Migrating Microsoft Access Applications to SQL Server

Microsoft Access targets individual information workers and small teams that use the Microsoft Office System to track, manage, prioritize, and act upon an increasing volume of business information. The data stored in these databases rarely justifies moving to a more robust platform until the application begins expanding into departmental scenarios. When this happens, it is worthwhile to consider moving the data into a more robust platform for enhanced reliability, scalability, and greater IT control. In most cases, the data can be moved through a process called "upsizing" while the Access application front-end continues to provide information workers with access to critical data. Microsoft has created resources in the following three categories to help manage Access data in your organizations:

But if you like to develop in Access, or don't have any choice, then the tips on this page will help a little to boost your application's performance.

Slowly Changing Dimensions Are Not Always as Easy as 1, 2, 3

To kick off our first column of the year, we're going to take on a challenging subject that all designers face: how to deal with changing dimensions. Unlike most OLTP systems, a major objective of a data warehouse is to track history. So, accounting for change is one of the analyst's most important responsibilities. A sales force region reassignment is a good example of a business change that may require you to alter the dimensional data warehouse. We'll discuss how to apply the right technique to account for the change historically. Hang on to your hats — this is not an easy topic.

Installing and Configuring SQL Server Reporting Services

In this chapter, we discuss various installation setups you can use to install and configure Reporting Services. For the most part, this process is managed by the Setup.exe installation wizard, so expect to be prompted for a number of configuration options that determine how, where, and whether each segment of the Reporting Services package will be installed. We know that there are a variety of ways to install Reporting Services, so we've tried not only to address the common case, but also provide hints and techniques to be used for some of the more sophisticated installation scenarios. To make this process as painless as possible, we've broken this chapter down into several sections:

MDX Essentials: The CROSSJOIN() Function: Breaking Bottlenecks

In this article, we will return to a function we introduced in an earlier article, CROSSJOIN(), whose mission it is to combine two sets of dimension members into one. We will discuss how CROSSJOIN() works in general, and then discuss how its performance can become an issue in medium to large-sized data sets. We will then undertake a multiple-step practice example intended to assist us in gaining an understanding of the issues, before exposing approaches to minimizing the performance overhead that we can encounter in using CROSSJOIN() to reach our reporting and analysis needs.

The HAVING and GROUP BY SQL clauses

This month's topic is one that often baffles inexperienced SQL coders. We will look at the GROUP BY clause, and then the difference between conditions placed in the WHERE clause, and the HAVING clause. I have used MySQL to test all of the examples, but most of them should work without any problems on other DBMS' too.
