PRESIDENT'S MESSAGE |

| Program Director's Message: New technologies bring new opportunities, not just to developers, but also to those of us in the data management profession. Over the past decade, many traditional data management organizations became smaller in size and budget as development groups grow larger. While it is true that attention to web pages, eCommerce, ERP/packaged applications, and Java lead to an increased shift towards developers, I feel a broader reason is because data professionals do not track technology developments the way other technologists do. As a result many of us loose valuable opportunities. My article Leveraging Technology to Reestablish Data Management published in TDAN in October 2006 explores this topic. Also as you can see in the SF DAMA Chapter's Communications Blog the desire to keep data management professionals up on trends in technology has strongly influenced this year's program offerings.

January 10, 2007 Chris Date - The Closed World Assumption - Click to Register ATT San Ramon Facility 2600 Camino Ramon San Ramon, CA 94583 8:30am - Noon  |
Abstract: The Closed World Assumption The Closed World Assumption (CWA) is an important concept in the database world, despite the fact that it isn’t usually spelled out explicitly. Basically what it says is this: Everything stated by the database, either explicitly or implicitly, is true; everything else is false. This presentation explains the CWA in detail and shows why it’s preferred over its rival, the Open World Assumption (OWA). In particular, it examines the claims that are sometimes heard to the effect that the database community operates under the CWA while the semantic web community operates under the OWA. It also explains how "missing information" can be handled under the CWA without any need for nulls or three-valued logic. Topic Outline Background review Relvar predicates and constraints The CWA and OWA defined Relvar predicates revisited Unknown and uncertain information Negation and disjunction Chris Date - Biographical Information C. J. Date is an independent author, lecturer, researcher, and consultant, specializing in relational database technology (a field he helped pioneer). Before leaving IBM in 1983, he was involved in technical planning and design for the IBM products SQL/DS and DB2. His book An Introduction to Database Systems (2004), currently in its 8th edition, is the standard text on the subject; it has sold well over 700,000 copies not counting translations and is used by several hundred colleges and universities worldwide. He is also the author of many other books on database management, including in particular Database, Types, and the Relational Model: The Third Manifesto (Addison-Wesley, 3rd edition, with Hugh Darwen), Temporal Data and the Relational Model (2003, with Hugh Darwen and Nikos A. Lorentzos), The Relational Database Dictionary (O’Reilly, 2006), and Date on Database: Writings 2000-2006 (Apress, 2006). He enjoys a reputation second to none for his ability to explain the complexities of database technology in a clear and simple fashion, both on paper and in live presentations. |

February 7, 2007 Jeff Pekrul, Data Architect, Genentech Inc. |
Designing Canonicals for SOA: Bridging ER and XML Worlds If logical data models reflect the business view, one can think that they would be a strong basis for defining canonical structures to enable service oriented architecture, application agnostic archiving, etc. The challenge lies defining structures that can be implemented in the 'real world', with master data management repositories, inconsistent reference data across applications, and groups that may not agree with names and definitions. This session will be based on actual lessons learnt in seeking to tackle the above, what worked, what did not work, how one can go from an ER model (which is a bidirectional graph) to one or more XML schema structures depending on the technical/business need. Presenter: Jeff Pekrul, Data Architect, Genentech Inc. Jeff Pekrul is a data architect in the Business Solutions Engineering group at Genentech, responsible for canonical model development, and support of data integration projects that use EII technology. Prior to Genentech, Jeff worked as a data modeler/data architect at Charles Schwab, Harmony Software and AT&T. Jeff has modeled databases in support of customer-facing applications in several industries, and has experience with data warehouse modeling as well. Jeff has an MS in Information Systems Management, and is a member of the San Francisco chapter of DAMA. |
