Database model

This project’s goal was to see if the application integration can be used to compile the various types of applications together, such as legacy systems, e-business solutions, databases and ERP applications. The downside of the project was that the IT department spent 60% of total pilot implementation time on system’s design and 40% on system’s development. It took a long time as a number of systems have to be changed or phased…

quickly grown. The way law enforcement utilizes DNA evidence is by collecting a sample from a convicted criminal and storing into a database. There are two basic applications of DNA testing in law enforcement; the first involves collecting DNA samples from a crime scene and comparing them to determine if they are a match. The second application involves constructing a database of the DNA from known criminals (Tracy & Morgan, 2000). This second application would seem to only be useful if the…

better than discretionary access control (DAC)? Answer: Both mandatory access control (MAC) and discretionary access control (DAC) are important in a multiple user environment where restrictions are very important. Both are popular access control models. But they have some differences. We will find out these differences and the facts that will prove mandatory access control is better than discretionary access control. Basically, they provide access to users in different ways. A set of levels…

The rational for having Rouge One communications data centralize on a file server using a Distributed File System (DFS) is simple. When the data is centralized, instead of being spread out and existing on multiple computers will make it be easier to manage. The way this is going to be solve is a backup of the user data will be taken. This is to ensure that nothing will be lost. Then a Distributed File System (DFS) will be setup on the Rouge One communications file server. A Distributed File…

\section{Dynamic summarization of data streams} We define a data stream $X$ as a possibly infinite data set where each of the samples $x_{n}$ is available only after the time instant $t_{n}$. The arrival time of consecutive samples needs not to be equidistant; i.e., $% t_{n}-t_{n-1}$ may be different from $t_{n+1}-t_{n}$. The data available from the stream $X$ up to a given time instant $t_{n}$, $X_{n}$, is made up by the samples $X_{n}=\{x[0],x[1],x[2],...,x[i],...,x[n]\}$, where each sample…

The scrum framework is created Jeff Sutherland and Ken Schwaber in the year 1993.The word ‘Scrum’ has been derived from a paper titled “The New Product Development Game” written by the thinkers Takeuchi and Nonaka.Scrum is often compared to the team of rugby due to the analogies of small teams working for a single objective. Scrum is one of the most popular agile development methodologies and one of the easiest transitions from the waterfall approach, since it’s typically requirements-driven…

The Case of Phar-Mor Inc Read “The Case of Phar-Mor Inc.” which can be accessed through the DeVry online library. In 3-4 pages (12-pt type, double-spaced) summarize the case and answer the following questions: 1. Could SOX have prevented the Phar-Mor fraud? How? Which specific sections of SOX? The appropriate response is begging to be proven wrong because the degree that Phar-Mor went to conceal the extortion it might have taken quite a while still to reveal it notwithstanding, over the…

Task 10 (D1) Discuss how potential errors in the design and construction of a database can be avoided. One of the potential errors that can occur when creating a database is that field names and names can be spelt incorrectly due to human error this can be difficult to spot if the database is big the way of making sure that there are no naming errors is to make sure that every is checked regularly and more than twice to make sure that the chances of finding a spelling mistake is reduced. Using…

Graph consist of nodes concepts Cij and interconnections eij between concept Ci and concept Cj. A Fuzzy Cognitive Map models is a dynamic complex system it is a collection of concepts and effect relations between concepts Interconnections eij among concepts, they are characterized by a weight wij that describes the grade of causality between two concepts. Weights take…

Related Work: The problem of classifying objects in a relational database has been studied extensively within the multi-relational data mining community. There are two main approaches to deal with relational structure. The first approach is based on Inductive Logic Programming (ILP) to extend learning techniques so that they can handle relational data. On the other hand, the second approach, called Propositionalization, focuses on aggregating data in a single table so that traditional learning…
