English Steering and Supporting Search Engine Crawling

Since Google launched the sitemap protocol in June 2005, webmasters and search engine optimizers have to rethink their dealing with search engine crawlers. Assuming Google will remove the sitemap protocol's 'beta' label faster than from it's search engine, this article tries to give web site owners an idea where to place Google sitemaps in their toolset. To define the playground, this article starts as a tutorial on supporting and steering search engine crawlers.

English SEO is dead - Long live SEO!

Webmasters and search engine optimizers tend to discuss Google updates to death, trying to extrapolate supposed changes in Google's ranking algorithm from selfish rants of disappointed site owners. Every major update results in thousands of posts. 99.99% of them are totally pointless. GoogleGuy fills the 0.01% trying to set the records straight, usually vainly. Savvy oldtimers ignore this waste of time and space, but -unexplainably and surely not driven by common sense- zillions of webmasters do make changes based on assumptions in these soap operas. After Google's bourbon update (May/June 2005) Liane wrote this great call for rationality.

English How to Make Use of Google SiteMaps

In June 2005, Google® has launched a service called Google® SiteMaps to optimize Googlebot's web site crawling. It allows webmasters to submit new/modified URLs to Google's spider Googlebot. Google SiteMap submissions have no impact on rankings on Google's SERPs nor will they influence PageRank™ calculations, but most probably they will help webmasters to get their new stuff crawled by Googlebot faster than before. Although we can't predict how or how much this new service, which is still in BETA state, will help site owners, we tell you how to make use of Google SiteMaps. [Update July 2005: It works like a charm. It even works better than expected. It improves search engine visibility to a great degree, as long as webmasters care what they submit to Google.]

English Database Debunkings

Fabian Pascal and C.J. Date made up this web site that sets matters straight by telling the truth about database management. It is the critical forum for concepts, principles and methods and their practical implications that receive little, incorrect, or no coverage from the trade media, and no consideration from vendors and industry pundits. It is dedicated to and intended for MIS professionals, application developers, managers, users (experienced or novices), academics and students who think for themselves, want to understand database management, rather than follow the prevailing "cookbook" approach, and who are interested in minimizing the severe costs imposed by mindless technology and marketing fads. The site is focused on database education--as distinct from product-specific training--and should be, therefore, useful, regardless of DBMS software or technology is used.

You can use it to add languages to your application to reach global markets, to expand your base of users in your local market, or to customize applications for individual clients. If you struggle with maintaining homebrew localization tools and processes, or have projects that have outgrown Progress Translation Manager, WizTom can relieve you of unwieldy localization processess and bring you to a modern and supported methodology.

English XenCraft's Word Parser for Progress Software® Users

The XenCraft Word Parser for Progress (XenWORD) is a shared library that parses text into words using the Progress word rules table, the same rules used for database word indexes. This gives developers and users the ability to review how the text is being parsed, to confirm the correct rules are being used or to experiment with new rules. The library can also be used more generally for text parsing and manipulation.

English Crawlers, Spiders, Web Robots ...

Everything you need to know about web bots, aka spiders, aka crawlers. Robots Exclusion: How to use robots.txt and robots meta tags to prevent directories and/or particular pages from crawling/indexing. Identifying Robots: Not every user_agent points to the responsible web service by its name. 'Googlebots' does. 'Slurp' (Inktomi spider), 'Robozilla' (DMOZ link checker) or 'Scooter' (Altavista crawler) don't. Martijn Koster's web robot directory provides at least the legitimate bots, along with interesting articles, links and more. Also visit Jafsoft's Search Engine Robots page, where you'll even find the IP addresses of many search engine crawlers and other spiders. Learn here how to block fraudulent bots, email harvesters, grabber like 'teleport', 'webcapture', 'webcopier' and other unwanted accesses to your web site.

English Encrypting Data In Your 4GL Application and Database

Your database is being accessed from the wilds. Usually that refers to the internet – where there are people working on connections to your machines to achieve something. Sometimes it is to place an order. Sometimes it is to pull all the credit card numbers out of your system!
How can you protect yourself from someone logging into your database via an ODBC 'password flinger' and having free reign of the data? How can you protect yourself from the collection of viruses that would like to make use of your Windows computer to go wandering around your data?

English The Dynamic WebClient® Platform

The Progress® WebClient® product is a major addition to the Progress® Software Corporation product line. WebClient® enables the development of true 'thin client' applications to be distributed, deployed and maintained over networks without ever doing any work on the client machine. The automatic deployment and update mechanism supports and implements the Application Service Provider (ASP) model where end users 'rent' applications on a pay-as-you-go basis and are automatically ensured of running the latest version of the application.
When organizations started deploying their WebClient® applications over the internet significant performance bottlenecks became apparent. While the applications do have acceptable performance over Local Area Networks and Intranets, traditional Progress® development environments prove to be too slow for delivery over the public internet, often still accessed by users through dial-up modems. When faced with the task of providing thousands of dial-up users access to central databases over the internet, Netsetup quickly recognized that an entirely new architecture was required to achieve this goal.
Extensive measurements revealed that traditional Progress® architectures suffer from three major bottlenecks when faced with internet deployment: too many AppServer calls, excessive data exchange, and large r-code deployment to the client.
The Dynamic WebClient® Architecture is based on the union of a single 'Business Logic' object on the server and a single 'User Interface' object on the client. Together, these two objects are capable of delivering full-blown Windows applications to the end user with sub-second response times over dial-up internet connections.
The use of bandwidth is typically much lower than a comparable HTML-based web application. A single user interaction results in just a single AppServer call, even if that interaction returns a screen full of browser and viewer data. Due to the stateless architecture a single application server can support thousands of concurrent users.
As a matter of fact, with the Dynamic WebClient® Architecture you do not have to wait for UMTS frequencies to become available to provide wireless access to your Progress® applications; a standard GPRS connection is sufficient to run DWA applications on your laptop. Even a 9.600 baud GSM connection can be used to access DWA applications from anywhere in the world. This claim leaves the major industry players out in the cold.
A development team led by internationally renowned Progress specialist Peter van Dam was instituted to develop a new WebClient® architecture for the internet.
The answer was found in the combination of a completely 'dynamic' approach, highly compressed intelligent data transfer, sophisticated caching techniques, and the use of a central repository to store application definitions.
Stateless AppServers ensure virtually unlimited scalability. The result is an internet deployment architecture for Windows applications with unparalleled performance: the Dynamic WebClient® Architecture.
The Dynamic WebClient® Platform is the development environment for applications based on the Dynamic WebClient® Architecture. This environment enables developers to rapidly (re)develop Progress® based Windows applications for deployment over the internet.
Using the Dynamic WebClient® Platform does not mean that the existing applications are to be completely rewritten. Often it is sufficient to redevelop specific key parts of the front-end, leaving the rest of the application intact.
