Building the Agile Database by Larry Burns Pdf

Is fast development the enemy of good development? Not necessarily. Agile development requires that databases are designed and built quickly enough to meet fast-based delivery schedules — but in a way that also delivers maximum business value and reuse. How can these requirements both be satisfied? This book, suitable for practitioners at all levels, will explain how to design and build enterprise-quality high-value databases within the constraints of an Agile project. Starting with an overview of the business case for good data management practices, the book defines the various stakeholder groups involved in the software development process, explains the economics of software development (including “time to market” vs. “time to money”), and describes an approach to Agile database development based on the five PRISM principles. This book explains how to work with application developers and other stakeholders, examines critical issues in Agile Development and Data Management, and describes how developers and data professionals can work together to make Agile projects successful while delivering maximum value data to the enterprise. Building the Agile Database will serve as an excellent reference for application developers, data managers, DBAs, project managers, Scrum Masters and IT managers looking to get more value from their development efforts. Among the topics covered: 1. Why Agile is more than just the latest development fad 2. The critical distinction between the logical and physical views of data 3. The importance of data virtualization, and how to achieve it 4. How to eliminate the “object-relational impedance mismatch” 5. The difference between logical modeling and physical design 6. Why databases are more than “persistence engines” 7. When and how to do logical modeling and physical design 8. Use of the logical data model in model-driven development 9. Refactoring made easier 10. Developing an “Agile Attitude”

Relational Databases for Agile Developers by Ron Ballard Pdf

There are many database books; what's special about this one? This book doesn't patronize. There are some technical things to learn about relational databases if you want to use them effectively and this book does not skimp on those. We cover them in detail with practical examples that you can work through. You are not a dummy; you are smart and you are keen to learn. This book doesn't blind you with science. The theory of relational databases can be described in mathematical terms. This is good, but it is not the way people talk about relational databases in projects out there in the business world, in the public sector and in charities. This book uses plain English to describe the concepts and why they are important. This book will help you to communicate with users and colleagues to build great database applications. This book isn't tied to any particular vendor. it discusses all the leading databases, highlighting their similarities and their differences so that you can implement your applications whatever relational database you are using. This book isn't bogged down in bureaucracy. We are enthusiastic about real agile development and we know how to build database applications in an agile team because we have done it, successfully, several times. We do care about doing the job well, testing thoroughly, documenting what needs to be documented, managing frequent releases, but we do not care for the three-inch-thick up-front specification. We have learned some things that make applications successful and some that lead to failure. We share these with you so that you get the best possible opportunity to succeed. We enjoy building database applications and we hope you will too.

Agile Data Warehouse Design by Lawrence Corr,Jim Stagnitto Pdf

Agile Data Warehouse Design is a step-by-step guide for capturing data warehousing/business intelligence (DW/BI) requirements and turning them into high performance dimensional models in the most direct way: by modelstorming (data modeling + brainstorming) with BI stakeholders. This book describes BEAM✲, an agile approach to dimensional modeling, for improving communication between data warehouse designers, BI stakeholders and the whole DW/BI development team. BEAM✲ provides tools and techniques that will encourage DW/BI designers and developers to move away from their keyboards and entity relationship based tools and model interactively with their colleagues. The result is everyone thinks dimensionally from the outset! Developers understand how to efficiently implement dimensional modeling solutions. Business stakeholders feel ownership of the data warehouse they have created, and can already imagine how they will use it to answer their business questions. Within this book, you will learn: ✲ Agile dimensional modeling using Business Event Analysis & Modeling (BEAM✲) ✲ Modelstorming: data modeling that is quicker, more inclusive, more productive, and frankly more fun! ✲ Telling dimensional data stories using the 7Ws (who, what, when, where, how many, why and how) ✲ Modeling by example not abstraction; using data story themes, not crow's feet, to describe detail ✲ Storyboarding the data warehouse to discover conformed dimensions and plan iterative development ✲ Visual modeling: sketching timelines, charts and grids to model complex process measurement - simply ✲ Agile design documentation: enhancing star schemas with BEAM✲ dimensional shorthand notation ✲ Solving difficult DW/BI performance and usability problems with proven dimensional design patterns Lawrence Corr is a data warehouse designer and educator. As Principal of DecisionOne Consulting, he helps clients to review and simplify their data warehouse designs, and advises vendors on visual data modeling techniques. He regularly teaches agile dimensional modeling courses worldwide and has taught dimensional DW/BI skills to thousands of students. Jim Stagnitto is a data warehouse and master data management architect specializing in the healthcare, financial services, and information service industries. He is the founder of the data warehousing and data mining consulting firm Llumino.

Test-Driven Database Development by Max Guernsey III Pdf

The practice of Test-Driven Development (TDD) has helped thousands of software developers improve quality, agility, productivity, and speed. In Test-Driven Database Development, Max Guernsey, III shows how to adapt TDD to achieve the same powerful benefits in database design and development. Guernsey first explains why TDD offers so much potential to database practitioners, and how to overcome obstacles such as the lack of conventional “testable classes.” You’ll learn how to use “classes of databases” to manage change more effectively; how to define testable database behaviors; how to maximize long-term maintainability by limiting a database’s current scope; and how to use “emergent design” to simplify future expansion. Building on this foundation, the author guides you through implementing modern TDD processes and database refactoring. He presents practical techniques for improving legacy databases; for deviating from strict TDD when necessary; and for adapting TDD to applications that persist data in file systems, XML, or serialized objects. Guernsey shows how to • Build a simple infrastructure to track and standardize scripts and databases • Define a sustainable TDD process for database design • Safely change a design without losing data • Design new databases that are lighter, leaner, simpler, more testable, and easier to change • Reduce design costs by eliminating duplication • Gradually bring the benefits of TDD, agility, and modern design to legacy databases • Remediate errors that find their way into database designs • Isolate behaviors and avoid unwanted dependencies that cause tests to fail With this book as a guide, you will learn how to apply the proven practice of TDD to your database needs, and organize and optimize your organization’s data for a significant competitive advantage. Test-Driven Database Development is the newest title in the highly respected NetObjectives Lean-Agile Series.
