Introduction to Database Processing and Information
Database processing is one of the most important courses in the information systems curriculum. There are several reasons for this. First, databases can store large volumes of corporate operational data. Such databases become the heart of many transaction processing applications, such as order entry, inventory control, and general ledger accounting. Due to the advantages of database systems over file processing systems, many companies have converted (or are converting) their older file processing systems to database systems. Second, databases can be queried on an ad hoc basis, making them the foundation for decision-support systems (DSS). Data stored in a database can be readily accessed and processed. Consequently, users can get answers to their questions much faster if the data is stored in a database than they would if it were stored in files. Further, database query languages allow users to be more self-sufficient. Users often obtain answers to their questions without the assistance of an information systems professional. Third, databases can be implemented on computers of all sizes, making them feasible for almost any business or organization. Thus, the likelihood that you will employ database processing during your information systems or business career is almost certain. But perhaps the most fundamental reason for studying database technology is that it facilitates the production of information.
Information
The word information comes from the Latin word informare, which means “to build form” or “to give structure.” Information systems build structures from data by processing it to reveal patterns, trends, and tendencies. These patterns, trends, and so forth are the information that users need in order to perform their jobs. If we did not derive information from the huge volumes of facts we store in our computers (the data), then users would be overwhelmed with details, floundering about to find the knowledge they need. They would drown in a sea of facts. People strive to make order in their world. Think about the first time you endured the add/drop process during class registration (or the first time you went to an airport, or the first time you did anything new). If your college is like most, the room was large, hot, noisy, and chaotic. People were moving all around you and you didn’t know quite what to do. Probably your anxiety level was high as you tried to make any meaning out of the scene before you. Unconsciously, you gathered data through sight and sound, related this data to prior knowledge (such as knowing how people line up and wait their turns or take numbers and wait to be called), compared this new data to your goal (dropping a course, for example), and decided on a course of action (to get into the line marked “DROP COURSE”). The key element in this scenario is the processing of your perceptions. As you gathered data by examining the room, you built patterns and structures in your mind and tried to relate them to structures you already had. You looked for clues in people’s behavior. You might have asked somebody for help. If so, your plea was a request for information. You wanted someone who had already processed the scene and built patterns and structures to tell you what they were. As you gained information about the add/drop process, your uncertainty decreased. When you entered the room, you did not even know in which direction to turn. Once you knew which line to join, you became more sure of yourself. Information reduced your uncertainty. Computer systems provide a similar function for users. One of the main reasons for information systems is to reduce the user’s uncertainty.
What Are Portable Dental Units Or Dental Delivery Systems
A portable dental unit or delivery system is a portable, mobile unit that can become a complete, fully-functional dental office in a matter of seconds. These units help dentists practice at locations that do not have the required facilities like clean water or compressed air.
These units come with self-contained water, compressed air and vacuum systems so that the need for on-site plumbing is completely eliminated. The possibility of infections is also minimized with the use of clean water from the system. The units come with a clean water bottle and a drain water bottle. A sizeable air tank provides air for the various dental procedures. All the dental instruments are contained within a carry case that has wheels, making the whole unit extremely portable.
Some of the dental instruments found in the dental delivery system would include an ultrasonic scaler, a 3-way syringe, a saliva ejector, a 2 or 4 hole hand piece, a LED curing light, a compressor head with sufficient power, a fiber optic handpiece, an on/off foot switch, a mobile patient chair, a mobile dentist stool and an operating light.
Traveling dentists and health care personnel can use these systems at any location very effectively for a wide variety of dental procedures. The units can also be used in nursing homes and private care homes.
Apart from their use in medical facilities, these portable dental units can also be used effectively in various other locations which are far removed from proper health care facilities. Missionaries working in remote mission fields in third world countries often minister to the needs of locals that need medical attention. These portable dental units can be extremely useful in such areas for qualified health care personnel to provide medical relief to patients.
The battle field is another area in which dental delivery systems can be of tremendous use. Soldiers injured in battle can be immediately attended to using a portable unit that has the required instruments for basic medical aid.
Sometimes, vacationers in camping sites and wilderness regions might also need medical assistance during emergencies. Dental delivery systems can be of tremendous use in such circumstances.
Therefore, these portable dental units not only help dentists attend to patients within the confines of a medical facility, but also in remote regions far removed from medical care, and sometimes from civilization itself. The importance of these units can never be overemphasized as they are of vital importance in the medical field for a wide variety of medical procedures.
