For answering this question we have to look into the definitions of data and information.\nData:-a collection of facts from which conclusions may be drawn.\nInformation-is organized data that has been arranged for better comprehension or understanding.\n          so when you talk about Data retrieval it means any sort of facts which are in raw form and not processed and when you talk about Information Retrieval it means data which are processed or data which are not in raw form and data which meet your specific requirements.\nI hope this answers your query.\n\nhttp://360.yahoo.com/darkmatter7000

In any science, complicated amounts of data make it hard to figure out what occurred to produce a specific outcome. Models are simplified explanations employed to explain a sequence of events. Models are easily shown with diagrams, and are very neat compared to the messy state in which most geologic processes result. Although they are not perfect, they can explain the reasoning geologists use in complicated situations.

good for standardizing data between different RDBMs\ngood as a medium form in converting from RDBMs to another\ngood in webpages\n\nyou cannot compare XML with the above RDBMs because XML is not a database its just a temporary data storage form

* User Interface\n    * Architecture\n    * Programming\n\nBeyond these three major areas, there are many other changes in Analysis Services 2005 (AS 2005) that are outside the scope of this article. I've listed (but not discussed) these at the end of this article. Also not covered but worth noting are enhancements to Transact-SQL in SQL Server 2005 itself which help facilitate BI analysis. For more information, you can find details on all the changes in this Microsoft whitepaper.\n\nKeep in mind that the SQL 2005 version discussed in this article is still in beta; therefore nothing should be regarded as finalized.

A graph is an illustration of the relationship between two properties of the same data points. It is also possible to have three or more properties shown on one graph for the same data. Examples would be a graph of temperature by time of day. Another graph might show temperature on one axis, date of the month on another axis, and could have rainfall on another axis. Spider graphs allow graphing many different properties on one graph. Three dimensional graphs with x,y,and z axes can also do this. \n\nTables are simply an organized list of the values of data, arranged in columns and rows, where the rows can be for unique data points, and the columns are for the properties of those data points, or vice versa. Graphs are generally used to demonstrate visually the relationships of the data in the table.

It's kind of a phased approach where one item follows another. It's general to software methodologies and not really specific to BI. There's a good diagram and some discussion in the link below.
