Art Museum Database

...DMB/380 February 10th 2014 DMB/380 February 10th 2014 Art Museum Database By: For the past couple of years, a local art Museum has been collecting different art pieces from various artists. The Museum then displays the art throughout different galleries across town. The collection has significantly grown and it is now complicated for the museum to keep track of the many different artist and their different art pieces and collections, as well as where the art is located, whether it is stored in different galleries or the Museum itself. It is important for the Museum to develop a database that can keep track of the different art pieces, the artists, the different locations the pieces can be located and a total amount of pieces collected since it continues to grow at a very fast rate. The database will help the Museum substantially as well as the artists who create many various art pieces. Problems and Constraints The Museum continues to grow and it has become difficult for the manager and staff to keep track of the art collection. Not having a database that can tie the artist with his art and the location of it has caused the Museum to lose some of the different art pieces which in return equal financial losses to the Museum. Another problem the Museum continues to have is keeping track of when and where the art is being displayed. Most of the art is displayed for a period of time throughout the different galleries then either stored back...

Database Concepts

...Database Systems DBM/380 July 13, 2015 James Cervi Database Systems When it is necessary to store and manage data, a database is used. A database is a collection of data organized in such a way that it can be easily stored, managed, and manipulated. “You can think of a database as an electronic filing system” (QuinStreet Inc, 2015). It is safe to assume that a large percentage of organizations use databases for managing the wide array of data within their company. Databases can keep track of data such as: employee records, consumer demographic and contact information, and company files. A database management system (DBMS) is the software that controls the movement of data in and out of the database, as well as within the database. While a database management system refers to the software used to control the data, the database refers to the body of data being stored. Types of databases can be classified in numerous ways. They can be classified by the user, such as: desktop database meant for a single user, or a work-group database meant for multi-users. There is also an enterprise database which is used by an entire organization. Databases can be categorized by location. A centralized database manages data at a single site, whereas a distributed database manages data in multiple locations. Another way of categorizing databases is by the type of data that is being stored. “General-purpose databases contain a wide variety of data used in multiple disciplines” (Coronel,...

Database Design

...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......

Database Design

...Database Design Donavan Mitchell Database Concepts DBM/380 ALINE VOGT Database systems are structured collections of data stored in a computer system. A database must not only store large amounts of records, they also must be easy to accessed. New changes and information should be easy to input as well. Stored data that can be easily defined, like availability of equipment, cars, etc. Data that is organized to model relevant aspects of reality in a way that supports processes requiring this information Data modeling is a process used to define and analyze data requirements needed to support business processes within the scope of corresponding information in organization. It can also be thought of as a diagram or flowchart that illustrates the relationship between data. Data modeling tools and technique capture and translate complex system designs into easily understood representations of data flows and processes. Relational Model must try and develop a consistent, logical representation of information. It also provides a declarative method for queries and specifying data. Information is stated by the user and what information the database contains, gathering what they want from it. The database management system software takes care of describing data structures for storing the data and retrieval procedures for answering queries. Entity Relationship Models (ER Model) is an abstract way to describe a database. This model is the most common way to......

Database Design

...Database Design and how it is used at Wal-Mart Benjamin Stites DBM/380 7/2/2012 University of Phoenix. What is a Database System? A database system consists of four components which are the users, the database application, the database management system, and the database itself. We will describe all four components briefly. Database: The database allows a business to store important data using a collection of related tables and other structures. Database Management System: A database management system is a computer program that is used to create, process, and administer the database. (Kroenke & Auer, 2010) Database Application: A database application is a set of one or more computer programs that serves as an intermediary between the user and the database. They read and or modify database data by sending SQL statements to the database. User: The user is the fourth component of the database system. The user employs database applications to keep track of things. They use forms to read, enter, and query data, and they also produce reports. These four components allow the database system to work properly. How does Wal-Mart use its Database System? Wal-Mart is the largest retail company in the world. It needs to keep track of employee data, sales data, inventory data, profit data, and many other types of data throughout each of its stores. In order to keep up with this information Wal-Mart has outsourced its database to NCR. This allows......

...Huffman Trucking Company DBM/380 July 16, 2012 Gaya P. Agrawal Introduction During World War II it was imperative that the United States government find a way to transport products to and from different parts of the United States. Huffman Trucking Company was one of the first companies commissioned by the United States used to assist in this effort. Established in Cleveland Ohio K. Huffman started the company with one tractor-trailer and thanks to the help of the United States government, grew to 16 tractors and 36 trailers by 1945. Today, Huffman Trucking Company has 800 road tractors and 2100 45 foot trailers at its disposal. Although Huffman has been extremely successful, the need to remain competitive by use of information technology has been a challenge. It is the first company that has been recognized to outsource 100% of its information systems support. Due to the large fleet in use by Huffman Trucking through-out its many locations, the need arose for an equipment maintenance tracking system which could be accessed globally. Service Request Requirements Huffman initiated a service request for the development and design of a fleet truck maintenance database with Smith Systems Consulting. Though Smith Systems Consulting developed entities and attributes for the Fleet Truck Maintenance database, the company did not develop the database itself. According to service request SR-HT-003, the expected result of the service request is the creation of......

Statistical Databases

...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......
