Beginning Programming All-in-One Desk Reference For Dummies


Book Description

The fun, fast, and easy way to learn programming fundamentals and essentials – from C to Visual Basic and all the languages in between So you want to be a programmer? Or maybe you just want to make your computer do what YOU want for a change? Maybe you enjoy the challenge of identifying a problem and solving it. If programming intrigues you (for whatever reason), Beginning Programming All-In-One Desk Reference For Dummies is like having a starter programming library all in one handy, if hefty, book. In this practical guide, you'll find out about algorithms, best practices, compiling, debugging your programs, and much more. The concepts are illustrated in several different programming languages, so you'll get a feel for the variety of languages and the needs they fill. Inside you'll discover seven minibooks: Getting Started: From learning methods for writing programs to becoming familiar with types of programming languages, you'll lay the foundation for your programming adventure with this minibook. Programming Basics: Here you’ll dive into how programs work, variables, data types, branching, looping, subprograms, objects, and more. Data Structures: From structures, arrays, sets, linked lists, and collections, to stacks, queues, graphs, and trees, you'll dig deeply into the data. Algorithms: This minibook shows you how to sort and search algorithms, how to use string searching, and gets into data compression and encryption. Web Programming: Learn everything you need to know about coding for the web: HyperText. Markup Language (better known simply as HTML), CSS, JavaScript, PHP, and Ruby. Programming Language Syntax: Introduces you to the syntax of various languages – C, C++, Java, C#, Perl, Python, Pascal, Delphi, Visual Basic, REALbasic – so you know when to use which one. Applications: This is the fun part where you put your newly developed programming skills to work in practical ways. Additionally, Beginning Programming All-In-One Desk Reference For Dummies shows you how to decide what you want your program to do, turn your instructions into "machine language" that the computer understands, use programming best practices, explore the "how" and "why" of data structuring, and more. And you'll get a look into various applications like database management, bioinformatics, computer security, and artificial intelligence. After you get this book and start coding, you'll soon realize that — wow! You're a programmer!




Database Processing with Fourth Generation Languages


Book Description

This text is intended to provide a greater depth of coverage of data languages than is currently available. These languages have been colloquially called "fourth generation languages" available in a large number of commercial products. The book is structured around the basic principles that tend to be common to the majority of these products. Relational database theory, along with relational languages and their various commercial implementations, visual programming and integrated programming environments are covered in some depth. This book is intended for business students who have had at least one course in a traditional programming language (COBOL, BASIC, etc.) without any other prerequisites.







Standard Relational and Network Database Languages


Book Description

For any type of software to become standard, whether a third genera tion language or an integrated project support environment (IPSE), it must undergo a series of modifications and updates which are a direct result of theoretical and empirical knowledge gained in the process. The database approach to the design of general purpose infonn ation systems has undergone a series of revisions during the last twenty years which have established it as a winner in many different spheres of infonnation processing, including expert systems and real time control. It is now widely recognised by academics and practitioners alike, that the use of a database management system (DBMS) as the under lying software tool for the development of infonnation/knowledge based systems can lead to environments which are: (a) flexible, (b) efficient, (c) user-friendly, (d) free from duplication, and (e) fully controllable. The concept of a DBMS is now mature and has produced the software necessary to design the actual database holding the data. The database languages proposed recently by the International Organisa tion for Standardisation (ISO) are thorough enough for the design of the necessary software compilers (i.e programs which translate the high level commands into machine language for fast execution by the computer hardware). The ISO languages adopt two basic models of data and therefore two different sets of commands: (a) the relational, implemented via the relational database language (RDL), and (b) the network, imple mented via the network database language (NDL).

An authoritative reference to the most widely-used database management programming language.




Harry Markowitz: Selected Works


Book Description

Harry M Markowitz received the Nobel Prize in Economics in 1990 for his pioneering work in portfolio theory. He also received the von Neumann Prize from the Institute of Management Science and the Operations Research Institute of America in 1989 for his work in portfolio theory, sparse matrices and the SIMSCRIPT computer language. While Dr Markowitz is well-known for his work on portfolio theory, his work on sparse matrices remains an essential part of linear optimization calculations. In addition, he designed and developed SIMSCRIPT — a computer programming language. SIMSCRIPT has been widely used for simulations of systems such as air transportation and communication networks.This book consists of a collection of Dr Markowitz's most important works in these and other fields.
