Without fully grasping the idea behind the technique, a programmer is always eager to take advantage of it whenever they encounter a query performance problem, only to get disappointed by the result on many occasions. By analyzing the principle of indexing, the article tries to show programmers when is the appropriate time to use an index and how to use it.
The purpose of indexing is to quickly find…Continue

In the previous article, we discussed the necessity of the existence of a computing layer in the reporting architecture. Reporting tools support the user-defined interface-based programming with its host language (i.e. the programming language used for developing a reporting tool) to achieve the functionality of a computing layer for implementing complex computational logics, but the strategy reveals some real-life problems. An explicit data computing layer…Continue
