Plus, there are new data mart designs, including financial analysis, inventory management, and shipping logistics. With this book, you'll learn how to: Customize enterprise and logical data models that meet the specific needs of your organization Convert logical data models to data warehouses and data marts Develop physical data designs and evaluate design options based on the universal data models Integrate databases and data ware- houses across the enterprise Validate your organization's existing data models You'll also want to check out the companion volume, The Data Model Resource Book, Revised Edition, Volume 2 , which provides universal data models that have been tailored for various industries and applications. It does not merely address the top levels of a data architecture Zachman Framework row one or two ; it provides both common and industry-specific logical models as well as data designs that may be customized to meet your requirements. The end result is a is a rich framework whose models span the higher and lower levels of a data architecture, including high-level models, logical models, warehouse designs, star schemas, and SQL scripts. You can use the data models, designs, and scripts as templates or starting points for your own modeling, an introduction to subject areas you might not be familiar with, a reference to validate your existing models, and a help to building an enterprise data architecture. The book provides techniques to transform models from one level to another, as well as tips and techniques for getting the appropriate levels of abstraction in the models.

    The Data Model Resource Book, Volume 3: Universal Patterns for Data Modeling [Book]

    The Remote Sensing Data Book. Len Silverston and Paul Agnewhave provided an indispensable reference of very high-quality patterns for the most foundational types of datamodel structures.

    This book represents a revolutionary leap in moving the data modeling profession forward. Len Silverston and Paul Agnew have created a valuable addition to our field, allowing us to improve the consistency and quality of our models by leveraging the many common structures within this text.

    The patterns have found their way into the core of our Enterprise Information Model, our data warehouse designs, and progressively into key business function databases. We are getting to reuse the patterns across projects and are reaping benefits in understanding, flexibility, and time-to-market.

    Thanks so much. Data models become stable, but remain very flexible to accommodate changes. These data modeling design patterns have helped us to focus on the essential business issues because we have leveraged these reusable building blocks for many of the standard design problems. These design patterns have also helped us to evaluate the quality of data models for their intended purpose.

    They may also constrain the business rather than support it. A major cause is that the quality of the data models implemented in systems and interfaces is poor". This means that small changes in the way business is conducted lead to large changes in computer systems and interfaces".

    This can lead to replication of data, data structure, and functionality, together with the attendant costs of that duplication in development and maintenance".

    The result of this is that complex interfaces are required between systems that share data. For example, engineering design data and drawings for process plant are still sometimes exchanged on paper".

    Typical applications of data models include database models, design of information systems, and enabling exchange of data. Usually data models are specified in a data modeling language. This shows that a data model can be an external model or view , a conceptual model, or a physical model.

    This is not the only way to look at data models, but it is a useful way, particularly when comparing models. For example, it may be a model of the interest area of an organization or industry.

    This consists of entity classes, representing kinds of things of significance in the domain, and relationship assertions about associations between pairs of entity classes.

    A conceptual schema specifies the kinds of facts or propositions that can be expressed using the model. In that sense, it defines the allowed expressions in an artificial 'language' with a scope that is limited by the scope of the model.

    This consists of descriptions of tables and columns, object oriented classes, and XML tags, among other things. This is concerned with partitions, CPUs, tablespaces, and the like.
