INFORMATION TECHNOLOGY - IT Milestone #8 Systems Design – Data Design Purpose Data is power in today's business environment. In this milestone, you will be starting the data design for New Century Wellness Group. Analysts need to be familiar with the necessary data design skills to construct the physical model of the information system. The goal with this milestone is to make you aware of how to design a relational database to be in what is referred to as normal form. Without a normalized database design, the database will be inefficient, slow, contain repeating entries, and will not provide the data needed by users to make improved decisions. You will then create an ER diagram to show the relationships among the entities which will serve as a blueprint for creating the physical database in the implementation phase. Background After completing the user interface, input, and output design for the new information system, create a normalized data design for the New Century system using standard notation format. Normalize your designs for all tables to ensure they are 3NF, and verify that all primary, secondary, and foreign keys are identified properly. Show your work from 0 Normal Formal to 3rd Normal Form. Example tables include: Insurance Company, Provider, CPT Code & Fee, Patient, Household, Payment, Claim, Appointment Service, Charge. Note: there will be additional tables once you get rid of any M:N relationships. 2. Create an initial ERD based on your standard notation for the new system that contains at least eight entities. Be sure to identify if the relationship is 1:1, 1:M, or M:N. All M:N relationships should be removed. You can use Visio to draw the ERD. Task 1) Remember standard notation starts with the name of the table, followed by parentheses that contain the field names separated by a comma. The primary key field is underlined. See the example below. Student (Student Number, First Name, Last Name, Birthdate) Task 2) No template provided. Be sure to follow the guidelines for drawing an ER diagram.

00:01 Hello student, in the given question, the purpose of it milestone, the purpose of it milestone, which is system design, systems design, the data design is to develop the data design for the new century wellness group information system.
00:34 The data design is important.
00:36 Data design is important because data is critical resource because data is critical resource, critical resource in modern business environment, in modern business environment, environment and a poorly designed database can and a poorly design design database can database can result in inefficiencies, result in inefficiencies, slow performance, slow performance, slow performance and inaccurate or incomplete data, inaccurate or incomplete data, the milestone involves designing a relational data set, the milestone involves designing a relational database, relational database that is normalized to at least that is normalized, normalized to at least 3nf, which is third normal form, meaning that, that it is free from repeating entries and boundaries, it is free from repeating, repeating entries, entries and redundancy, redundancy.
03:30 Now, the tables include, the table includes insurance, insurance company, provider, provider, cpt code and p, patients, households households, payment, payment, claim, appointment, appointment, services and charge, n is to m or m is to n, relationship should be removed to ensure proper normalization, relationship should be removed to ensure, to ensure proper normalization, proper normalization...
