{"product_id":"9780134176536","title":"Mastering Data Modeling: A User-Driven Approach","description":"\u003cp\u003eData modeling is one of the most critical phases in the database application development process, but also the phase most likely to fail. A master data modeler must come into any organization, understand its data requirements, and skillfully model the data for applications that most effectively serve organizational needs.\u003c\/p\u003e \u003cp\u003e \u003cbr\u003e \u003c\/p\u003e \u003cp\u003e \u003cb\u003e \u003ci\u003eMastering Data Modeling\u003c\/i\u003e \u003c\/b\u003e is a complete guide to becoming a successful data modeler. Featuring a requirements-driven approach, this book clearly explains fundamental concepts, introduces a user-oriented data modeling notation, and describes a rigorous, step-by-step process for collecting, modeling, and documenting the kinds of data that users need.\u003c\/p\u003e \u003cp\u003e \u003cbr\u003e \u003c\/p\u003e \u003cp\u003eAssuming no prior knowledge, \u003ci\u003e \u003cb\u003eMastering Data Modeling\u003c\/b\u003e \u003c\/i\u003e sets forth several fundamental problems of data modeling, such as reconciling the software developer's demand for rigor with the users' equally valid need to speak their own (sometimes vague) natural language. In addition, it describes the good habits that help you respond to these fundamental problems. With these good habits in mind, the book describes the Logical Data Structure (LDS) notation and the process of controlled evolution by which you can create low-cost, user-approved data models that resist premature obsolescence. Also included is an encyclopedic analysis of all data shapes that you will encounter. Most notably, the book describes The Flow, a loosely scripted process by which you and the users gradually but continuously improve an LDS until it faithfully represents the information needs. Essential implementation and technology issues are also covered. \u003cbr\u003e \u003c\/p\u003e \u003cp\u003e \u003cbr\u003e \u003c\/p\u003e \u003cp\u003e You will learn about such vital topics as: \u003c\/p\u003e \u003cul\u003e \u003cli\u003eThe fundamental problems of data modeling\u003c\/li\u003e \u003cli\u003eThe good habits that help a data modeler be effective and economical\u003c\/li\u003e \u003cli\u003eLDS notation, which encourages these good habits\u003c\/li\u003e \u003cli\u003eHow to read an LDS aloud--in declarative English sentences\u003c\/li\u003e \u003cli\u003eHow to write a well-formed (syntactically correct) LDS\u003c\/li\u003e \u003cli\u003eHow to get users to name the parts of an LDS with words from their own business vocabulary\u003c\/li\u003e \u003cli\u003eHow to visualize data for an LDS\u003c\/li\u003e \u003cli\u003eA catalog of LDS shapes that recur throughout all data models\u003c\/li\u003e \u003cli\u003eThe Flow--the template for your conversations with users\u003c\/li\u003e \u003cli\u003eHow to document an LDS for users, data modelers, and technologists\u003c\/li\u003e \u003cli\u003eHow to map an LDS to a relational schema\u003c\/li\u003e \u003cli\u003eHow LDS differs from other notations and why\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e \"Story interludes\" appear throughout the book, illustrating real-world successes of the LDS notation and controlled evolution process.
