Forget what you think you may know about COBOL. Even though the language is more than 50 years old, COBOL applications still reign in the world of enterprise IT. With billions of transactions executed every day and often running behind the scenes, COBOL systems touch many aspects of our daily lives. Your mission: To start a new era of innovation powered by modern tools that bridge COBOL systems to the world of Java and .NET. Brought to you by Micro Focus (www.microfocus.com), the leader in COBOL development tools, this book is written for the COBOL, Java and .NET developer. Key features include: A simplified real-world example to illustrate key concepts; an explanation of the .NET and Java object models for the COBOL developer; an introduction to COBOL for the Java or .NET developer; a complete reference to the new syntax for Visual COBOL; and a free student development tools license integrated within Visual Studio and Eclipse. The author, Paul Kelly, has worked at Micro Focus for over twenty years. He started as a technical author before moving into software development. Paul worked on Visual COBOL for 10 years between 2002 and 2012, initially on Visual Studio development, then later on Eclipse, before changing roles again to work as an architect developing a cloud-based SaaS offering for Micro Focus.

Limitations in today's software packages for financial modeling system development can threaten the viability of any system--not to mention the firm using that system. Modeling Financial Markets is the first book to take financial professionals beyond those limitations to introduce safer, more sophisticated modeling methods. It contains dozens of techniques for financial modeling in code that minimize or avoid current software deficiencies, and addresses the crucial crossover stage in which prototypes are converted to fully coded models.
This book teaches everything you need for developing web applications with ASP.NET. Along the way, you'll learn how to use server controls, validation controls, site navigation, state management, and ADO.NET database programming techniques including datasets, caching, binding, and the DataList and DataGrid controls. You'll also learn how to secure your ASP.NET pages, how to create and use XML web services, how to create and use custom server controls and user controls, how to incorporate Crystal Reports into your web applications, and how to deploy a web application. Although all of the examples use VB.NET as the programming language, ASP.NET works the same no matter what language you use.
