Globalization can be credited for causing significant alterations in the way business is conducted and the increasingly competitive and constantly changing business environment. In many large corporations, it is not easy to detect strategic issues that confront business operations. It is also difficult to develop sustainable programs that steer organizational success. However, the advent of computers and information technology makes it easy to prepare strategic plans that facilitate the growth and success of companies. An ‘MIS’ is a strategic system that aids in collecting, analyzing, disseminating, and storing organizational data in the mode of information required to implement management functions. Management Information Systems (MIS) are concerned with planning for, development, management, and use of information technology tools to help people perform all tasks related to information processing and management. MIS aids in planning by offering the necessary information that assists in firm decision-making, especially in large organizations where the managers Continue reading

Online Analytical Processing (OLAP) – Definition, Architecture and Functionality
OLAP Council (1997) define Online Analytical Processing (OLAP) as a group of decision support system that facilitate fast, consistent and interactive access of information that has been reformulate, transformed and summarized from relational dataset mainly from data warehouse into Multi-Dimensional Databases (MDDB) which allow optimal data retrieval and for performing trend analysis. OLAP is an important concept for strategic database analysis. OLAP have the ability to analyze large amount of data for the extraction of valuable information. Analytical development can be of business, education or medical sectors. The technologies of data warehouse, OLAP, and analyzing tools support that ability. Online Analytical Processing (OLAP) enable discovering pattern and relationship contain in business activity by query tons of data from multiple database source systems at one time. Processing database information using OLAP required an OLAP server to organize and transformed and builds MDDB. MDDB are then separated by cubes for client OLAP Continue reading
What is Expert System?
An expert system is an advanced computer application that is implemented for the purpose of providing solutions to complex problems, or to clarify uncertainties through the use of non-algorithmic programs where normally human expertise will be needed. Expert systems are most common in complex problem domain and are considered as widely used alternatives in searching for solutions that requires the existence of specific human expertise. The expert system is also able to justify its provided solutions based on the knowledge and data from past users. Normally expert systems are used in making business marketing strategic decisions, analyzing the performance of real time systems, configuring computers and perform many other functions which normally would require the existence of human expertise. The difference between an expert system with a normal problem-solving system is that the latter is a system where both programs and data structures are encoded, while for expert system only Continue reading
Distributed Data Processing (DDP)
Distributed database system technology is the union of what appear to be two diametrically opposed approaches to data processing: database system and computer network technologies. Database system have taken us from a paradigm of data processing in which each application defined and maintained its own data to one in which the data is defined and administered centrally. This new orientation results in data independence , whereby the application programs are immune to changes in the logical or physical organization of the data. One of the major motivations behind the use of database systems is the desire to integration the operation data of an enterprise and to provide centralized, thus controlled access to that data. The technology of computer networks, on the other hand, promotes a mode of that work that goes against all centralization efforts. At first glance it might be difficult to understand how these two contrasting approaches can Continue reading
Case Study: Management Information System at Dell
Management information system involves the information system and the organization. MIS begins where computer science ends. Computer scientists deserve accolades for developing and delivering even more advanced forms of information technology: hardware technology; software technology; and network technology. Yet because no technology implements itself, there is more to MIS than just information technology. MIS has dimensions. The four interrelated dimensions of MIS are as follows: First, MIS involves not just information technology, but also its instantiation; second, MIS involves, as reactive and inextricable elements, both an information system and its organizational context; third, MIS involves information technology as a form of intellectual technology; and fourth, MIS involves the activities of a profession or corporate function which are integral to the essence of what MIS is. Dell Computer Corporation: Company Background Dell Computer Corporation is a major manufacturer of personal computers, computer peripherals, and software. Among the leading producers of computers Continue reading
