Wired technology
Since year 1900, wired technology become famous because of the telephone network. Using physical wires means that electronic singles are being transmitted over a metal conductor. This is a good way to transmitting and receiving information. For purposes of this article, “wired” refers to copper wiring and does not include fiber optic technologies.
Pro's
Reliable - Not affected by other wireless signals (portable/cellular phones, microwaves, etc)
Price (wire is cheap!)
High Life Expectancy
High Speed
QoS (Quality of Service)
Con's
Affected by moisture and other weather conditions
Can be affected by noise generated by machinery and magnetics
Length of wire runs limited
Wireless Technology
Wireless technology means send information through the air, likes microwave, infrared and other to transfer data without wires between communications devices. Wireless signals were fist used in transmitting AM and FM to television and radios in the early 1950's. The military has been using "line of sight" micro-wave towers for decades. Everyone knows the most common wireless technology: cellular phones. However, this technology has several problems. The table below portrays the pros and cons of wireless technology.
Pro's
Convenient
Range
High Life Expectancy
Con's
Un-reliable - affected by other wireless signals (portable/cellular phones, microwaves, etc)
Price
Signals can be easily intercepted
Speeds are much slower than wired

The evolution of data management technology: from traditional file to data warehouse
Traditional File Processing
- Each business application was designed to use one or more specialized data files containing only specific types of data records.
- The data are organized, stored, and processed in independent files of data record
- Programs are customized to process the data.
However, there are few disadvantages of Traditional File Processing:-
1) Data redundancy
2) Lack of data integration
3) Data dependence
4) Lack of data integrity/standardization
Example of traditional file processing in a general company
The use of a traditional approach to file processing encourages each functional area in a corporation to develop specialized applications and files. Each application requires a unique data file that is likely to be a subset of the master file. These subsets of the master file lead to data redundancy and inconsistency, processing inflexibility, and wasted storage resources.
Data Management Approach
- Consolidates data into databases that can be accessed by different programs.
- Use a database management systems (DBMS)
- DBMS “is a set of computer programs that controls the creation, maintenance, and the use of the database with computer as a platform or of an organization and its end users.”
- A DBMS is a system software package that helps the use of integrated collection of data records and files known as databases.
- DBMS also allows different user application programs to easily access the same database.
- It may use any of a variety of database models, such as the network model or relational model.
- In large systems, a DBMS allows users and other software to store and retrieve data in a structured way.
Example of a database management approach in a banking system
Database management systems
Data Warehouses
- Data warehouses is a central repository for all or significant parts of the data that an enterprise's various business systems collect.
- A data warehouses is housed on an enterprise mainframe server. Data from various online transaction processing (OLTP) applications and other sources is selectively extracted and organized on the data warehouse database for use by analytical applications and user queries.
- Data warehouses emphasizes the capture of data from diverse sources for useful analysis and access, but does not generally start from the point-of-view of the end user or knowledge worker who may need access to specialized, sometimes local databases.
- Data warehouses may be divided into data marts.
- Data marts is a subsets of data that focus on specific aspects of a company (department/business process).
Phases in preparing and using a data warehouse
Components of a data warehouse
The data warehouse extracts current and historical data from multiple operational systems inside the organization. These data are combined with data from external sources and reorganized into a central database designed for management reporting and analysis. The information directory provides users with information about the data available in the warehouse.
Comparison between General Application Software and Function-specific Application Software
General purpose application software packages are generally tools that provide specific capabilities, but not in support of a specific purpose.The programs that perform common information processing jobs for end users and increases the productivity of end users, and also call as productivity packages.
Database Managers: A database contains a list of information items that are similar in format . An example is a customer phone book that lists a name, address, and phone number for each entry. Once stored in a database, information can be retrieved in several ways, using reports and queries.
Word-processing software: Word processing is the creation of documents using a word processor. It can also refer to advanced shorthand techniques, sometimes used in specialized contexts with a specially modified typewriter
Spreadsheet: A spreadsheet program is a general purpose application. It does spreadsheets, but those could be spreadsheets that you use to balance your checkbook, or manage your fantasy football league.
Function-specific application software is more accomplishes information processing task that support specific business functions or processes, scientific or engineering and other computer application in society.General purpose software can be use for more purposes but limited capabilities, but function-specific software can be used for few purposes but with greater capabilities.
SalesOutlook:Customer relationship management (CRM Software) is all about providing an affordable familiar place to organize and manage your companies most important asset: it's customers. After all, it's all about the customer. CRM combines people, technology and business processes to help automate the daily activities of your employees.

INFORMATION SYSTEMS HARDWARE: THE EVOLUTION OF COMPUTER SYSTEMS FROM MAINFRAME COMPUTER SYSTEMS TO MICROCOMPUTER SYSTEMS
Mainframe Computer Systems
Mainframe computer systems are a very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. It is also a largest data processing system employed in controlling very complex industrial processes, crunching extremely large numbers at extremely high speeds, storing massive amounts of data, generating life-like animation, processing millions of real-time transactions.
Mainframe computer systems are becoming popular computing platform for data mining, warehousing and electronic commerce applications.
Midrange Computer Systems
Midrange computer systems are high-end network servers that handle large-scale processing of business applications. Nevertheless, it is not that powerful compare to Mainframe Computer Systems. It is inexpensive to purchase, operate and maintain.
Other than that, midrange computer systems frequently used to manage large internet websites, corporate intranets and extranets, and integrated, enterprise-wide application. Besides, it can be used as front-end servers to assist mainframes with telecommunications and networks.
Microcomputer Systems
Microcomputer systems usually called a personal computer or PC. It is the most important category of computer systems for both businesspeople and consumers. The computing power has exceeded the mainframes of previous generations. Besides, PC is also comparatively inexpensive. Therefore, microcomputer systems are the networked professional workstations used by business processions.
Microcomputer systems used as the workstations to supports mathematical computer and graphics display demands such as CAD (computer-aided design), investment and portfolio analysis. In addition, it can also use as network servers which are more powerful than workstations that coordinates telecommunications and resource sharing in supporting small networks and internet or intranet websites.
