DataServices World: Data Services Layer and Its Role In SOA

Mark Davydov's DataServices World Session, June 24, in New York City

The ever-increasing movement towards implementing complex SOA-based applications has triggered a direct attention of leading industry researchers and practitioners to the subject of layering in such applications, in general, and the relationship between the fields of database engineering and SOA, in particular. Common notion of interoperability, loose-coupling between consumers and providers, and complexity-hiding, and demands for enabling extensive reuse of application services to address unforeseen business requirements for new user types, for new types of information and for new composite views has brought to the forefront the concept of Data Services Layer (DSL) as a distinct architectural layer. DSL is an essential part of an application architecture that combines data access functions and corresponding database structures and promises ensuring the next harvest for SOA ROI.

This presentation thoroughly examines the concept of DSL from an architectural and development perspective to reveal significant principles, context, and interrelationships that, in turn, allows focusing on patterns, best practices, design strategies, and proven solutions using the key technologies including semantic models of XML data, XQuery, and popularized SOA-driven commercial and open source database implementations that moved aggressively toward explicit support of SOA, for example, Microsoft SQL Server 2005, IBM DB2 Viper, XAware Open Source 5, and Apache Tuscany.

Speaker Bio: Mark M. Davydov is an internationally recognized expert on software architecture, and software evolution and reuse. Dr. Davydov is the author of over 100 highly acclaimed articles in industry leading publications and vendor technical forums such as IBM developerWorks and Oracle Technical Network. His 2001 book "Corporate Portals and e-Business Integration - A Manager's Guide", introduced many ideas that influenced the progression of Service-Oriented Architecture and the Web Services model. He is a frequent presenter and panel participant at international conferences on software architecture and service-oriented computing, e.g., ICSOC04, WICSA 2004, FinanceCom05, ECIS 2005, WEBIST 2006, etc.

Before his current role as Director of Systems Development at CareFirst Blue Cross Blue Shield and technology advisor to several industry consortiums such as Connected Health and HL7, Dr. Davydov was Vice President and Senior Solutions Architect at Bank of America, where he was responsible for implementing SOA within E-Commerce and Online Banking domains. Prior to joining Bank of America, Dr. Davydov was Chief Architect of Galileo International, and was responsible for developing the Galileo’s platform for interoperable information systems and web portals hosting, a large-scale, high performance, model-driven, service-oriented architecture called “BEST”. Prior to Galileo International, he also held a variety of management positions in both architecture and software development at Fortune 500 corporations. Earlier in his career, Dr. Davydov has taught courses on component-based software engineering and generative programming, and has trained thousands of developers and information technology managers at organizations such as Royal Bank of Canada, Mastercard, and Southwestern Bell. Dr. Davydov did his graduate work in Applied Informatics at the State Academy of Chemical Engineering, and received post-doctoral training in Computer Science at the Karpov Scientific and Research Institute of Physical Chemistry, both in Moscow, Russia.

DataServices World at SOAWorld 2008 (June 24, 2008)

DataServices World (June 24, 2008) is about the confluence of databases, data warehousing, business intelligence, enterprise computing and Internet computing. Its focus is architectures and technologies for accessing data from heterogenous data sources and providing that data to consumers such as components, services and applications.

At DataServices World, chaired by Ken North, we'll uncover architecture and technology solutions for accessing, integrating and processing data from multiple sources while guaranteeing security and scalability. These solutions include robust, high-performance data access middleware, optimized databases, efficient protocol handling, tuned queries and state of the art data services. We'll be looking at technology of interest to CTOs, enterprise architects, system architects, information architects, developers, database gurus, consultants and analysts. Register Early and Save!

SOAWorld Conference & Expo 2008 East
June 23-24, 2008 at the Roosevelt Hotel in New York City
SOA World Conference & Expo 2008 East brings together the best minds in the business for a two-day conference that offers comprehensive coverage of SOA and what it means to enterprise IT today.

Service-oriented architectures have evolved over the past few years out of the original vision of loosely coupled Web services replacing constrained, stovepiped applications throughout enterprise IT. Every major enterprise technology vendor today has developed its own SOA strategy, supported by innumerable mid-size companies and start-ups offering specific SOA aspects or entire solutions.

Service-oriented architectures (SOAs) have evolved over the past few years out of the original vision of loosely coupled web services replacing constrained, stovepiped applications throughout enterprise IT. Every major enterprise technology vendor today has developed its own SOA strategy, supported by innumerable mid-size companies and start-ups offering specific SOA aspects or entire solutions. This explosive growth in SOA technology is in response to a global demand--IDC estimates that spending on SOA services alone will grow from $8.6 billion to more than $33 billion by 2010.
