App Inventor 2 Databases and Files by Edward Mitchell, MS, MBA Pdf

App Inventor 2: Databases and Files is a step-by-step guide to writing apps that use TinyDB, TinyWebDB, Fusion Tables and data files for information storage and retrieval. Includes detailed explanations, examples, and a link to download sample code. This is the first tutorial to cover all of these App Inventor database and file features. If your apps need to work with data or files - you need this book! TinyDB stores data on your smart phone or tablet and is a primary way for App Inventor apps to save data, even when the app is no longer running or if the device is turned off. TinyWebDB is similar to TinyDB, but stores your data on a remote server in the network cloud. Multiple apps can share a TinyWebDB database, plus you can update the content of your TinyWebDB using just a web browser. This means you can distribute an app whose content can change over time - just by changing the values in TinyWebDB. A big challenge is the need to set up a TinyWebDB server - this book shows how to do that through free services offered by Google. Fusion Tables provide a powerful, cloud-based database system for App Inventor apps. Creating, retrieving, updating and deleting data is done using the industry standard Structured Query Language or SQL. Fusion Tables reside in the Google network cloud - this book shows you how to set up and configure Fusion Tables for you own apps using free services of Google. As your app requirements grow, Google's cloud can provide low cost servers and bandwidth for your needs. Underneath the Android OS user interface, there is a file system, similar to the file system found on Windows or Mac OS X. With App Inventor your apps can write and read data from files, and if using the special "CSV" format, App Inventor data can be shared with many spreadsheet programs. This book shows you how to create, use and access data files, and how to convert data to and from the CSV format. Over 28,000 words. Over 250 screen shots and illustrations. Numerous sample programs and code.

App Inventor 2 Advanced Concepts by Edward Mitchell, MS, MBA Pdf

MIT App Inventor 2 is a fast and simple way to create custom Android apps for smart phones or tablets. Volume 2 in the series introduces debugging methods, explains additional controls not covered in Volume 1, introduces “agile” methods for developing a real world app, and provides sample code for using the TinyDB database. This App Inventor 2 series is targeted at adult learners (high school and up). App Inventor 2 provides a simplified “drag and drop” interface to layout your app’s screen design. Then implement the app’s behavior with “drag and drop” programming blocks to quickly assemble a program in a graphical interface. Volume 1 of this series covered the basics of the App Inventor user interface Designer and the Blocks programming editor, plus basic “blocks” programming concepts and tools for arithmetic, text processing, event handling, lists and other features. Volume 2 builds upon Volume 1 to provide tips on debugging programs when the apps work incorrectly, how to us hidden editing features, and how to install your own apps on to your phone or tablet for general use. Code samples are provided for using the Notifier component for general use or for debugging, for user interface control tricks such as buttons that change color continuously or implementing the missing “radio buttons” component, using ListPicker and Spinner for list selections, and using the WebViewer to display web pages in your app. The book includes a large section on designing and building a sample real world application and finishes with a chapter on using the TinyDB database.

Programming the Perl DBI by Tim Bunce,Alligator Descartes Pdf

One of the greatest strengths of the Perl programming language is its ability to manipulate large amounts of data. Database programming is therefore a natural fit for Perl, not only for business applications but also for CGI-based web and intranet applications.The primary interface for database programming in Perl is DBI. DBI is a database-independent package that provides a consistent set of routines regardless of what database product you use--Oracle, Sybase, Ingres, Informix, you name it. The design of DBI is to separate the actual database drivers (DBDs) from the programmer's API, so any DBI program can work with any database, or even with multiple databases by different vendors simultaneously.Programming the Perl DBI is coauthored by Alligator Descartes, one of the most active members of the DBI community, and by Tim Bunce, the inventor of DBI. For the uninitiated, the book explains the architecture of DBI and shows you how to write DBI-based programs. For the experienced DBI dabbler, this book reveals DBI's nuances and the peculiarities of each individual DBD.The book includes: An introduction to DBI and its design How to construct queries and bind parameters Working with database, driver, and statement handles Debugging techniques Coverage of each existing DBD A complete reference to DBI This is the definitive book for database programming in Perl.

Inventor's Manual by Nikolaĭ Rostislavovich Bogatyrev Pdf

"Well presented, practical book, that everybody should have in his pocket" Michel Lecoq (Engineer with 50 years of experience in product, process and business development). Unlike other books that talk about innovation, Inventor's Manual tells you what to do and how to do it in order to achieve the best result faster. Unlike other books on innovation it is ... thin and manageable. It is a lesson with visual appeal, making use of pictures, diagrams and striking examples. This manual can also be helpful for professional trouble-shooters due to its "tick-box" and procedure-like style. The algorithms of the Inventor's Manual are based on a Theory of Inventive Problem Solving (known by its Russian acronym TRIZ), which is a highly adaptable and overarching methodology. But you do not need to know TRIZ to be able to use the Inventor's Manual. The following features make the Inventor's Manual unique: - Step-by-step problem diagnostics and templates for defining the Ideal Final Result which you will not find in any book on TRIZ - Templates for thorough reflection on the context of a product design that are not explicitly presented in TRIZ at all, but which are a very important system thinking aid especially if you are dealing with complex engineering or social system. - "Shortcuts" in the systematic process that allow you to resolve your challenges instantly using simple templates - Inventive Principles have detailed descriptions in connection to the model of the inventive challenges they resolve. You will not find this in any book published on TRIZ - You will find the influence of natural rules for dealing with resources, complexities and ways to avoid problems that are not present in ordinary TRIZ methods. Enjoy your own natural problem-solving talent following the Inventor's Manual!
