DBM 380 Week 1 Individual Assignment DataBase Paper

Database Systems

A database can be defined at a shared, integrated computer structure the stores a collections of end user or meta data (Coronel & Morris, 2013).  Databases are very important in every organization.  Databases can be used to track various information form employee data to monthly sales.   Depending on the size of your organization,   can determine the best way to store you data.    Microsoft Access is wonderful program that is suitable for a small work environment.  Sometimes a Excel spreadsheet can meet you data storage needs.   But larger organization needs to consider using a database management system(DBMS).  A DBMS can be defined as a collection of programs that manse the database structure and controls access to the data stored in the database   (Coronel & Morris, 2013) .

DBM 380 Week 2 Individual Assignment Database Environment Paper

Database Environment

This paper will describe a database environment within my workplace.   Currently I am in the United States Army.   We track a lot of data in the unit level for all of soldiers.  One of the most key database trackers would be tracking training data.   I chose this database because the importance of being able to track this data.   Knowing that your soldiers are fully trained is very important in making sure they can succeed on the battlefield.  This type of database would allow supervisors to check training stats, get physical training test average, and generate reports to keep track who is due or behind with training requirements.

Due to this having to be a rather large database using Microsoft Access will not be suitable.  With the amount of soldier involved you will need a DBMS (Database Management System).   This system will be a user-friendly system that will take a short training session to learn.    It will have also have shorts cuts that will generate common reports that will be needed on a daily, weekly, and monthly basis.

Huffman Fleet Truck Maintenance Database

            Huffman Trucking has asked Smith Consulting to create a UML Use Case, and Class diagram for their fleet truck maintenance database. Huffman Trucking has provided Smith Consulting with access to their existing database. By accessing the database Smith Consulting will determine what entities currently exist in the database, and the attributes of each entity. Smith Consulting will then interview Huffman employees who regularly use the database. The information gathered during the interviews will aid in the creation of a Use Case diagram.

Entities and Attributes

            Huffman’s parts catalogue is an entity of the vehicle maintenance database. The primary key of the parts catalogue is “PartID”. Each part in the parts catalogue has the following attributes:

·         Part type: regular maintenance part, or non-regular

·         Quantity On Hand: how many of the part are in inventory

·         Reorder Point: At what level of inventory is the part to be replenished

·         Reorder Quantity: How many are to be reordered at a time

·         Manufacturer: Who manufactures the part

·         Description: Description of the part and its use

DBM 380 Week 3 DQ 1

A motor vehicle maintenance center wants to improve its services by using database management systems (DBMS) and data mining. What tables are needed in such a database and how can it help improve their services?

DBM 380 Week 3 DQ 2

Huffman Trucking Change Request Four and Five

            Huffman Trucking’s network is only partially secure. The Missouri and Ohio offices are the only two portions of Huffman’s network using a firewall. The lack of separation between Huffman’s private network and the public network need to be corrected. While portions of the Huffman network are hidden behind routers, the lack of firewalls negates any protection they offer. Huffman can alleviate many of their security issues by installing proper firewalls at every Huffman location.

Access Control

            Access to the Huffman network should be attained through two part authentication. Each Huffman employee with the need to access the network should be given credentials to do so. Commonly, user names and passwords are used to dictate who can access specific portions of the network. Production staff for example will need to access inventory data, but will have no need to access accounting data. Using two part authentication and domain will allow Huffman to control which employees can access what data.

Deploying an application firewall on all of Huffman’s application servers will further secure the network.  Application fire walls will determine which application may send data over the Huffman network and to where. By using such a firewall the chances of a Huffman application being hi-jacked for malicious intent will be greatly reduced.

DBM 380 Week 5 DQ 1
