The term OLAP (On-Line Analytical Processing) was coined by E.F. Codd in 1993 to refer a type of application that allows a user to interactively analyze data. An OLAP system is often contrasted to an OLTP (On-Line Transaction Processing) system that focuses on processing transactions such as orders, invoices or general ledger transactions. OLAP is now acknowledged as a key technology for successful management in the 90’s. It describes a class of applications that require multidimensional analysis of business data. OLAP systems enable managers and analysts to rapidly and easily examine key performance data and perform powerful comparison and trend analyses, even on very large data volumes. They can be used in a wide variety of business areas, including sales and marketing analysis, financial reporting, quality tracking, profitability analysis, manpower and pricing applications and many others. OLAP technology is being used in an increasingly wide range of applications. The most co...

The realization that stand - alone computers made no sense made the network possible. When there were too many of them, people realized that stand - alone networks made little sense either, and that they also needed to talk to one another. This was the problem confronting the US Government and the academic community in the late 60s. Everything they had was heterogeneous-computers, networks, operating systems and networking software. Connecting these networks was either impossible or done using expensive proprietary network devices. Something had to be done. Rather than surrender to the monopoly of vendors, the US Department of Defence (DOD) initiated work on a project with a simple objective: develop a set of standard rules (Protocols) which could be used by all machines and networks to communicate. The solution had to be vendor - neutral, independent of the hardware or the operating system, and even the geographical location. The solution they found was TCP/IP/. It became so...

The network infrastructure is the underlying foundation of the system. It forms the services that create the operating makeup of your network. In a Communications Services deployment, determining your network infrastructure from the project goals ensures that you will have an architecture that can scale and grow. The Existing Network We need to understand our existing network infrastructure to determine how well it can meet the needs of our deployment goals. By examining our existing infrastructure, we identify if we need to upgrade existing network components or purchase new network components. We should build up a complete map of the existing network by covering these areas: Physical communication links, such as cable length, grade, and so forth Communication links, such as analog, ISDN, VPN, T3, and so forth, and available bandwidth and latency between sites Server information, including: Host names IP addresses Domain Name System (DNS) server for domain membership ...

The primary concept of data warehousing is that the data stored for business analysis can most effectively be accessed by separating it from the data in the operational systems. A data warehouse is a collection of computer-based information that is critical to successful execution of enterprise initiatives. A data warehouse is more than an archive for corporate data and more than a new way of accessing corporate data. A data warehouse is a subject-oriented repository designed with enterprise-wide access in mind. It provides tools to satisfy the information needs of the employees organizational levels-not just for complex data queries, but as general facility for getting quick, accurate and often insightfulinformation. A data warehouse is designed so that its users can recognize the information they want and access that information using simple tools. One of the principal reasons for developing a data warehouse is to integrate operational data from various sources into a single and...
