Implementation

Software Expert Kent Beck Presents a Catalog of Patterns Infinitely Useful for Everyday Programming Great code doesn’t just function: it clearly and consistently communicates your intentions, allowing other programmers to understand your code, rely on it, and modify it with confidence. But great code doesn’t just happen. It is the outcome of hundreds of small but critical decisions programmers make every single day. Now, legendary software innovator Kent Beck—known worldwide for creating Extreme Programming and pioneering software patterns and test-driven development—focuses on these critical decisions, unearthing powerful “implementation patterns” for writing programs that are simpler, clearer, better organized, and more cost effective. Beck collects 77 patterns for handling everyday programming tasks and writing more readable code. This new collection of patterns addresses many aspects of development, including class, state, behavior, method, collections, frameworks, and more. He uses diagrams, stories, examples, and essays to engage the reader as he illuminates the patterns. You’ll find proven solutions for handling everything from naming variables to checking exceptions.

This textbook examines database systems from the viewpoint of a software developer. This perspective makes it possible to investigate why database systems are the way they are. It is of course important to be able to write queries, but it is equally important to know how they are processed. We e.g. don’t want to just use JDBC; we also want to know why the API contains the classes and methods that it does. We need a sense of how hard is it to write a disk cache or logging facility. And what exactly is a database driver, anyway? The first two chapters provide a brief overview of database systems and their use. Chapter 1 discusses the purpose and features of a database system and introduces the Derby and SimpleDB systems. Chapter 2 explains how to write a database application using Java. It presents the basics of JDBC, which is the fundamental API for Java programs that interact with a database. In turn, Chapters 3-11 examine the internals of a typical database engine. Each chapter covers a different database component, starting with the lowest level of abstraction (the disk and file manager) and ending with the highest (the JDBC client interface); further, the respective chapter explains the main issues concerning the component, and considers possible design decisions. As a result, the reader can see exactly what services each component provides and how it interacts with the other components in the system. By the end of this part, s/he will have witnessed the gradual development of a simple but completely functional system. The remaining four chapters then focus on efficient query processing, and focus on the sophisticated techniques and algorithms that can replace the simple design choices described earlier. Topics include indexing, sorting, intelligent buffer usage, and query optimization. This text is intended for upper-level undergraduate or beginning graduate courses in Computer Science. It assumes that the reader is comfortable with basic Java programming; advanced Java concepts (such as RMI and JDBC) are fully explained in the text. The respective chapters are complemented by “end-of-chapter readings” that discuss interesting ideas and research directions that went unmentioned in the text, and provide references to relevant web pages, research articles, reference manuals, and books. Conceptual and programming exercises are also included at the end of each chapter. Students can apply their conceptual knowledge by examining the SimpleDB (a simple but fully functional database system created by the author and provided online) code and modifying it.

This book confronts the widespread impression that policy or program implementation should be easy, arguing instead that implementation, even under the best of circumstances, is exceedingly difficult. Using the Oakland Project as a case study, this book discusses each stage of the process of implementation, demonstrating that completion of what might seem to be a simple sequence of events will in fact depend on a complex chain of reciprocal interactions. Each part of the chain must be built with the others in view, so the separation of policy design from implementation is fatal. The first four chapters illustrate the movement from simplicity to complexity. Chapter 5 discusses the number of decision points throughout the process, giving an indication of the magnitude of the task. Chapter 6 examines why project targets may be set even if they are unlikely to be met, considering both the position of those who set targets -- top federal officials who wish large accomplishments from small resources in a short time -- and those who must implement them -- career bureaucrats and local participants characterized by high needs and low cohesion. The last chapter discusses the relationship between the evaluation of programs and the study of their implementation, arguing that tendencies to assimilate the two should be resisted.

Many strategies fail not because they are improperly formulated but because they are poorly implemented. The Oxford Handbook of Strategy Implementation examines the crucial role of implementation in how business and managerial strategies produce returns. In this wide-ranging collection of essays, leading scholars address governance, resources, human capital, and accounting-based control systems, advancing our understanding of strategy implementation and identifying opportunities for future research on this important process.

Harness the power of collective efficacy to achieve quality implementation! Designed to overcome the biggest barriers to quality implementation and, thus, school improvement and student achievement, this book unpacks the powerful force of collective efficacy. The authors examine how this shared belief that the combined efforts of faculty members can positively influence student outcomes, is instrumental to establishing evidence-based practices for lasting change. In addition to a helpful conceptual framework to visualize key components, readers will discover: • Ways to create environments that tap into mastery as the number one source of collective efficacy • Methods to strengthen vicarious experiences through observational learning • Examination of social persuasion and affective states as additional sources of collective efficacy

Project Management Implementation as Management Innovation: A Closer Look investigates the processes involved in implementing one particular type of management innovation—project management—and how these innovations must evolve and be modified in order to deliver value. The book was written by three internationally recognized project management researchers/practitioners. Their extensive experience in the classroom and in the field shows through in how they are able to present complex concepts and make them highly relevant to project managers of all levels. Project Management Implementation as Management Innovation: A Closer Look begins by exploring the book's key concepts, including “innovation events,” “intervention,” and “simple” and “complex” innovation journeys.

This paper reviews the implementation of the “2018 Framework for Enhanced Fund Engagement on Governance” (the “2018 Governance Framework”). The Board adopted the 2018 Governance Framework to promote a more systematic, effective, candid, and evenhanded engagement with member countries regarding corruption of macro critical dimensions and governance vulnerabilities that allow corruption. Building upon various sources of information, including surveys with key stakeholders, the paper provides a comprehensive stocktaking of the Fund’s work in governance and corruption since 2018, and makes specific proposals to further improve implementation of the Framework.
