Read Reviews | Write Review |  Your Rating: 

Building a data warehouse involves several complicated steps (some of which I described in my previous articles for InformIT). After the data warehousing architect locates all data elements necessary to support the data warehouse, it is time to build a dimensional model.

Populating fact and dimension tables can take considerable amount of time if the population routines aren't...

Our business users want to report on some fact data aggregated by week. They define a week as beginning on Sunday and ending on Saturday without regard to the year. An example query would be how many employees were hired in each of the previous four weeks? While SQL Server has the DATEPART function which has an option to give the week number in the year for any given date, the week number resets to 1 when the year changes. Can your think of an easy way to implement this type of functionali...

Lookup tables contain, in general, a fixed list of data. This data doesn’t change very often in database business applications. Examples of this data could be a product list, category type, supplier list, state name, zip code, phone area code, etc. In Windows and Internet web business applications, most of these lookup tables are graphically implemented by using ComboBox, ListBox or CheckListBox read-only controls. These controls are loaded with data using two main columns, ID and Name. For exam...

Rather than dive into the code, these articles will demonstrate how to use these ut...

Read Reviews | Write Review |  Your Rating: 

The Stream object introduced in ActiveX Data Objects (ADO) 2.5 can be used to greatly simplify the code that needs to be written to access and modify Binary Large Object (BLOB) data in a SQL Server Database. The previous versions of ADO [ 2.0, 2.1, and 2.1 SP2 ] required careful usage of the GetChunk and AppendChunk methods of the Field Object to read and write BLOB data in fixed-size chunks from and to a BLOB column. An alternative to this method now exists with the advent of ADO 2.5. This arti...
