...Week 1: Database Paper Carmen Lozano DBM/381 John Italiano April16, 2013 When it comes to the health care database systems is a special data processing system, or part of a data processing system, which aids in the storage, manipulation, reporting, management, and control of data. When it comes to a database management system is a collection of software packages designed to store, access and manage databases. Databases are used across the health care industry to able to store patient’s files because the databases are used to store data over a long period of time. In addition it helps organizations have file access to patients file and being able to check the status or enter patients information and sure it with different organizations. When it comes to health care database systems there are four different structural types of database management systems and they are hierarchical databases, network databases, relational databases, and object-oriented databases. Hierarchical database is commonly used on the mainframe computers; this is also the oldest method being used by organizing and storing data, by organizations. This structure follows the pyramid fashion. This means that related fields are grouped together which includes higher-level records and lower-level records. When using this structure there are advantages and disadvantages that go along with this method. The advantages are files can be accessed and...

...Database Environment Paper This database environment paper contains info about a database environment for an art museum. The art museum will track artwork, artists and locations of where specific art pieces are held in the museum. An analysis of the environment will be covered, along with a description of the problems and constraints. A description of the objectives of the database environment along with the scope and boundaries are included as well. Lastly, a small list of data specifications is included. The arrangement of a collection of data is not a simple procedure. Normally, the intricacies of the data wants and the number of data methods make it difficult. As a result, arranging a collection of data is best suited to practice the traditional plan of action of separate and overcome. As a result, it should break down the arrangement method in many levels, with every transitional development is acquired that works as a beginning mark for the following phase and the final phase produces the wanted effect. In doing so, this removes the want to answer every question at one time ("Stages of Database Design", n.d.). In the case of the Denver Art Museum, a database must be created that allows users to track all the artworks, the artists who created them, and places within the museum where these works of art displayed. With an assortment of more than seventy thousand pieces of art distributed among 9 long-lasting assortments that includes western American art, African...

...Database Environment Smith Consulting is a firm that focuses building applications for their clients. One of the biggest core values within this company is to maintain the security of the data that they for which this company builds applications. ("Smith Consulting Intranet", 2015) The main focus of this company is the creation of efficient financial applications as well as other functional applications as requested. The company has about 350 employees that currently working for them across all sites ("Smith Consulting Intranet", 2015). From the company intranet there does not seem to be a current database in place for that tracks their consulting staff, clients, each staff member's skill sets, and what projects they are working on. In order to create a database we would have to first select the best database environment for the project. Within this situation the database would not house confidential information so the need for strong security would not be necessary. For this particular database the amount of data that is being imported into the database is rather small. The company has 4 main clients and 350 employees. The system that I would select for this project would be Access. Access can handle all of the data that is needed to create this Project Database. SQL and Oracle are create database structures when dealing with huge amounts of data, this would not be the case in this situation and it would not be feasible to spend the extra money on these...

...A database management system, or DBMS, is the category of computer software programs that are used in the creation, organization, retrieval, analysis, and sorting of information in computer-based databases. A database management system is comprised of: * A modeling language, which is used to define the database structure. Commonly, database structures are hierarchical, network, relational, and object based. How they go about connecting related information is where models differentiate. The relational database model is the most widely used. * A database engine, which manages the structure of the database and optimizes data storage for a balance of quick retrieval of information and an efficient usage of space. * A database query language, that allows developers to write programs that extract data from the database, present it, and allow for the saving and storage of changes. * A transaction mechanism, which validates data before storing it while also ensuring numerous users are not allowed to corrupt the data by updating the same data at the same time “Database architecture focuses on the design, development, implementation and maintenance of computer programs that store and organize information for business, agencies and institutions”. One such example is Microsoft SQL Server. There are four system databases in each instance of Microsoft SQL Server (master, model, tempdb, and msdb) and at least one user database. Some companies have a database used by...

...Database Design Paper DBM380 March 09, 2015 Database Design Paper A database is a computer structure that organizes a collection of data so that it can be accessed, updated and managed as fast and efficiently as possible. There are several classifications of databases, “For example, databases can be classified by the number of users supported, where the data are located, the type of data stored, the intended data usage, and the degree to which the data are structured. The number of users determines whether the database is classified as single-user or multiuser. A single-user database supports only one user at a time. In other words, if user A is using the database, users B and C must wait until user A is done. A single-user database that runs on a personal computer is called a desktop database. In contrast, a multiuser database supports multiple users at the same time. When the multiuser database supports a relatively small number of users (usually fewer than 50) or a specific department within an organization, it is called a workgroup database. When the database is used by the entire organization and supports many users (more than 50, usually hundreds) across many departments, the database is known as an enterprise database” (Coronel, Morris, & Rob, 2013, p. 9). Database architecture describes the rules that dictate how data is stored in a database and how data is accessed by components of a system. Database management software, such as Oracle, is designed to handle...

