In this paper we will consider the need for, and benefits of, implementing information architecture and we will discuss how Sybase PowerDesigner, Version 16, enables that process. Briefly, Sybase PowerDesigner has 20+ years history of providing modelling support for database design and has more recently introduced support for enterprise architecture. With version 16 the company has added a focus on information architecture, which introduces a set of information architecture models for a range of stakeholders from data analysts to business analysts around a single metadata repository. Its "Link and Synch" facility keeps all the models in synch, regardless of which one a particular stakeholder feels comfortable with updating, without compromising the individual models with inappropriate data. For example, a logical model is transformed into a new physical model and the data needed for physical implementation is added during transformation, instead of cluttering the logical model up with inappropriate physical in formation, thus enabling logical designers and analysts and physical implementers to work efficiently with appropriate visualisations.
