The Professional Petroleum Data Management Association (PPDM Association) is a global, not-for-profit organization that works collaboratively within the petroleum industry to create and promote standards and best practices for data management.〔PPDM website (), ''PPDM website'', December, 2011, accessed December 2, 2011.〕 The Association’s vision is the global adoption of data management standards and best practices throughout the upstream (exploration and production) petroleum industry. The focus of the Association is: * Continued development and support of the PPDM data model * Standard or baseline definitions of essential terminology * Best practices for developing a data governance strategy * Education and training around data management standards * Certification for E&P (exploration and production) data management professionals. ==PPDM and the Need to Organize Petroleum Data== Historically, petroleum data has been managed and analyzed using many different proprietary systems. These systems are typically built based on local terminology and business needs, and use different practices for identifying, gathering, transferring and interpreting information. A typical operating company may use dozens (or even hundreds) of software applications. Each department is tuned to the needs of different segments of the company; production accounting, field operations, seismic exploration, reserves management and financial departments all store information about wells in their respective software applications.〔First Break Magazine (), ''First Break'', January, 2005, accessed January 19, 2011.〕 In 1989, one Calgary-based oil company and several of its software suppliers recognized that a non-proprietary data model was preferable to separate and private models. The creation of a comprehensive data model is an expensive and lengthy process. A private data model precludes the purchase of third-party software and other data-dependent services, without expensive customization. Therefore, a group of technical experts began work on a “public” model, and other companies responded to the invitation to participate. As the model developed, more companies accepted the concept of non-competitive collaboration and recognized that there is little competitive advantage to using an exclusive private data model. In 1991 the cooperative workgroup was incorporated in Alberta as a not-for-profit society, the Public Petroleum Data Model Association. The initial data modeling efforts were on the requirements for well data in a relational database management system. Throughout the 1990s, the scope expanded to land rights, seismic surveys, well production and reserves, stratigraphy, records management, etc. Version 3.8 of the PPDM Model, released in 2008, covers 53 subject areas and has over 1700 tables. In 2008, the name was changed to the Professional Petroleum Data Management Association. This acknowledges the expansion of the products and services beyond just the data model, and emphasizes the focus on developing the professional practice of data management for the petroleum industry. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Professional Petroleum Data Management Association」の詳細全文を読む スポンサード リンク
