It includes an advanced but extremely easy to use Ajax Framework, allowing sophisticated, modern web applications to be built almost as quickly and simply as static web pages. EWD has been designed to be technology-independent, and is potentially capable of working with any web application front-end environment (eg PHP, Java Server Pages, ASP.Net), any scripting language and any database.

Businesses currently face the daily challenge of managing content efficiently. These businesses are being flooded with information from web Content Management Systems (CMS) that present an all-too-simple picture. Instead, content management systems should solve the problem of turning content into information and information into knowledge.

Content Management Systems are not just a product or a technology. CMS is defined as a generic term which refers to a wide range of processes that underpin the “next-generation” of medium to large-scale websites. Content management is a process which deals with the creation, storage, modification, retrieval and display of data or content.

A number of new geospatial viewing tools from major players in the Internet industry have recently appeared on the scene and are taking the geospatial world by storm. Google,Yahoo, Microsoft, and Amazon have all released web-based mapping tools in the recent past, and collectively these new players to the industry have raised the bar for Internet mapping. Although their functional capabilities don’t provide anything we haven’t seen in web offerings from traditional GIS vendors, their emergence has been significant in that they have managed to capture a wider audience. Google, in particular, has emerged as the leader of this pack with it’s recently released Google Maps product which provides a slick, highly responsive visual interface built using AJAX technologies along with detailed street and aerial imagery data, and an open API allowing customization of the map output including the ability to add application specific data to the map.

BioTeam first became interested in Univa UD’s software efforts after hearing Univa CTO Steve Tueckespeak in Regensburg, Germany at the 2007 Grid Engine workshop. Shortly after that event Univa formally became Univa UD after merging with United Devices. At the time, Steve’s company seemed to be one of the few companies positioning themselves to offer full support and professional services encompassing commonly used open source products such as Sun Grid Engine that BioTeam often works with in the field. Individually these popular open source resources are relatively easy to acquire but Univa UD seemed to be making an interesting effort to become the one stop shop for a fully supported and integrated set of commonly required tools and technology.

Many developers have learned to use PHP over the years because it’s a good solution for creat- ing Web pages and the price is right. The PHP acronym is like many other new acronyms for the Internet—the acronym is recursive (refers back to itself). PHP stands for PHP Hypertext Processor. This general-purpose HTML scripting language works much like ASP (see Chapter 6) or other page description languages you might have used. Essentially, you mix HTML with scripting information. When the PHP process sees HTML, it sends the text directly to the user. It processes any scripting information, and passes the resulting HTML to the user as well.

So - you are wrapping up development of yet another Web app. The database is in place, CRUD functions are working, user interface and reports have been signed off. Now your thoughts are turning to access control. Just enough time to splice in that trusty user authentication and roles module, make a few tweaks and move on to the next project. Wait! Do you really want to contribute yet another authorization stovepipe to the growing forest? We all curse the proliferation of authentication and authorization “solutions” on the Web. Yet we continue to treat access control as an after thought.

This How To shows you how to create and configure a custom least-privileged service account to run an ASP.NET Web application. By default, an ASP.NET application on Microsoft Windows Server 2003 and IIS 6.0 runs using the built-in Network Service account. In production environments, you usually run your application using a custom service account. By using a custom service account, you can audit and authorize your application separately from others, and your application is protected from any changes made to the privileges or permissions associated with the Network Service account. To use a custom service account, you must configure the account by running the Aspnet_regiis.exe utility with the -ga switch, and then configure your application to run in a custom application pool that uses the custom account’s identity.
