Active Directory (AD) failure, which includes corruption, is something that is dreaded by any administrator. Simply put, it means that the directory service can no longer read the Active Directory database that it has locally. This will prevent logon and authentication as well as any directory-dependent services. Essentially, it renders the domain controller (DC) useless. What's worse, though, is that several times, the replication keeps going so that the corrupted database spreads out to the other DCs.
In this article by Florian Rommel, we will look at the different options and approaches available to recover a DC that has a database corruption. In addition, this article outlines, symptoms, causes, and solutions for this scenario.Read How to Recover from an Active Directory Failure in full
Planning is a key element of any IT implementation, but planning can only be accomplished with an understanding of the technical underpinnings of the proposed solution. In this article, authors Mitesh Desai and Dan Renfroe delve more deeply into the technical architecture of BES in order to provide you with an understanding of what’s under the hood. This article also covers the system requirements and pre-requisites for a BES implementation, including operating system, hardware, network, and database requirements.Read BlackBerry: BES Architecture and Implementation Planning in full
LINQ to Objects means that we can use LINQ to query objects in a collection. We can access the in-memory data structures using LINQ. We can query any type of object that implements the IEnumerable interface or IEnumerable
In this article, author N. Satheesh Kumar shows us how to query different objects using LINQ operators and avoid having to use the looping method to filter the values in a collection.Read LINQ to Objects in full
Once we have the data view firmly embedded in our page, it is a breeze to change the way the data looks and operates. In this article by Mike Poole, we will learn to apply nice formatting to data that is displayed on our page. We will learn to do this by making use of Cascading Style Sheets. We will also learn how to format our data automatically, depending on the data values (a technique known as conditional formatting). Then we will learn to filter and sort our data, use formulae to perform calculations, and how to split our data up into multiple pages.Read SharePoint: Displaying Data in full
In the previous part of the article, we had a look at the Report Builder overview and described the Report Builder 2.0 interface. In this part by Jayaram Krishnaswamy, we will discuss about Enabling and reviewing My Reports, and will see how to Modify a basic report.Read Working with the Report Builder in Microsoft SQL Server 2008: Part 2 in full
As noted in Part 1, OLAP presents Business Intelligence via what is known as a CUBE. A Cube has many dimensions and it provides a faster method to access the intelligence compared to the structured querying where the overhead of 'Joins' makes it inefficient. Taking the example of a 'Sales' Cube having everything related to sales we can identify the dimensions as the Sales Outlet, The Customers , the Products and the time period over which sales are being audited or looked into. We also notice that there are certain measures that we are interested related to these 'dimensions' like 'Store Sales', 'Cost of Products, 'number of units sold' etc. The Analysis Services analyzes these intricate relationship that exist in a cube. In this part we will see the process of creating a Cube in VS 2008.Read Creating an Analysis Services Cube with Visual Studio 2008 - Part 2 in full
Microsoft Windows Mobile Platform is now fully supported with .NET technology. We can develop and deploy .NET-based applications directly on to smart devices enabled with Microsoft Windows Mobile operating system.This article by Jagadish Chatarji Pulakhandam and Sunitha Paruchuri shows an example of deploying such an application.Read Deploying .NET-based Applications on to Microsoft Windows CE Enabled Smart Devices in full
A cube in the context of Business Intelligence is a multidimensional representation of business facts that can be accessed quickly to provide specific information. (This can be accomplished by properly written queries in a relational database, but the overhead involved in processing the query, which may involve a large number of 'joins', is simply not efficient). While a relational model is more suited to OLTP, a different model is necessary for OLAP. Whereas highly normalized tables are a norm for OLTP, the model for OLAP does not require normalization. The SQL Server Analysis Services that supersedes the earlier versions is specifically meant for analyzing data in the archives or in OLTP databases to be retrieved and burnished to provide the 'Intelligence' by mining for facts hidden in the data. This two part article by Dr. Jayaram Krishnaswamy describes how a Cube is designed using Visual Studio 2008 and how it may be browsed on the Analysis Server. In Part 1, the necessary items for creating the Cube, namely the Data Source and Data Source Views are described.Read Creating an Analysis Services Cube with Visual Studio 2008 - Part 1 in full
In this article by Alexandru Serban, let's take a more realistic software development scenario. What I am going to build is a room-reservation system for the newly launched Orbital Hotel. As you well know, this is the very first space building, after the International Space Station, used for tourism, allowing people to enjoy a view of our blue planet and stars from their private rooms. OK, OK, the Orbital Hotel doesn't yet exist, but when it does, it must have a room reservation system anyway. Who knows, it might be this one.Read Visual SourceSafe:Creating a Service-Oriented Application in full
Developing AJAX applications that involve complex client-side programming and communication with the server side raises the need for equally complex debugging tools and techniques.
Most of today’s AJAX frameworks, including the Microsoft AJAX Library, offer built-in capabilities for debugging and tracing.
In this article by Cristian Darie and Bogdan Brinzarea, we will learn about the capabilities built in the Microsoft AJAX Library, and we’ll also learn about third-party debugging and tracing tools.Read Debugging AJAX using Microsoft AJAX Library, Internet Explorer and Mozilla Firefox in full
