DataSet: the right tool if well used

(original post)

In the history of programming. Net, no other tool having a climb and fall so fast as noisy as the Dataset. Used as a emblematic item at the early .Net versions, was abused commercially as the solution to all problems of programmers to access and manipulate database. Big mistake, the obvious gap between the development team which created a powerful and versatile object, and the final link with the client (whether msdn or technet) which basically is the visible face to the community of developers and purely commercial court has completely clueless about the skills and dangers of its use. This component is the living example of such a great idea is misleading and manipulated in order to achieve sales, and their way of promotion is an easy way to badly stop the product.
Clearly, not all the fault of the seller, but many times the speed of the market and the decisions on the fly without knowing either the products they mistakenly used the tools. The big problem here is that he blamed the bad component of the publishing being generated or its poor implementation practice, and as the customer is always right, just goes to Microsoft for leaving out the playing field in this component with each new version of Visual Studio, and worse, the solutions are in place as Linq and Entity Data Model not only away from the road, but their benefits are not enough to cover or replace the possibilities offered by DataSet. I will comment on details of usage or best practices in use, and its comparison to highlight the major differences. I just hope to claim their profits before they disappear completely.

Anonymous access in SharePoint

(original post)

Anonymous access is configured during a web site creation  from SharePoint Administration site, which prepares the permissions in IIS.
However, access to lists and pages is restricted in many cases. So we must resort to stsadm command to leave ready access at least.
This is a behavior unwanted, but it was documented by Microsoft with the instructions of the case.
Obviously, the reason for this deficiency is that the product main target for use is under logon or authentication; which makes sense since its main consistent security of access and user management enviroment make it a too robust application to only create (or use their adapted features) with static sites with anonymous access.

UML based State Diagrams

(original post)

The UML (Unified Modeling Language) has a number of extremely useful system tools, essential for any architect or information systems professional needs of application documenting requirements. “States machines” diagrams are part of its behavior modeling, and those who have more evolved from early versions up to the current version of UML 2.2 (-2/2/2009).

The epistemological obstacle as a risk factor in information systems projects

(original post)

Those who treat with the information systems development area, repeatedly found difficulties to develop and deploy a system if either extremely transparent; but for some developers, and/or end-users, meet some difficulties that with a little investigating seems unexplained or quite unjustifiable, and in some cases arbitrary.

Entities and n-tier architecture with Visual Studio

(original post)

Entity Framework

With the last version of Visual Studio 2008 libraries were incorporated to add LINQ and EDM (Entity Data Model) as part of the Framework 3.5 , which apparently offered a more specialized model to work entities. In fact both have classes and specializied namespaces in entities. More natural would seem to be working in these new frameworks, since generating and entities maintaining facilities strongly typed were resolved; knowing that uncomfortable work for n-tier is falling into the trap of creating and maintaining manually countless endless classes or data structures and methods for go translating them as they are moved from the database to the presentation layer; especially if handled messages instead of referenced libraries.

Well, LINQ and EDM not are the panacea of promised happiness.

The information system professionals perspective

(original post)

In the technological world of computer applications, where products are guiding the superior training towards a utilization and ephemeral specialization techniques and languages that are obsolete insofar as these products are marketed, place the profession in information systems rescuing and doing grow the essences and principles which raised it as science is a balance which costs get. This problem is not proprietary within the computing, but are severely exacerbated by the fact that

SharePoint with Silverlight

(this note refers to the SharePoint 2007 and SilverLight 2.0 versions).

Mount Sharepoint based web sites have the direct benefit of saving much time in the effort to develop a custom platform and with the management and security features that are resolved in this product. In a short time can have a standard looking site, and relatively adaptable to different needs

Why a blog?

At the beginning of the new Millennium was installed strongly the concept of “digital identity ” increased significantly in recent years with the proliferation of social networks.” In fact, simple e-mails (type MSN, Yahoo! or Google) added elements of interaction and content that are converting messaging space in a social network like Facebook or Linked In style.
