Week 4 Database Exercise Sunee Burr American Military University INFO222 Dr. Courtney Bolden December 3, 2023
Medical Records id int Last_Name varchar First_Name varchar EDIPI_id int SSN_id int Age float MilitaryStatus_id varchar Date_of_Birth_id int A) The design for this database is to assist medical facilities on base with retrieving patient information quickly by using last and first name, EDIPI, SSN, age, and military status. The design was made to be simple yet effective and time efficient for retrieving medical records. All military members, including dependents, have a unique identifier, EDIPI and SSN. Each EDIPI and SSN contain the same number making them integers. B) The first step in this table would be to input the last and first name of the patient. This will narrow your search results but is also not the recommended option, as many patients have the same first and last name. To narrow your search results, you can utilize the EDIPI, SSN and Military Status options. EDIPI and SSN are unique to each individual person. Military status will also help narrow results from active duty, reserves, and dependents. C) SSN id int SSN int Prefix int Military Status id int Active Duty varchar Reserves varchar Dependent varchar EDIPI id int EDIPI_id int Top-Down approach focuses on designing the overall architecture and them breaking the big problem into smaller ones and repeating the process. Sometimes it is difficult or impossible to break the problem down into smaller problems. Top- Down approach is commonly used during debugging. Top-Down
D) I believe that using the Bottom-Up approach to design a simple database with a small number of attributes would be best. Using this approach would benefit best because it is a smaller database with minimal entries. If the Top-Down approach was to be used, I feel there would not be many tasks to divide between all employees working on this. Since the database is supposed to be simple, it should not have to start at the highest level and work down, it should be able to be dispersed between coworkers and have them create simple issues and tasks that result in the creation of the database. Part B One-to-One A one-to-one relationship is a relationship where one record in Table A is associated with a maximum of one record in Table B. Bottom-Up approach begins with individual parts of a system being identified. They are then formed into larger components until the complete system is formed. This method solves smaller problems first to complete the solution. It has minimal redundancy, and it is used during testing processes.
