valid but not all attribute values relevant for execution are specified.。

BPM以及与OA、EAI的区别
今年来,随着计算机技术的发展和互联网时代的到来,我们已经进入了信息时代,也称数字化时代,在这数字化的时代里,企业的经营管理都受到了极大的挑战。
从上个世纪90年代起至今,企业的信息化工作开展的如火如荼,相继建立了很多业务系统,同时也给企业带来了巨大的效益。
但是,新的问题出现了,业务已经对这些复杂的系统提出更新的需求,即需要实现系统之间的整合。
EAI(Enterprise Application Integration)技术风靡一时,成为各界人士追捧的对象。
热闹过后,许多人已经清晰的认识到,EAI仅仅是为解决“数据孤岛”而生,并不能解决业务流程的整合。
另外,虽然很多业务系统也支持工作流技术,但是由于工作流与业务逻辑紧密结合,所以EAI实施的效果大打折扣。
实践证明,优化、高效、低成本的业务流程将为企业提供了与竞争对手拉开距离的法宝,高效的业务流程不仅提高企业的运行高效率,而且降低企业的成本,使企业达到高度自动化。
所以业务流程才是企业的核心问题。
为了使业务系统适应企业的运行机制,需要对众多业务系统进行更深度的整合,包括数据整合、流程整合等,所以,BPM(Business Process Management)随之而产生。
1、BPM是什么
Gartner对BPM的描述摘要:
“Rapid change is impractical while processes are embedded in conventional applications。
The Development of BPM Technologies is enabling business managers to abstract process flows and rules from the underlying applications and infrastructure,and to change them directly。
”
其大意是:嵌入到常规的程序中的流程需要迅速改变是不切实际的。
需要具备让管理人员也可以设计业务流程,需要把流程的逻辑从底层的代码中抽取出来,并且能够直接改变他们。
在理解BPM之前,先谈谈业务流程(Business Process)。
业务流程是企业、政府以及其它各种组织,为了达到其他业务目标,而执行的一系列活动,这些活动必须由两个或者两个以上的人或IT系统执行,串行或者并行,活动的执行需要满足一定的规则和条件。
基于上述理解,BPM应该是一种企业中业务流程管理的办法,而支持其管理的软件叫BPMS(Business Process Management Suite)。
所以BPM应该是企业管理中的方法,而BPMS 是建立、执行、评价和管理企业业务流程的一组软件系统体系,也就是我们常说的软件平台。
概括起来说,BPM应该能体现以下特征:
(1)业务流程建模:业务人员完全以业务的视角,用流程图描述业务流程,也就是流程设计工具。
(2)业务流程自动化:根据定义好的流程,在BPM系统中自动执行,完全废弃传统的纸张,流程的传递不需要人工干预,也就是智能化BPM流程引擎。
(3)系统集成:BPM不仅仅是由人来参与,部分活动也可以由IT 来参与,例如在请假流程中需要在HR系统中判断请假人有年休假期。
这就要求BPM提供执行自动作业功能,如调用WebService、执行某类的方法。
(4)业务流程管理:能够可视化的监控流程的执行情况,对流程执行过程中出现的意外进行处理,也就是提供实时流程监控。
(5)业务流程优化:对流程执行的情况(包括:效率、成本、瓶颈、负载)进行统计、分析。
根据统计分析结果,对流程进行改造,以优化流程的执行,也就是提供流程模拟与分析工具。
业务流程建模是基础,业务流程自动化和系统集成是实现手段,业务流程管理是过程,业务流程优化是目标。
BPM是一个方法论和软件系统的集合,作为方法论,有其自身的规划、实施、管理办法。
在该办法的指导下,由软件系统来实现业务流程的有效管理。
