Welcome to CORPORATE TECHNOLOGY The Three-Tier Architecture Pattern Language Workshop OOPSLA 2001, Tampa Bay, Florida, USA, Marriott Waterside Hotel, Monday, Oct 15, 2001 Software & Engineering Architecture OOPLSA 2001 Workshop 1 © Siemens AG, CT SE 2, Prashant Jain October 15, . 2001

Goal • Capture similarities among three-tier architectures CORPORATE TECHNOLOGY • Describe common requirements and system designs using design patterns • Integrate the design patterns into a pattern language • Share experiences • Just how many layers/tiers are there? • Document best practices as a pattern language Software & Engineering Architecture OOPLSA 2001 Workshop 2 © Siemens AG, CT SE 2, Prashant Jain October 15, . 2001

Reference Questions • Is it really Three-tier or N-tier? • Are there forces specific to each layer? General forces? • Should the patterns be characterized by layers? CORPORATE TECHNOLOGY • What are some of the existing patterns and pattern languages? • What should be the target audience of the pattern language? • How would the pattern language map to specific domains?