...International Journal of Scientific & Engineering Research Volume 3, Issue 3, March -2012 ISSN 2229-5518 1 A Distributed Transaction Model for a Multidatabase Management System Omar Baakeel and Abdulaziz Alrashidi Abstract— This paper examines the distributed transaction issues that are present in multi-database management systems (DBMSs) and how the distributed transaction in database technology differs from other distributed processing systems. Some common issues that arise with the distribution of transactions over a multi-DBMS while dealing with concurrency control and recovery are highlighted, such as site failure, network failure, and time failure. This study proposes an exceptional distributed transaction model for processing transaction queries in multi-DBMS based on the idea that a complete database can be constructed at any stage. Index Terms— Database management system (DBMS), distributed transaction, transaction management, transaction network —————————— —————————— 1 INTRODUCTION ENERALLY, a distributed transaction is defined as a transaction that updates data on two or more networked computer systems. Different conceptual structures for processing transaction elements are required to meet certain needs of applications that must update distributed data in terms of peer to peer connection. Developing a transaction model is difficult because most of these techniques are customized for a single transaction point, and many types of failures, such as client failure...

...Database Design Paper Joseph Schmosef University Of Phoenix (ecampus) DBM/380 Sunday, April 01, 2012 “A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input.” (tech-faq.com) To ensure usefulness over the long-term, databases should be built with high data integrity and the ability to recover data if the hardware fails. Information that has been corrupted or destroyed serves no purpose within a business structure. Being the Armed Forces is like being a field value in one giant database. Everything from the gear we are issued to how we are identified as an “individual” (ssn#) is a scannable number to be coded, referenced, and utilized by anyone with proper clearance. “The database architecture is the set of specifications, rule, and processes that dictate how data is stored in a database and how data is accessed by components of the system.” (wingenious.com) Database architecture type s can be broken down into three broad categories, each of which can have several subcategories: One Tier, Two Tier- client/server, and “N” Tier- client/server. The One Tier architecture is best suited to the single user and relatively small amounts of data. It runs on the user’s local machine and references a file that is stored on that machine’s...

...Database Normalization and Logical Process Concept paper This short paper will explain with a simple example the process and the need of normalization in the most of the business databases. Complete proposal break down (Timeline phases, Financial phases) will be submitted per management request. Overview At first any database should be designed with the end user in mind. Logical database design, also referred to as the logical model, is the process of arranging data into logical, organized groups of objects that can easily be maintained. The logical design of a database should reduce data repetition or go so far as to completely eliminate it. The needs of the end user should be one of the top considerations when designing a database. We should remember trough all design process that the end user is the person who ultimately uses the database. There should be ease of use through the user's front-end tool (a client program that allows a user access to a database), but this, along with optimal performance, cannot be achieved if the user's needs are not taken into consideration. Some user-related research and design considerations in any business database include the following: What data should be stored in the database? How will the user access the database? What privileges does the user require? How should the data be grouped in the database? What data is the most commonly accessed? How is all data related in the database? What measures should be taken to ensure accurate data...

...18.5/20 Database Memorandum Paper J. S CIS/319 –Computer and Information Processing 07/23/2012 Prepare a 2- to 3-page memorandum analyzing the use of databases in a business environment. Include what database applications should be used: Microsoft® Access®, IBM® DB2®, Oracle®, and so on. Conclude by proposing improvements. For large organizations, restrict the scope of the paper to the department in which you work. The use of database in the business environment has become an integral part in business processing. According to an article, Database Evolution: Microsoft Access within an Organization's Database Strategy, Chung explains that databases are used in a variety of levels for various reasons: Enterprise level, Department level, Workgroup/Team Level and Individual/small groups. With these, database systems are used as data centers in order for companies to process data, whether customer transactions, storing information (business) or to maintain security. The most popular database used today is Microsoft Office Access, or which most know it as Microsoft Access. This was developed my Microsoft Corporation and can also be used as a “frontend” with other products as the “backend” table. Which means that all the data processing can be done by Microsoft SQL Server, a Microsoft product and other database applications, for example Oracle. Microsoft Access is the main database application used by our company (Affiliated Computer Service). Due to the nature of our business...

...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...
