Database Systems and How They are used

Database systems are utilized in basically every business every day. Businesses use data to perform a multitude of functions, such as sales transactions, customer queries, and the viewing of key performance indicators. Database systems are the management tool that aids in accessing this data. “In a sense, a database resembles a very well-organized electronic filing cabinet in which powerful software (the DBMS) helps manage the cabinet’s contents”(Rob, P., Coronel, C., & Morris, S, 2013).
Database Architecture Database Architecture refers to the design of the database. For example, databases can be designed for a single site or multiple sites, have lots of generic data or data designed for a specific purpose, or be transactional or analytical. Take Oracle database architecture for example. “Oracle9i, Oracle8i, and Oracle8 databases are powerful, flexible, and scalable relational database management system (RDBMS) servers that run on a range of computer systems, from personal computers to largest mainframes. Oracle is designed to run effectively in a client/server environment and supports hundreds to thousands of users” (Oracle, "Migration Process", 1998).
Without database systems, companies would have no means by which to access the information stored in their databases. This information is required for day-to-day operations. For instance, Craig works for Verizon FiOS selling cable, phone, and Internet door-to-door. Craig utilizes a tablet to qualify a customer’s home, verify that customer’s credit, and assign the customer an installation date. Verizon uses multiple databases and database management systems to complete these tasks. First, there is a database involving…...

...DATABASE SYSTEMS To understand what drives database design, you must understand the difference between data and information. Data are raw numbers or other findings which, by themselves, are of limited value to decision makers. Information, on the other hand, is the result of organizing, processing, and interpreting data, thus transforming the findings into facts that are useful to decision makers. For example, the number of new users your clinic serves in a month means little until you compare it with the number of new users from previous months and years to see whether there has been an increase or decrease in the trend over time. Data are transformed into information by: Selection: Choosing the data that are useful and adequate for answering the questions that have been posed, and ignoring the data that are useless or inadequate for that purpose. Interpretation: Analyzing the data to put them into context, uncover patterns or problem areas, and reflect on the meaning of these patterns in relation to the questions being asked. The overall objective of converting data to information is to describe, explain, predict, and/or evaluate a program and its results. In this “information age” production of accurate, relevant and timely information is the key to good decision making. In turn, good decision making is the key to business survival in a global market. We are now said to be entering to “knowledge age”. Data are the foundation of information which is bedrock of......

Types of Information Systems and How They Are Used Effectively

...XACC/210C The information systems that are used in the office I work at include an office information system, and a transaction processing system. Everything in my office is performed electronically. I submit all claim forms through EDI on a daily basis. EDI (electronic data interchange) is used for electronic exchange of text, graphics, audio and video. Submitting my claim forms this way creates less waste, as with the paper and mail format. It also saves money. The hardware that is used includes my computer, copy machine, and a facsimile. All of these things used make the process a lot easier. Rather than having to send and receive everything through snail mail. When submitting through an EDI, I can receive my payments back within two weeks. If I was to send through the mail, I would have to wait up to 6 weeks to receive something back from an insurance company. A transaction processing system is another information system that I use on a daily basis. I record all patient payments all with the click of a button. I also enter in patient updates and new patient data into this system. I can also remove any unwanted or unnecessary information. All transaction data is saved into this system. So at the end of the day all I have to do is print a daily payment/transaction report, and make sure I balance out at the end of the day. I suppose that this all would be included as an online transaction processing system? I feel that with the everyday use of doing......

...Problems 2,4,5,6 2. What is data redundancy, and which characteristics of the file system can lead to it? Data redundancy is a condition that exists when data environment contains redundant (unnecessarily duplicated) data and conflicting types of the data show up in other places. It can also cause information anomalies, as a change event may require multiple changes to the data. 4. What is a DBMS, and what are its functions? A database management system is a collection of programs that manages the database structure and controls access to the information stored in a database. 5. What is structural independence, and why is it important? Data characteristics that exists when changes in the database schema do not affect data access. Structural independence is important because when it is possible to make changes in the file structure without affecting the application program’s ability to access the data. 6. Explain the differences among data, information, and a database. Data are raw facts and information is the result of processing raw data to reveal meaning and stored in a database. Chapter 2 problems 13, 14, 15 13. What is a table, and what role does it play in the relational model? A table is a matrix of intersecting rows and columns. In the relational model, the table view of data makes it easy to spot and define entity relationships, thereby greatly simplifying the task of database design. 14. What is a relational diagram? Give an example. The relations......

...Hector Platon Carol Segura Fundamentals of Database Systems CS251-1303B-03 20 Aug 2013 According to Mike Chapple, Server Base Databases (Microsoft SQL, Oracle or IBM DB2) are commonly used in large organization as this type of database is able to handle sufficient amount of data simultaneously within reach of any users. This data is being updated to the server once a user resaves the file (Chapple, 2013). Server Base Database offers flexibility, powerful performance and scalability for its users which makes it a major choice for servers in most organizations. File Database (QSYS, SQLite) uses simple functions and generally uses single disk file. File Database can use several platforms. File Database can be used in 32 bit and 64 bit systems. File Database offers an excellent array of stability to its users as it functions cross platforms. Data sharing is better processed in bigger line of database management systems such as server base, wherein throughout the organization the synchronization of data is immense and constant changes is created simultaneously while File database may offer and give out cross formatting features for its clients however it can only handle minimal amount of data and is rather less reliable than the server base (Hip, 2013). My recommendation to my supervisor is to use a single database in both receiving and shipping area. The conflict begins with the shipping department that uses a Cobol program that is a stand-alone and......

...Database Systems name 3-12-2012 Web-407 Advanced Web Development instructor's name Introduction Most companies need some type of database. A company may be small or extremely large but they all share one thing in common, if they make any type of product, sell anything, keep contacts, balance the books, pretty much anything a business can any will do, they need some type of database or multiple databases to store and later retrieve the data a typical business generates. Choosing the right database is even more important in the age of the Internet, products and services can be sold around the world now and the data from shopping carts and other payment and shipping needs a database too. This article will go into a bit more detail on some of the types of databases that are available and how to pick the right one for your company. Open Source vs. Proprietary This is the big question on a lot of businesses minds these days. Rather to try and cut costs by integrating an Open Source database or a proprietary one. First off let us go over what open source means. Open source software, in this case a database, is software that generally has a limited license for free using. The software is developed and maintained by developers and coders around the world that continuously work at improving the software but providing security upgrades and bug fixes. Proprietary software on the other hand is generally developed, upgraded and patched by a company that sells or licenses the......

...Database Systems Adam Fabian DBM / 380 Database Systems Database Systems are emerging as an essential technology in today’s digital society. As human dependence on technology continues to evolve, databases continue to provide the backbone to any customer or data based system and assist organizations in storing vast amounts of information in a reference-able and organized manner. Database systems are specially designed pieces of software that store and organize vast amounts of data in a logical way that users can understand. The size of a database can range anywhere from a few simple records to millions of user accounts with detailed information and data. At my work, databases play an integral part in our company’s success. My current employer, Phoenix Diagnostic Imaging, handles thousands of records related to patient examinations conducted at our facility. The data for each patient is stored in a patient object within the database and referenced using the functionalities provided within the database application. Each one of these objects stores personal information, insurance information, examination data and images, paperwork from each visit, and referring doctor contact information. Employees use this system constantly to access patient records and insert new data into the patient records. Database architecture plays an important role in the success of a database. The three main types of database architecture are the one-tier, two-tier,......
