...University of Phoenix Material Determining Databases and Data Communications Read Scenario 1 and Scenario 2 below. Write a paper of no more than 1,500 words in which you respond to the questions designated for both scenarios. Scenario 1: You are a marketing assistant for a consumer electronics company and are in charge of setting up your company’s booth at trade shows. Weeks before a show, you meet with the marketing managers and determine what displays and equipment they want to display. Then, you identify each of the components that need to be shipped and schedule a shipper to deliver them to the trade show site. You then supervise trade show personnel as they set up the booths and equipment. After the show, you supervise packing the booth and all the equipment as well as schedule its shipment back to your home office. When the equipment arrives, you check it into your warehouse to ensure that all pieces of the booth and all the equipment are returned. If there are any problems due to shipping damage or loss, you handle those problems. Your job is important; at a typical show you are responsible for more than a quarter-million dollars of equipment. • In Scenario 1: o You need to track data about booth components, equipment, shippers, and shipment. List typical fields for each type of data. Provide an example of two relationships that you need to track. o Do you need a database system? If not, can Excel® handle the data and the output? What...

...or the programs in such a way that they become in machine readable form. Once the system is done with the coding stage it tests the systems and sees to it that it is working as per the expectations or not. System implantation is one of the most vital phases as in this phase the analyst actually gives the system to the customer and expects for a positive feedback. Finally, the system maintenance is that the analyst needs to maintain the system and see to it that it working within the standards set. He needs to maintain the system by removing the defects of flaws occurred. I think this relates to database development because in 1960 the developers, Elliott and Strachan and Radford developed large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines. The database is also a design lie...

...IST 792 paper 2 Database security is a growing concern evidenced by an increase in the number of reported incidencets of loss of unauthorized exposure to sensitive data. As the amount of data collected, retained, and shared electronically expands, so does the need to understand database security. (Murray, 2010) Database security concerns the use of a broad range of information security controls to protect databases (potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links) against compromises of their confidentiality, integrity and availability. It involves various types or categories of controls, such as technical, procedural/administrative and physical. Database security is a specialist topic within the broader realms of computer security,information security and risk management. Security risks to database systems include, for example: * Unauthorized or unintended activity or misuse by authorized database users, database administrators, or network/systems managers, or by unauthorized users or hackers (e.g. inappropriate access to sensitive data, metadata or functions within databases, or inappropriate changes to the database programs, structures or security configurations); * Malware infections causing incidents such as unauthorized access, leakage or disclosure of personal or proprietary data, deletion of or damage to the data or programs, interruption or denial of...

...The Getty Provenance Institute’s database (The Gettys research institute, 2012) contains 1.1 million records. All of these records can be used for a wide variety of research. According to the institute the database can be used for assistance in finding information for Projects, and for the Study of Collecting. According to the Database, “The J. Paul Getty Museum acquired The Entombment (ca. 1612) by Peter Paul Rubens in a Christie's sale in 1992. At that time, the provenance of the painting could only be traced as far back as the mid-19th century. The number 146, located on the face of the painting, appeared to be an inventory number (the Getty Research Institute, 2012). A search in the Provenance Index's Archival Inventories database retrieved a single record in which the artist name (Rubens) and item number (146) matched. The search lead to a 1651 inventory preserved in the Archivo de la Casa de Alba, Palacio de Liria in Madrid, which lists this Rubens painting. Possibly its first owner was Gaspar de Haro y Guzmán Carpio (1629–1687)”. Other Institutions are not as lucky some. Some Museums are not so fortunate to find the item number associated with the picture. When it is time to introduce the collections into a database, curators of small museums find themselves in a little bit of trouble. The features and capabilities offered by the newer commercial and professional collection systems are more than they will ever need, more than they can support and more than they...

...New Database Program for ACCC Michele Ritchie SCI110 – Introduction to Physical Science Instructor Casey Bethel February 17, 2016 The Scientific Method The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The steps of the scientific method are to ask a question, do background research, construct a hypothesis, test your hypothesis by doing an experiment, analyze your data and draw a conclusion, and communicate your results. Problem Statement At American Classic Carpet Care, a nationwide commercial and retail carpet cleaner, we have several different databases that we use for our client base. Each database contains a certain type of business contact. For example, one database is for hotels only, another is for restaurants only. Then, we also have separate databases for local work and out of state work. As you can see, one restaurant or hotel could potentially be put in more than one database. Currently, we use the Pro 2011 version of ACT!. This version is not set up to transfer information from one database to the other automatically. Manually transferring information one client at a time is very time consuming. Overview of Alternatives Alternative #1- Upgrade to ACT!

...INSY 5337 Data Warehousing – Term Paper NoSQL Databases: An Introduction and Comparison between Dynamo, MongoDB and Cassandra Authored ByNitin Shewale Aditya Kashyap Akshay Vadnere Vivek Adithya Aditya Trilok Abstract Data volumes have been growing exponentially in recent years, this increase in data across all the business domains have played a significant part in the analysis and structuring of data. NoSQL databases are becoming popular as more organizations consider it as a feasible option because of its schema-less structure along with its capability of handling BIG Data. In this paper, we talk about various types of NoSQL databases based on implementation perspective like key store, columnar and document oriented. This research paper covers the consolidated applied interpretation of NoSQL system, depending on the various database features like security, concurrency control, partitioning, replication, Read/Write implementation. We also would draw out comparisons among the popular products and recommend a particular NoSQL solution on the above mentioned factors. 1. Introduction Until recently, Relational database systems have been on the forefront of data storage and management operations. The advent of mobile applications that requires real time analysis like GPS based services, banking and social media has led to huge unstructured data being produced every second. Traditional RDBMS systems have found it difficult to cater to these huge chunks of unstructured...
