This article illustrates how to issue a query on a SQL server database and save the retreived results as XML. It assumes you have a SQL Server running and the code is in C#. Summary First create an dataadapter that populates the results of a SQL query onto a dataset. Next, create an XMLWriter object that writes to a stringbuilder. Invoke the WriteXML method of the dataset to write it to the

Database Indexes are data structures that help speed up data retrieval. Similar to indexes in books, they have the same advantage - finding the reference quickly, and suffer from the same disadvantage - they take up space. App Engine has built-in indexes that can handle simple queries. Indexes for complex queries need to be generated and stored in a file called datastore-indexes.xml. Creating

In order to process images we need to get a good understanding of how to work with matrices. OpenCV has a lot of functionality for matrix manipulation. Playing around with matricesIn this article, we will see how to create, initialize and play around with matrices. Multiply two matrices and find the inverse of the resultant matrix. Assuming you have included the necessary header files (
