...Database Systems and How They are Used DBM/380 Week 1 Individual Assignment Craig Gruenbaum Instructor: Kevin Judge 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). Summary Without database systems, companies would have no means by which to access the information stored in their databases. This information...

...Database Design DBM 380 | | Databases Databases are electronic filing systems that consist of objects (Microsoft, para 2.) providing a quicker means to data retrieval than traditional paper and pen models. They have more flexibility than standard spreadsheets and offer the ability to run query searches. A properly designed database can retrieve items in complex searches; a task that might take hours or days manually, in a matter of minutes. Databases are designed to store large amounts of information without redundancy or inconsistencies (Microsoft, para 1.) Database information can be used to generate reports for specific topics, create mailing lists, manage data, share data with other programs, and perform calculations of data. Databases also can provide an area of storage for document retrieval, such as a school digital library. At work we use a complex data system known as an AS/400 system that can store and retrieve data. Database Architecture According to Georgetown University (n.d.,) database architecture is “the collective application and database instances that comprise the complete system.” This means that defined rules and specifications determine how data is stored and accessed. Web-based database architecture can use two-tier architecture or three-tier architecture depending on if the DBMS and Web server are both on the same computer (Kroenke, p. 452.) As a three-tier database architecture system the AS/400 is used to keep track of inventory...

...Database Design Larry Cohen DBM 380 James Cervi November 10, 2014 Database Design Database Systems A database is a structured group of data that is warehoused in a system. In order for a database to be functional it must be accessible and store large amounts of data. In order for databases to be reliable, in the event of a hardware failure, it must be easily recoverable. Also, the database must be flexible. Meaning, if there is something new that needs to be implemented, the database must be able to adapt to change. Database Architecture The database architecture is a set of parameters and processes that determine how data is stored and accessible by other individuals and databases. Database architecture focuses on the development, implementation, design, and maintenance of program. Design architecture helps develop software to better benefit the future user. There are numerous types of database that are created such as Oracle, SQL Server, and Microsoft Access. The SQL server is very important when it comes to database architects. Database architects use varies languages to create databases. Therefore, the languages are requested using the structured query language (SQL). IBM designed the SQL in 1974. It was first introduced by Oracle in 1979. SQL is very favorable among information technology specialist. Workplace Databases The database that my company uses is the Microsoft format. All salesman use Microsoft formatted handhelds to conduct orders and deliveries...

...Database Design Paper John Hancock DBM/380 April 23, 2013 April Johnson Database Design Paper Database systems are an organized collection of data. The data is normally organized by a couple different methods; structured and unstructured. Database systems make working in a company a lot easier when an employee is looking for information. By having a database management system in the work place the employees will have improved data sharing, data security, data access and better data integration. A couple examples of databases would be Oracle, Microsoft Access and Microsoft SQL Server. Oracle’s primary function is to store and retrieve data as it is requested. Database architecture not only focuses on the design, development, implementation and maintenance of computer programs that store and organize database information for any business or company big or small. Also a database architect my use a vast array of different languages to create a database, one language is called the structured query language or SQL. When I was in the Navy at first I didn’t realize how structured all of the information was and how much information was actually kept on file. Every duty station has a database system that is used which is Oracle. This database in particular is a very great database for the Navy to use because as information is needed a service member can access the information on the Oracle database cloud at any given time. Also the service member will know that the information...

...base Database Design Paper DBM 380 A database system arrange information in a computer, enforced by a set of computer programs. An organization of this kind should offer simplicity an easy way to access connect, display and collect information. A database management system allows users the capability to enter data within the database by the use software. This software is designed to manipulate, define, retrieve and manage data in the database. One tier architecture type of database would be Microsoft Access. A desktop computer is an example of what Microsoft Access uses to run a list personal phone numbers and addresses that has been saved in MS Windows “My Document” folders. A tier two architecture database application would be Oracle or SQL server. Also, communication is accomplished through a Microsoft Windows server and are GUI based. The choice of preference used in my workplace is One Tier. Management has access to Microsoft Office, Excel, and Access. Additionally, there are several different databases that are password protected through a web based GUI to get important information about different Dell systems and Dell troubleshooting steps to repair hardware and software issues. To log customer information and other Dell tools the company use Citrix servers that workstations connect with to edit and retrieve data. Because of the large amount of individuals editing information on...

...Database Design Paper Amanda Chavez DBM/380 February 16, 2015 Pamela Hurd It is important for a business to keep track of certain data. Data management works best if the business has a computer database. A database is a computer structure that stores end-user data and metadata. A database allows data to be saved, managed and retrieved whenever data is needed. It is essential for businesses to save all of their data, such as products they are selling, because this type of data can become useful when there is a decision to be made. Businesses can use the data as a source. Businesses use databases as a way to store their data. They are able to retrieve the data whenever they need it. Modern businesses depend heavily on databases. Databases store a business’ valuable data. A business’ database can hold email addresses, phone numbers, and names which can help the business sell more of their products and/or services. Databases are also used to provide information to the general public. For example, long ago we used the Yellow Pages to look up a person’s contact information. Nowadays, the YP book is still made but they also have the website, which is more modern for today. Database architecture uses programming languages to design, develop, implement and maintain a certain type of software that allows businesses to store information. The goal is to meet the needs of users. Oracle is an example of database architecture. Oracle Database is the first database created for “enterprise...

...Database Environment DBM/380 The Historic Art Museum of Buffalo, NY needs to keep track of an abundance of information. Such as the artwork, artists, and locations of where the art is displayed or stored within the museum. Unfortunately, the museum is currently using only a Microsoft Office Excel spreadsheet to keep track of the artists, artwork, and their locations. This is not good practice and generally causes hardships for end-users. Therefore, a database will be implemented in order to make the information more readily available and accurate. Objectives of the Database First and foremost, is the objective of the database system - which is to store the following information: which art is owned/possessed, which artists, and the location of the art within the museum. By having this information readily available in a managed database, it can help the museum prepare for showings, buy/sell/trade/acquire artwork, and maintain an accurate inventory. The Database’ Environment The database’ environment shall consist of metadata & data, software, hardware, people to operate the equipment, and the appropriate procedures for the individuals to follow. Within the museum, the following devices (iMac 21.5 inch model) will be used as workstations by employees and networked together in order to access the server of which the database will be stored. The iMac devices are expensive, but have the capability of running Boot Camp for employees that desire to use Windows. And...

...Statistical Databases Jaideep Srivastava and Hung Q. Ngo, Department of Computer Science, University of Minnesota, 200 Union street, EE/CS Building, room 4-192, Minneapolis, MN 55455 e-mail: srivasta, hngo @cs.umn.edu, ¡ 1 Introduction A statistical database management system (SDBMS) is a database management system that can model, store and manipulate data in a manner well suited to the needs of users who want to perform statistical analyses on the data. Statistical databases have some special characteristics and requirements that are not supported by existing commercial database management systems. For example, while basic aggregation operations like SUM and AVG are part of SQL, there is no support for other commonly used operations like variance and co-variance. Such computations, as well as more advanced ones like regression and principal component analysis, are usually performed using statistical packages and libraries, such as SAS [1] and SPSS [2]. From the end user’s perspective, whether the statistical calculations are being performed in the database or in a statistical package can be quite transparent, especially from a functionality viewpoint. However, once the datasets to be analyzed grow beyond a certain size, the statistical package approach becomes infeasible, either due to its inability to handle large volumes of data, or the unacceptable computation times which make interactive analysis impossible. With the increasing sophistication of data collection instrumentation...
