What is Cognos Decision Stream? Is it an ETL tool or BI tool or DW tool?
362124
It is an ETL tool.  It is most often used by customers who have already purchased the Cognos BI tools and want to move data into information database such as data warehouses, datamarts or decision support databases.  There is some metadata sharing between the Cognos ETL and BI tools that can make implementation easier.  You could just as easily populate a Cognos BI database using any other ETL tool.

Crystal Reports is a Business Intelligence application used to design and generate reports from a wide range of data sources. Several other applications, such as Microsoft Visual Studio, bundle an OEM version of Crystal Reports as a general purpose reporting tool.\n\n\n\nCrystal Reports is one\nof the world ’s leading software packages for creating interactive reports that can be integrated into a\nwide range of Windows and Web applications.With more than four million licenses shipped,Crystal\nReports is the leader among Windows report writers.Crystal Reports has been in the Visual Studio box\nsince 1993,but with the introduction of Visual Studio .NET 2002,a new version,Crystal Reports .NET,\nwas integrated more closely than ever before.And with the release of Visual Studio .NET 2003,the bar\nhas been raised even higher,with tighter integration and more reporting options.the functionality provided with Crystal Reports.\nWhy incorporate reports into applications?Virtually all applications need to present data to users,but\nany work beyond basic formatting —charts or conditional formatting,for example —can be very com ­\nplex to program manually.provides for developers,so that you can immediately begin creating rich reports that can be integrated\ninto your Windows-and Web-based applications.

The best open-source data mining tool is definitely WEKA.\n\nIt is possible to run 50 million (1 M records x 50 attributes) attribute values in WEKA. But you have to set maximum heap size for RAM to run it.\n\nPolyanalyst is probably for user-friendly for new data miners, but if become experienced, statistical packages like MATLAB (commerical) and R (open source) are much more flexible and better.\n\nI think it is always better to use free and well-known stuff before considering paying money for commercial ones :) My bet is on WEKA if you are going to do some form of classification.

Microsoft has two ETL tools.  SQL Server 2000 and earlier has DTS - Data Transformation Services.  It is a component built into SQL Server that moves data via a Designer style palette.  Not really an ETL tool, more like a ELT tool and stored procedure code generator with some admin tasks.\n\nSQL Server 2005 has SSIS (SQL Server Integration Services), a rewrite of DTS that has a more traditional ETL client server architecture and a workflow designer for building jobs that move data.  They are built and tested within the BI development studio.\n\nThere are also a large number of ETL tools from other vendors that run on Windows and can access Microsoft SQL Server or Access databases.

COBOL isn't exactly dead. Lots of companies have millions of lines of COBOL that hums along, waiting to be replaced as soon as the search committee settles on a relational data base and a GUI interface to it.

http://en.wikipedia.org/wiki/Management_information_systems\n\nDid a search on Google and couldn't find any useful on CIS just courses\n\n"The CIS program stresses management and business legacy systems (mainframes, COBOL, RPG, and so on) plus application development for Windows environments (Visual C++ and Visual Basic, spreadsheets, etc.), primarily for large management information systems and database systems (including accounting, inventory, payroll, personnel, and sales)."

What analysis tool do you intend to use?  You talk about use-cases so it might be UML.\n\nIf so, I can suggest 2 possibilities that are different from stabndard business models:  A charitable organisation; programming a game like Monopoly.

This question is split into two sections: 1) OLAP and (2) non-relational data.\n\n1) The use of the Rubik cube method of searching for data used in applications, is split into many different types:\n\nDOLAP: PC-based tools that let users perform limited analysis of relatively small data warehouses\n\nRelational OLAP (ROLAP): Server-based tools that help technically savvy users assemble into a cube a subset of related data points that have been stored in a relational database.\n\nMultidimensional OLAP (MOLAP): Server-based tools that rely on pre-computed cubes of data to speed responses to queries.\n\nEach has their own capabilities and weakness. For new offerings, just check the multitude of programs out there, and ever growing: however, beware of what packages say they can do, and what they actually can do. Also beware of unstable programming and incompatabilities.

* 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.

Interesting question.. previously if you are a programmer.. then go for SAP ABAP, if not choose DWH coz the core concept in this is based on data analyzing. Well about Testing.. i don't know much about that.

In decision analysis, a "decision tree" ---- and a closely related model form, an influence diagram ---- is used as a visual and analytical decision support tool, where the expected values (or expected utility) of competing alternatives are calculated.\n\nIn operations research, and decision analysis specifically, a decision tree is an idea generation tool that generally refers to a graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. A decision tree is a decision support tool, used to identify the strategy most likely to reach a goal. Another use of trees is as a descriptive means for calculating conditional probabilities.\n\nIn data mining, on the other hand, a decision tree is a predictive model; that is, a mapping of observations about an item to conclusions about the item's target value. More descriptive names for such tree models are classification tree or reduction tree. In these tree structures, leaves represent classifications and branches represent conjunctions of features that lead to those classifications. The machine learning technique for inducing a decision tree from data is called decision tree learning, or (colloquially) decision trees.
