FOR THOSE OF YOU NEW to my earlier book, ADO Examples and Best Practices, it was originally written as an update to my popular Hitchhiker's Guide to Visual Basic and SQL Server, Sixth Edition. Happily, the first edition of ADO Examples and Best Practices received glowing praise from a variety of reviewers, trainers, and devel- opers allover the world. The first edition was not designed as a tutorial on basic ADO; it assumed you had at least some experience with ADO (there are lots of elementary ADO books). In contrast, the Visual Basic version of this new edition adds quite a bit more introductory material to fill in some of the spaces not covered by the introductory books. It also leads the way for developers contem- plating the process of converting existing COM -based ADO code to ADO. NET. ADo. NET and ADO Examples and Best Practices for VB Programmers, Second Edition, focuses on ways to make your applications more efficient and at the same time help you write more efficient code in less time. These efficiencies can make the difference between a successful application (or component orWeb page) and having to spend your weekends fixing its problems. It's been several years since the first edition was published and what Microsoft was going to call "e;Visual Basic 7. 0"e; is still not released to manufac- turing-and it's probably never going to be.

THE HETEROGENEOUS NATURE of software and computing platforms leads to a chaotic and fragile web of code in order to make applications appear seamless to the user while sharing data beneath the surface. Further, the salary that programmers demand to rein in the chaos can tax any company and technology department. Even after an application integration job is complete, the resulting system is often unintelligible and difficult to maintain. Web Services create a common architecture and implementation for exp- ing the application functionality that helps programmers integrate systems and create seamless business processes that span departments, companies, and computing platforms. Web Services are attractive because programmers do not need in-depth knowledge of every computing platform that will participate in a business process. Instead, programmers need to understand Web Services and their own programming environment. As you probably have seen with the object-oriented programming paradigm, the Java 2 Standard Edition (J2SE) computing platform, and even the Java 2 Enterprise Edition (J2EE) computing platform, offering a language, an archit- ture, and a platform to solve problems is not enough. A platform requires an additional layer of organization, known as a pattern, to help realize its full pot- tial. Patterns help you see how to address specific problems with the tools that are available from a computing platform. Web Services are no different from any other computing platform in that the documentation of solutions can help you use the platform better and more quickly.

It is nearly impossible today to write enterprise software without the use of one or more relational databases. Granted, there are cases when the data is transient and not stored in a database, but for the most part, software needs to consume and manipulate data in a database. It sounds easy, but there are hundreds of ways to connect software systems to databases and thousands of people who think they have the skeleton key for data access layers. Pro LINQ Object Relational Mapping in C# 2008 explains an efficient, repeatable way to apply industry design patterns to build scalable object–oriented data access layers.Object relational mapping (OR/M) has been a gray area in Microsoft development for many years. It’s not that Microsoft language developers don’t understand OR/M; in fact, the opposite is true, as is exemplified by the glut of third–party .NET OR/M tools on the market. The struggle has come more from the lack of native tools with the object–oriented and object persistence capacity to effectively work in this arena. With the inception of .NET, Microsoft overcame the first obstacle by developing an object–oriented environment and framework. The second obstacle, the native object persistence layer, is only now being realized with the introduction of Language Integrated Query (LINQ) and LINQ’s children, the Language Integrated Query for Relational Databases (LINQ to SQL) and the Language Integrated Query for the ADO.NET Entity Framework (LINQ to Entities). The gray area no longer exists, and the .NET developers of the world finally have the native tools required to build modular, reusable data access layers.

This brief book explains the advantages of the object model, inheritance, both classical and prototypical, and shows how these concepts can be implemented in JavaScript. It also shows how object programming (OP) opens a new world of design possibilities that go far beyond inheritance.This book will help the intermediate JavaScript programmer learn to use both types of inheritance. For classical inheritance, it is accompanied by a substantial online system (a windowing UI library) that shows classical inheritance at its best. The same system shows how OP "e;capabilities"e; can eliminate much of the need for inheritance. For experienced JavaScript programmers, this book shows why most of the old views of JavaScript's inheritance have not done it justice. JavaScript classes inherit from JavaScript's prototypes, a fact that makes JavaScript's prototypes, when used correctly, functional equivalents to C++ classes (not to prototypes in true prototypical languages, like Self). JavaScript's object programming (not inheritance) is what separates it from classical OOP languages like C++ and Java. Most important, basing inheritance on JavaScript's prototypal chain is possible, but is not the best choice for prototypal inheritance or classical inheritance.What You'll LearnWhat are objects, JavaScript objects and object programmingWhat is and how to use inheritance and JavaScript inheritance as well as inheritance alternativesHow to design for JavaScriptWhat are and how to use OO principles in JavaScriptHow to use Constructors with JavaScript and moreAudienceThis book is for both intermediate and advanced JavaScript and Web development programmers. However, any programmer will understand the concepts and any JavaScript programmer should understand all of the concepts in this book. The code there is shows examples of the concepts discussed.

