It has become popular in recent years because of its simplicity, conciseness, and clarity. This book teaches functional programming as a way of thinking and problem solving, using Haskell, the most popular purely functional language. Rather than using the conventional (boring) mathematical examples commonly found in other programming language textbooks, the author uses examples drawn from multimedia applications, including graphics, animation, and computer music, thus rewarding the reader with working programs for inherently more interesting applications. Aimed at both beginning and advanced programmers, this tutorial begins with a gentle introduction to functional programming and moves rapidly on to more advanced topics. Details about progamming in Haskell are presented in boxes throughout the text so they can be easily found and referred to.

    On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, author C.J. Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:Should database access granted be through views instead of base tables? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Could you write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports "quantified comparisons," but they're better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don't support them properly. What can you do to resolve this situation? Database theory and practice have evolved since Edgar Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.

    But I don't think I've seen a better resource for the lay user than this one. T. Ormiston-smith. Mother Nature's medicine cabinet. In ancient times, the plant kingdom provided our earliest ancestors with the natural healing powers derived from nature. Extracts and essences from plants and flowers were prized for their medicinal, spiritual, aromatic, and therapeutic value, including beauty benefits. Aromatic plants, essences, and oils have traditionally been used during religious ceremonies and observances, beauty care and perfumes, food enhancement, and preservation. Aromatic plants were the basis for herbal and botanical medicines and remedies for thousands of years - they still are. In fact, they’re the root of today’s modern pharmaceuticals. And as lifestyles rapidly changed to meet everyday challenges, and technology progressed in leaps and bounds, herbal knowledge soon fell by the wayside. During the past century, as the side effects of many chemically based drugs come to light - not to mention the exuberant costs, natural healing has come full circle and has gradually found its way back into our homes. The Western World is standing up and taking notice. People are educating themselves about the wonderful uses and benefits of using essential oils, herbs, and spices. Mother nature's medicine cabinet is back, invoking endless remedies and in some cases, cures - without the side effects. Granted. Natural healing may not replace the family doctor or chemically manufactured drugs entirely, but it certainly is a healthy alternative to consider when thinking about your health, beauty, wellbeing, and fitness regime. Bonus: Includes Medicinal Herbs and their uses. Discover the many benefits to diffusing essential oils to achieve optimal health and well-being in your home and workplace. Diffusing essential oils can help you study better, sleep better, enhance your moods and put you in the mood... Essential oils and pregnancy. Essential oils and children. There is also a section about essential oils for pets – which ones to use and which ones to avoid.
