Consumers is someone who buys and uses products and services. Consumers also known as customers, clients, regulars, patrons and trade. Consumers have their own demand. Consumer demand led to higher imports of manufactured good. Good services must be giving to the consumer. Seller must give good services to the consumers. Bestseller need to know what is good for consumers. In this case, seller have to make an easy way to make sure the consumers do not have any problem to buy and use product and services. Currently, technology is common to everybody. Every people know how to use a technology. Design of gadgets is increase in consumers tastes. Consumer tastes also increase in a multiplication and choice in media channels and content. Technology providers are looking for innovative ways to understand consumers. Technology providers need to know their needs, preferences, tastes and desires and how these will shape the future Continue reading
Information Systems Basics
Decision Support Systems (DSS) – Meaning, Types, and Components
Decision Support Systems (DSS) help executives make better decisions by using historical and current data from internal Information Systems and external sources. By combining massive amounts of data with sophisticated analytical models and tools, and by making the system easy to use, they provide a much better source of information to use in the decision-making process. Decision Support Systems (DSS) are a class of computerized information systems that support decision-making activities. DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to successfully complete decision process tasks. While many people think of decision support systems as a specialized part of a business, most companies have actually integrated this system into their day to day operating activities. For instance, many companies constantly download and analyze sales data, budget sheets and forecasts and they update their strategy once they analyze and evaluate Continue reading
Transaction Processing Systems
The main information systems used for operational support in a business are transaction processing systems. This type of system processes data about transactions, which are events that have occurred that affect the business, such as the sale or purchase of goods. A transaction processing system has 3 main purposes: keep records about the state of an organization, process transactions that affect these records, and produce outputs that report on transactions that have occurred. For example, an inventory control system tracks records about inventory, processes sales and purchases of inventory, and produces reports about the amount and value of items on hand, on order, etc. Transaction processing systems exist in all areas of an organization, and in all types of organizations. TPSs can be used by employees (order entry) or customers (bank ATMs). They can use various types of hardware, software, and networks. TPSs use stored data in both files and Continue reading
Computer Storage Fundementals and Devices
Data and information must be stored until needed using a variety of storage methods. There are many types of storage media and devices. Computer Storage Fundamentals Data are processed and stored in a computer system through the presence or absence of electronic or magnetic signals in the computer’s circuitry or in the media it uses. This is called a “two-state” or binary representation of data, since the computer and the media can exhibit only two possible states or conditions. For example, transistors other semiconductor circuits are either in a conducting or nonconducting state. Media such as magnetic disks and tapes indicate these two states by having magnetized spots whose magnetic fields have one of two different directions, or polarities. This binary characteristic of computer circuitry and media is what makes the binary number system the basis for representing data in computers. Thus, for electronic circuits, the conducting (ON) state represents Continue reading
Data Transmission Modes in Computer Networks
Data communication circuits can be configured in a huge number of arrangements depending on the specifics of the circuit, such as how many stations are on the circuit, type of transmission facility, distance between the stations, how many users at each station and so on. Data communication circuits can however be classified as either two point or multipoint. A two-point configuration involves only two stations, whereas a multipoint configuration involves more than two stations. Regardless of configuration, each station can have one or more computers, computer terminals or workstations. A two point circuit involves the transfer of digital information from a mainframe computer and a personal computer, two mainframe computers, two personal computers or two data communication networks. A multipoint network is generally used to interconnect a single mainframe computer to many personal computers or to interconnect many personal computers. Coming to transmission modes, there are three modes of transmission Continue reading
CASE (Computer Aided Software Engineering) Tools
CASE is an acronym for computer Aided Engineering. This involves using software packages to accomplish and automate many of the activities of the information system development including software development or programming. Building Blocks Computer Aided Software Engineering can be a single tool that supports a specific Software Engineering activity to complex environment that encompasses tools, a data of people, hardware, network operating system standards and other components i.e. environment architecture composed of hardware platform and operating system support lays the ground work for CASE. But the CASE environment itself needs other building blocks. A set of portability services provides a bridge between CASE tools and their integration framework and the environment architecture. The integration framework is a collection of specialized programs that enables collection of specialized programs that enables individual’s CASE tools to communicate with one another, to create a project database and to exhibit the same look and Continue reading
