...Business Use of Databases Debra Coltey University of Phoenix Introduction to Computer Application and Systems BIS 220 April 30, 2012 Business Use of Databases Party Plates is a company that manufactures decorative paper plates and napkins. The company is undergoing so changes to the information systems that is currently used to more up-to-date technology. Some of the changes are being recommended for implantation to help ensure more accurate tracking and accounting of inventory and other information. With the improvements in technology, the more antiquated systems like Microsoft Excel can be replaced with Access Databases for more efficiency. Microsoft Access is considered to be a relational database. A relational database is a collection of data that is stored or organized in a set to tables that are predefined to certain constraints. The tables will relate to other tables within the database and the information can be reorganized in different manners ("Search Sql Server", n.d.). The data that is stored in access can be retrieved in different layouts which will help with efficiency of the company. Instead of referring to possible two or more Microsoft Excel spreadsheets to find the information required, queries in Access can be set up and modified quickly to retrieve the data needed. Access has features that are user friendly to help manage the data and retrieve user friendly reports. One feature is the radio buttons that can predefined to search within the...

...DNA databases are a compilation of DNA profiles obtained by geneticist (The Human Genome Project), medical facilities, and multiple government agencies to map and utilize the information for research and identification purposes. Most notably, the use of DNA databases are widely used within the criminal justice system to 'catch' criminals as well as exonerate the innocent. In contrast, The Human Genome Project uses the information in the database to map and understand the genes of human beings ( The human). Although the information is used in different ways, still the issue of ethics remains. Many argue that DNA is highly personal and has no place in 'databases" that are accessible to other individuals or government agencies. Some argue that these databases are no different than obtaining a fingerprint, but is 'right' because of the helpful information it brings to crime solving....

...Library Databases Search Both of the XXX Universitiy library databases and the websites were useful for searching information, but each of them was helpful in a different way. The library databases were only efficient when searched by keywords although their outputs could be controlled by using limiters to narrow down to the topics of interest. The websites, on the other hand, were useful for searching phrases and broad ideas, but their search results could not be filtered. When I first started the library search, I had no idea what to search for. Hence, I began exploring the Harvard Business School website instead. I scanned through tens of their journal articles in Research & Ideas section and spotted an interesting journal of Asian and American leadership styles (Mills, 2005). I used these keywords to search in the library databases. Surprisingly, it returned over 46,800 entries, and there were a few topics about South-East Asia. I changed the search keywords to South-East Asia Leadership Styles and "AND" Management. Then, I set other the limiters to Scholarly/Peer Reviewed Journals, Academic Journals, and 2005-to-2015. This time, the databases returned only 2,316 entries. Out of these articles, I found three academic journals relevant to my search criteria. Other topics such as Academic Transformational Leadership also appeared in the search results. I feel confident that that the library databases are an excellent resource for searching information for my research...

...Hotel Room Booking Database Evaluation I have created a booking system for the hotel which allows the user of the database, notably the hotel staff, to input all information in regards to a hotel booking, including room information and customer registration information. This is instead of the paperbased method of booking in, which the hotel uses at current. I have created the booking database as, after consideration, the hotel decided it would be a more uptodate method of booking in and after they had several issues with loss of data whilst using the paperbased method. Although it still may be the case that data is occasionally/accidentally lost while using the booking database, this is much more less likely to happen as back up copies can be made of the data, which were not made when using the paperbased method as this would be too time consuming for the hotel. I have created a database with four main parts, which are: Customer, Booking, Booking/Room and Room tables which each have a connected form. To use the Hotel Room Booking Database, the user should load the database file from the shortcut on the desktop. Then, a splash screen will be displayed this will be the first thing that the user sees when the database file is loaded. After this, the user should click anywhere on the splash screen to display the message box “Hit the OK button to progress to the login screen”. The user then clicks OK, and then OK on the following message box “You will ...

...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,...

...fundamental building blocks of modern database architecture. SQL defines the methods used to create and manipulate relational databases on all major platforms. At first glance, the language may seem intimidating and complex but it's really not all that bad. In a series of articles over the next few weeks we'll explore the inner workings of SQL together. By the time we're through, you'll have the fundamental knowledge you need to go out there and start working with databases! This week, our first article in the SQL series provides an introduction to the basic concepts behind SQL and we'll take a brief look at some of the main commands used to create and modify databases. Throughout this article, please keep our goal in mind: we're trying to get the "big picture" of SQL -- not a mastery of the individual commands. We'll provide a few examples for illustrative purposes and explain the theory behind them, but don't feel frustrated if you can't write your own SQL commands after reading this article. We'll cover each of the major commands in detail in future weekly installments. If you'd like a reminder in your e-mail inbox each week when the next article is posted, please take a moment and subscribe to our newsletter. By the way, the correct pronunciation of SQL is a contentious issue within the database community. In their SQL standard, the American National Standards Institute declared that the official pronunciation is "es queue el." However, many database professionals have taken to...

