OLAP (On-Line Analytical Processing) is a technology that uses multidimensional structures to provide rapid access to data for analysis.

OLAP enables analysts, managers, and executives to gain insight into data through fast, consistent, interactive access to a wide variety of possible views of information. OLAP transforms raw data so that it reflects the real dimensionality of the enterprise as understood by the user.

Multidimensional views are inherently representative of an actual business model. Rarely is a business model limited to fewer than three dimensions. Managers typically look at financial data by scenario (for example, actual vs. budget), organization, line items, and time; and at sales data by product, geography, channel, and time.

How does OLAP organize its data?
OLAP organizes data into cubes, dimensions, and measures. A cube is a set of data that is organized and summarized into a multidimensional structure defined by a set of dimensions and measures.

A dimension is an organized hierarchy of categories (levels) that describe data in the cube. These categories typically describe a similar set of members upon which the user wants to base an analysis. (You can often recognize a dimension by the use of the word “by”—”sales by city” or “sales by year.”). For example, a geography dimension might include levels for Country, Region, State or Province, and City. A time dimension may contain the levels Year, Month, and Day.
A measure is a summation of values in the cube and is usually numeric. Measures are the central values that are aggregated and analyzed.

How does OLAP store its data?
The source data for OLAP is commonly stored in an OLAP database. An OLAP database is a database specifically structured for query and analysis. An OLAP database typically contains information that answers “who?” and “what?” questions about past events. A typical query submitted to an OLAP database is: “What was the total revenue for the eastern region in the third quarter?”

from along while i was trying to do some effort in Reporting coz

 it is very important issue for an project mostly all projects should have Reporting Module to provide the end users with statistical reports.

 i started with jasper report and  Ireport but it was booing for me.

 during R&D i found Birt (Business Intelligence and Reporting Tools) 

how to use birt?

 1-download BIRT designernow you can Design your first report the designer is easy to learn the above link provide a flash movie to show you how to build HelloWorld Report

 2-Doenload Birt runtime To Show your Report in your J2EE Application

3-delopy WebViewerExample put this folder under webApps

Now you build your first report and show the report in your j2ee Application

let’s  move to another  another important issue how to pass a parameter to the Report 

·  In your report design add a new Report Parameter ( RP_param ) ·  In your data set Query create your query with something like “WHERE ID = ?” or some other criteria using a ? for the value

. ·  In your data set add a Parameter ( DS_param ) then set the default value of this parameter to the Report Parameter you created earlier (RP_param) to do this click on the default value field then the … button

. In the resulting dialog choose Category ‘Report Parameters’, sub category ‘All’ then double click your Report Parameter to add it and click OK.
 

Al salam Alykom,

 That will be isA the first article about J2Me, just to introduce this technology.

J2ME stands for java microedition technology, it is a technology for microcomputers like PDAs, mobiles….etc.

It is mostly used in mobile applications. On using in mobile applications it needs WTK “Wireless tool kit”  instead of JDK with desktop applications, which contains the required APIs to deal with mobile applications.

That was just an overview about J2ME and it will be followed isA by more detailed and useful information about J2ME

It is very difficult to remember a set of numbers(IP address) to connect to the Internet. The Domain Naming Service(DNS) is used to overcome this problem. It maps one particular IP address to a string of characters. For example, www. mascom. com implies com is the domain name reserved for US commercial sites, moscom is the name of the company and www is the name of the

 URL stands for Uniform Resource Locator and it points to resource files on the Internet. URL has four components: http://www. address. com:80/index.html, where http – protocol name, address – IP address or host name, 80 – port number and index.html – file path.

 Every computer connected to a network has an IP address. An IP address is a number that uniquely identifies each computer on the Net. An IP address is a 32-bit number.