The introvert is a personality type that draws energy from the outside inward. According to standard personality testing assessments, most people are introverts and no group is more introverted than technical professionals. Introverts are congenitally programmed to recoil from the prospect of public speaking with fear and loathing, yet making presentations to expert and non-expert audiences is an inescapable requirement for career advancement in any technical field. Presentation coach Richard Tierney rides to the rescue of fellow introverts in the IT and engineering sectors with The Introverted Presenter—his fail-safe guide to delivering competent presentations, no matter how unsuited by nature you might be to the performing arts.This short book lays out the complete process guaranteed to raise you from a debilitating state of terror and aversion to a comfortable place of clarity, calm, and competence—perhaps even brilliance, if you can train yourself to convert the free energy of your fear into controlled performance. Tierney repeatedly warns his introvert readers that they risk presentation fiasco if they skip, skimp, or change the order of any of the ten steps he prescribes for thoroughly and efficiently preparing their presentations.The surefire sequence of steps for The Introverted Presenter begins with defining your presentation’s audience and objective. The next step is to write the script of your speech in stages, constructing it on the basis of proven structural rules, cognitive laws, and dramatic tricks. Then you incrementally refine and tighten your script by delivering it iteratively, first in front of a mirror and then in front of increasingly critical test audiences, progressing from your cat to your boss. When you have a well-constructed and sound-tested script in hand and only then, you may create some slides to graft into your script in support of your opening action call and your concluding takeaways, which you commit to memory. Your slides should be limited to the smallest number possible (even zero) and the fewest possible words.

Sawyer shows how to break your company down into basic functional and operational components that can be modeled. The result is a financial model that, for example, you can literally take to the bank or bring to local angel investors to receive the funding you need to launch your business or a new product. Or it might be a model that shows with startling clarity that your new product development effort is a likely winner—or loser. Even better, you’ll learn to create models that will serve as guideposts for ongoing operations. You’ll always know just where you are financially, and where you need to be. The models you will learn to build in Financial Modeling for Business Owners and Entrepreneurs can be used to:Raise capital for startup or any stage of growthPlan projects and new initiativesMake astute business decisions, including go/no-go assessmentsAnalyze ROI on your product development and marketing expendituresStreamline operations, manage budgets, improve efficiency, and reduce costsValue the business when it is time to cash out or mergeIn addition to many valuable exercises and tips for using Excel to model your business, this book contains a combination of practical advice born of hard-won lessons, advanced strategic thought, and the insightful use of hard skills. With a basic knowledge of Excel assumed, it will help you learn to think like an experienced business person who expects to make money on the products or services offered to the public. You’ll discover that the financial model is a key management tool that, if built correctly, provides invaluable assistance every step of the entrepreneurial journey.Tom Y. Sawyer has used the principles this book contains to create financial models of numerous startup and early-stage companies, assisting them in planning for and raising the capital that they needed to grow their businesses and ultimately exit with multiples of their initial investment. Financial Modeling for Business Owners and Entrepreneurs, a mini-MBA in entrepreneurship and finance, will show you how you can do the same.Note: This book is an updated version of Sawyer's 2009 title, Pro Excel Financial Modeling.

Oracle Database Transactions and Locking Revealed provides much-needed information for building scalable, high-concurrency applications and deploy them against the Oracle Database. Read this short, 150-page book that is adapted from Expert Oracle Database Architecture to gain a solid and accurate understanding of how locking and concurrency are dealt with by Oracle Database. Also learn how the Oracle Database architecture accommodates user transactions, and how you can write code to mesh with how Oracle Database is designed to operate.Good transaction design is an important facet of highly-concurrent applications that are run by hundreds, even thousands of users who are all executing transactions at the same time. Transaction design in turn relies upon a good understanding of how the underlying database platform manages of the locking of resources so as to prevent access conflicts and data loss that might otherwise result from concurrent access to data in the database.Oracle Database Transactions and Locking Revealed covers in detail the various lock types, and also different locking schemes such as pessimistic and optimistic locking. Then you’ll learn about transaction isolation and multiversion concurrency, and how the various lock types support Oracle Database’s transactional features. You’ll learn some good tips for transaction design, as well as some bad practices and habits to avoid. Coverage is also given to redo and undo, and their role in concurrency. This is an important book that anyone developing highly-concurrent applications will want to have handy on their shelf.