...YFOSBAPP Database A database is information organized in such a way that a computer program can quickly select pieces of data. You can think of it as an electronic filing system. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views and other objects. Data Integration Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations, which include both commercial (when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains. Data integration appears with increasing frequency as the volume and the need to share existing data explodes. It has become the focus of extensive theoretical work, and numerous open problems remain Existing DBMSs provide various functions that allow management of a database and its data which can be classified into four main functional groups: Data definition – Creation, modification and removal of definitions that define the organization of the data. Update – Insertion, modification, and deletion of the actual data. Retrieval – Providing information in a form directly usable or for further processing by other applications. The retrieved data may be made available in a form basically the same as it is stored in the database or in a new...

...407 Week 3 Database Paper In the business world, most people will find a need for a database software program to store or house data pertaining to their business. There are however, multiple things to consider before one makes their final choice on what software they will be using. A few things that should be addressed are the type of software desired, either open-source or propriety, and what characteristics of the database meets the company’s needs. There are two basic types of database programs people can choose from when deciding what they want for their small business, an open-source database or a propriety one. While both of these are similar, they still have their advantages and disadvantages. First, consider what an open-source program is. The term open-source means exactly what it sounds like; the source code for the software is completely open and free to the public. Some advantages that come with this are the fact there is no upfront costs when it comes to obtaining the database program. While this sounds great, one needs to consider the tools the business has at its disposal. If you do not have the people to manage the databases and run them, then more employees must be hired in order to support the system. This can lead to more cost in the long run. So the fact that it’s free can also be a disadvantage. Another advantage to open-source database systems is a lot of them have a huge following such as MYSQL. MYSQL is database that is designed to use Standard Query...

...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, and...

...Assignment: Databases Maurice Eugene Northam III DBM/380 January 12, 2015 Bill Enloe Databases Database Management Systems (DBMS) are mind boggling, mission-discriminating programming systems. Today's DBMS’s epitomize many years of scholastic of a, what's more, mechanical examination and exceptional corporate programming advancement. Database Management Systems were among the soonest broadly conveyed online server systems and, accordingly, have spearheaded configuration arrangements crossing not just information administration, additional system applications, working systems, and organized administrations. The early DBMS’s are among the most powerful programming systems in software engineering, and the thoughts and execution issues spearheaded for DBMS’s are broadly duplicated and reexamined. For various reasons, the least of database systems building design are not as extensively known as they ought to be. First and foremost, the connected database systems group is genuinely little. Since business compels just help a couple of contenders at the top of the line, just a modest bunch of fruitful DBMS’s usage exist. The group of individuals included in outlining and actualizing database systems is tight: numerous went to the same schools, took a shot at the same compelling exploration ventures, and worked together on the same business items. Second, scholastic treatment of database systems frequently disregards building issues. Course reading presentations of database systems...

...the Basics of Databases School University CIS 106 – Introduction to Information Technology Professor Date Understanding the Basics of Databases Databases are used to organize a collection of data, allowing for easy access, retrieval, and use of information. The first databases were slow at processing information and inconsistent when applications would require the same information, but kept in different files. Relational databases, normalization, and Structured Query Language have improved the efficiency of databases. To be a proficient database programmer, one should have a basic understanding of rational databases, normalization, Structured Query Language, and the use of database models. Relational Database The use of shared files reduced the problem with inconsistencies but was still not an efficient in accessing information. In the 1970s, a man named Ted Codd came up with the idea of the relational model for databases (Ward & Dafoulas, 2006). Similar to a spreadsheet, the relational model was based on tables, rows, and columns. Relational databases, allows the user to compare information quickly because of the logical arrangement of data in columns. The speed at which data was accessed was made possible by the development of the structured query language (SQL) query language. Because of the uniformity of relational database, completely new tables can be created from information already in existing tables. In other words, the database uses the relationship...

...Chapter 2 - Database System Concepts and Architecture Data Models, Schemas and Instances A characteristic of the database approach is that it provides a level of data abstraction, by hiding details of data storage that are not needed by most users. A data model is a collection of concepts that can be used to describe the structure of a database. The model provides the necessary means to achieve the abstraction. The structure of a database is characterized by data types, relationships, and constraints that hold for the data. Models also include a set of operations for specifying retrievals and updates. Data models are changing to include concepts to specify the behaviour of the database application. This allows designers to specify a set of user defined operations that are allowed. Categories of Data Models Data models can be categorized in multiple ways. • High level/conceptual data models – provide concepts close to the way users perceive the data. • Physical data models – provide concepts that describe the details of how data is stored in the computer. These concepts are generally meant for the specialist, and not the end user. • Representational data models – provide concepts that may be understood by the end user but not far removed from the way data is organized. Conceptual data models use concepts such as entities, attributes and relationships. • Entity – represents a real world object or concept • Attribute - represents...