从这个角度来讲,BMP是一个持续性的过程,而这个过程的各个环节将构成一个闭合的循环体,这恰恰迎合了企业成长的过程。
所以BPMS必将给企业的信息化建设、提高企业的市场的竞争力起着非常重要的作用。
2、BPM与Workflow、EAI
首先,我们先看看BPM与Workflow。
谈到Workflow,我们自然会想到OA系统。
八十年代初期,随着大量PC机的生产以及普及化,有一组麻省理工的研发人员首先提出了办公自动化的概念,并在1981年发表了一篇文章:“Etude:An Integrated Document Processing System”。
文章中提到开发一套集成的工具,包括办公工作台以及针对个人交互的软件系统,为办公室员工提高办公的效率。
这套软件系统就是工作流与OA的前身。
国内的OA系统是以文档作为流转的元素,把符合中国国情的国家机关以及国营企业下放正式的红头文,通过支持复杂的工作流程,复杂的人员组织,不同组织机构,不同岗位,进行比如动态会签作业,实现电子表单与人的互动处理工作。
很多人误以为OA或者工作流就是BPM。
其实工作流是
接下来,我们看BMP与EAI
目前,企业出现了很多分散式的应用与系统。
这些系统包括ERP、CRM等业务系统。
但是系统却成了企业的“信息孤岛”,系统与系统之间无法交换信息。
随之,EAI(Enterprise Application Integration)等产品的出现。
很多用户因为BPM提供的整合功能与EAI相似,误以为BPM就是EAI。
但是,EAI和BPM是有很多区别的,EAI从表面上看,解决了信息孤岛问题,实际上,只是解决了数据传输问题,企业中普遍存在的“流程孤岛”的问题,仍然没有被解决。
随着时间与业务需要,EAI与BPM开始汇集了一些新的技术,尤其是Web Services,SOA(Service Oriented Architecture)的出现加速了整个过程。
最终,BPM不是EAI,但是却是EAI的未来发展方向。
主要区别如下:
3、BPM能带来什么
1)提高客户服务的满意度
BPM系统为客户提供单一入口,客户只要通过该单一入口提出请求即可,流程自动把任务分配到相关业务负责人。
由于BPM系统执行效率远远高于人工流程,全面实施BPM系统将会给客户提供更快速的服务响应。
另外,客户是流程环节中的一部分,并通过BPM参与到
业务流程中来,所以,可以随时能够获得流程的进度,使客户对其需求的出来情况有直观的了解,消除了客户的“需求石沉大海”的现象。
2)提高自身的市场竞争力
(1)最优的业务流程运作效率
通过BPM系统允许大规模的并行处理,这大大提高了流程执行的速度。
BPM的任务分配机制,提供了负载平衡、任务队列、后备人选等特性,将任务分配给当前执行该任务最有效的人;BPM的任务提醒机制,使任务执行者能够立即获知其被分配的活动;BPM的监控、统计、分析工具能够最大限度促进流程执行,并使其不断优化。
(2)平衡效率、成本和质量,提高成熟的服务和生产能力
BPM系统能通过组织机构、岗位设置详细定义流程,明确岗位职责和业务规则,减少工作失误。
BPM的监控工具,能够分拣出执行中出现问题的流程,供相关人员进行干预;BPM
的建模工具、仿真预演工具和统计分析工具,能够帮助流程定义者设计出最合适该组织的流程。
(3)提高适应变化的能力
市场、客户、竞争者都在变化,要求一个组织必须快速变化,适应新的形势。
有时之所以出现组织适应变化的能力差现象,是由于没有感知到外部变化,并且无法让组织内人员快速学习和执行新的业务规则。
BPM系统的一些特性消除了以上的问题:
A.BPM系统让客户、合作伙伴、供应商参与到流程中来,能够快速直观地获得他们的反馈,感知市场的变化。
B.BPM系统的统计分析工具,能够从历史的数据中,预测到内部外部环境的变化趋势。
C.BPM系统减少了组织内人员对新业务规则的学习成本。
流程执行者不需要知道流程的变化,因为不是由人来触发后续活动,而是由BPM系统根据新的业务规则新的流程定义来触发各个活动。
D.B PM系统要求组织内人员只需要熟悉自己所参与的活动工作即可。
BPM系统如同流水线,分解复杂的工作,让每一个人的工作简化,即使流程发生变化,每个人仍然完成其负责的简单工作。
