Assignment 1: Business Rules and Data Models

A database is an incorporated PC structure that stores end-user information and metadata (Leake, A.). Data is the raw format of information, which when structured properly, it can produce accurate, relevant, and timely information that is the key to making a good database management system. The true purpose of a database is to provide computer-based systems a way in which to store, manage, and retrieve data quickly. A local college has tasked me to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants me to make the database keep track of the instructors teaching each of the courses. The local college database, will be to store the data of enrolled students, the courses offered and class schedule, and the information of the instructors. The database will provide course matches for each student based off previous courses taken and pre-requisites obtained, as well as keep track of the instructors that are teaching the class. The database will provide the data a student needs to insure they are taking the correct courses and provide the college and the faculty general student information, such as student ID. Entities (Tables) are defined as a person, place, thing, or event in which data is collected and stored. Each entity is a unique object that may be a physical or abstract object within real life (for example: Student Name) (Jones, D.). Entities of a database for a college that needs to keep track of students and courses would be students, Instructor, courses, classes, room, class schedule and enrollment status. Attributes are characteristics of an entity, such as a name, phone number, or address. Attributes(Records) for the college database would include student first and last name, student phone…...

...Bring Your Own Device (BYOD) Bikash Rasaily Deborah Blockett CIS 333 10/24/2014 Many working people appreciate Apple with its iPhone as well as blackberry for inventing the concept of BYOD also known as Bring your own device (Egan, 2013). Under BYOD concept, employees bring their own mobile devices and PCs to perform their job tasks at workplace. Many organizations that have embedded this concept in their workplace have benefit from it but we should also keep in mind about IT security of the company. Some of the key benefit of using BYOD include increased productivity and innovation, employee satisfaction and Cost saving (BYOD: Bring your own device, 2014). Employees are more comfortable with their device and are experts in using it, which makes them more productivity and innovative (BYOD: Bring your own device, 2014). They can work whenever and wherever they want and don’t have to be in their desk to do their office work. BYOD programs also help in saving money but shifting the cost to the user, with employees paying for their device and data services (BYOD: Bring your own device, 2014). Employees would be satisfied if they use the device they have chosen and invested in rather then what was selected by IT (BYOD: Bring your own device, 2014). The key way of this concept is about allowing the staff to take and use their own device is seen as employer being open-minded and flexible. The new generation prefers to work in the flexible environment where his or her......

...Assignment 1: Business rules and Data Models CIS 111: Introduction to Relational Database Management Systems Purpose of Database Spellman University had requested that I develop a database for their college. The purpose of the database will be to track the students and the courses. There also will be a place in the system to track the instructors teaching each course. There are many things to be considered in composing this database. This paper will outline the entities, attributes for each entity, the type of relationship, constraints, some business rules, and the conceptual and physical models. Entities and Attributes of Database There will be three main entities in the system; the students, the instructors and the courses. The students’ attributes would be last name, first name, social security number, and phone number, date of birth, address, student ID, level of education, enrollment date, GPA, any standardized test scored, all accepted credits, and their class schedule. The attributes for the instructors would be last name, first name, teacher ID, salary, address, telephone numbers (and or extensions), certifications, degrees, and the course code that they will be teaching. The courses attributes would be a specific course code. Along with the course code each individual class would have to have a code as well. This would make the system easier to keep track of instead of having it spelled out next to either the instructors' or the student's name. The......

She asked me if I could help her with an automated system, but has a very small budget. These days particularly in the past 10 years, even many smaller businesses have understood that computerized inventory management systems are very useful, accurate and make their jobs much easier than doing the same things manually. Inventory control is important to assure control in businesses that handle transactions revolving around consumer goods. The inventory control system must be able to warn the vendor when one of the items in the store is going to be out of stock soon and make the person who handles this kind of thing reorder (if it is a good system of course), otherwise maybe one day some important items can be out of stock, affecting the business negatively. Simply saying “we don't have that stuff right now”, is somewhat less than fully professional. The Required Equipments : Inventory management technology is a mix of hardware and software designed to add reliability to inventory accounting, reduce incidents of theft and facilitate inventory audits.

...Strayer University Week 10 Assignment 3: Business Intelligence and Data Warehouses CIS175008VA016-1154-001 Intro to Networking Professor Obi Ndubuisi June 14, 2015   For the company DesignIT, I would use a LAN type of network (for local-area network). This networks several computers, a mail (exchange) server, a database server and a file share server in one building and interconnects with each switch or backbone. I chose this for this small space because it is less than 100 square feet and is all within a single dwelling. This way the employees can all share their resources with one another, an intranet, database and printers. This network only needs a single modem with wireless capabilities and an optional access point located at the opposite end. I would recommend the wireless access-point to serve the conference room in case the client wants to set up teleconferences. We can even create an interface that when their computer finds the wireless network, a page would come up asking for their employee ID and password. This would also provide access for vendors and customers so they can have temporary access in order to have access to their files on Cloud or DropBox in order to contribute to DesignIT during their visit. Most businesses have these similar services and use ring topology or mesh topology. With ring topology there is an extra layer created, if one device fails you can pin-point the failure but the entire network would go down.  DesignIT would only......
