Clustering for Indexes

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.

Easy Package Configuration

One of the age old problems in DTS is moving packages between your development, test and production environments. Typically a series of manual edits needs to be done to all the packages to make sure that all the connection objects are pointing to the correct physical servers. This is time consuming and gives rise to the possibility of human error, particularly if the solution incorporates many DTS packages. Many companies have provided their own custom solutions for managing this problem but these are still workarounds for a problem that is inherently DTS's.
