'watch glass Reports is line of descent comprehension software package for every last(predicate)owing new(prenominal) selective informationbase applications to integrate with it for designing and fetching covers for business and commercial directs. The format and the style of the insure shutting be designed on with it and it provides mechanism to be linked with several(prenominal) other types of database and front end applications. The undermentioned are the various procedures and methods for producing such reports:· normally in the form of rows and columns.· Can in like manner take the form of pie charts, bar charts and nested compendium tables.· It is as well as possible to run a crystal report without using the software itself; it is do with the help of viewers, schedulers and other report distribution tools.· It is a package with a set of ActiveX controls which keister be incorporate or embedded with several graphical exploiter interface tools to pr ovide a separate user interface (Crn.com, 2007).·  It supports data sources from databases like Oracle, MS SQL, MS Access, IBM DB2 and other applications like spreadsheets, textual matter and XML files.Actuate is another product which combines business erudition product which can combine with SQL boniface and Access. It also carries the following characteristics:·         One can develop reports for further development in future(a)·         Deployment of reports are possible·         It handles end user reporting and analytics·         It is also utilise for object designer·         The report also serves performance management and takes care of data integration. data computer storage is a concept that is employ for storing organization’s data and is unremarkably termed as corporate memory. It contains the raw significant for an enterprise’s MIS or DSS dodge. The analyst can perform complex queries which would be used for getting results and further recital of the data and the resultant information (William, 2000).The open(a) oriented feature of the data warehousing takes into account the various elements that take shoot for in the real world. It is non-volatile and integrated with consider to the data that they are never deleted and contains all the information with regard to business bear on by the enterprise for all its operations.Data excavation in contrast is filtering the data for the purpose of deriving a knowledge from it which is not possible for getting the trends of data from easy databases.It uses complex technologies for getting the punter centre of the data and its analysis. It is generally used for primarily two purposes namely knowledge breakthrough and prediction that roughly means that future prediction of events and patterns are found for getting the knowledge out of i t for business intelligence purposes (Frawley, 2001).Online processing is termed as one that is done simultaneously as the user clicks and operates online. The system responds to user behavior and makes changes to its system then for action. It promotes simplicity and efficiency for a tenableness that the user is not required to attend for any operation to take plate for general criteria.The advantages of distributed databases over centralise database can be termed as follows:·         Costs: The cost of maintaining of the distributed database at several locations are expensive with relation to technological be, labor costs and running expenses. In return the centralized database is housed in a single situation location and saves costs.·         Benefits: The benefits of distributed database would be the structured-ness, improved availability, better disruption tolerance, performance and modularity in variety and changi ng its contents. In case of centralized database, costs can be less(prenominal) but they are vulnerable to fault tolerance and availability reasons that forms good tot up of reason to switch for a distributed structure.
