There are two main components that I learned at Maxwell ICT that make sure business rules can be carried out with precision and accuracy. Number 1, You need a team that will follow and implement the business rules you laid out. What good are rules if people don 't follow them? Number 2, You must find a way to establish your rules and you must make sure your rules solve a problem. There are a couple of best practice business rules that I have learned and I currently believe are essential. Number 1, always have a primary key, and if one is not given you should feel free to take the liberty to create one.

* Per the text, when databases are developed, they are modeled around business rules, so they accurately support a business function or operation.
In every business, there are laws and regulations. They control what information we can collect and share. They tell us how and what we can do with it. The automotive industry is no different, especially in the finance office. It is my desire to share this information with my team and customers. I feel it important to communicate these rules to establish clear consistent procedures. These procedures will allow us to maintain compliance, safe guard customer information, and provide ethical practices, and to provide examples of some of the industries shortcomings, and how we can move past them.
The Wikipedia article http://en.wikipedia.org/wiki/Database_design specifically mentions information gathering. It does offer some suggestions, such as cooperating with a person who is expert in the knowledge domain—a biologist, for instance, for a database storing biological data. The article “Ten Common Database Design Mistakes” http://www.simple-talk.com/sql/database-administration/ten-common-database-design-mistakes/ also notes the crucial nature of careful information gathering at the start of the process.

Business Rules: In the entity-relationship data models, business rules must take into account all relationship models: one-to-many (1:M), one-to-one (1:1) and many-to-many (M:N).

From personnel management to driving a car, laws and policies govern execution of these actions. In this paper, I will summarize a situation I encountered at work, and explain how it correlates to the content of Chapter One, (Bagley & Savage, 2010).
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.
It is very vital to implement rules, regulations and guidelines that are necessary so that individuals and organizations remain in compliance with the law. These set of polices help protect an organization from possible legal action or being penalized. It also, allows everyone to understand what is expected of them within any nature of business. Without guidelines and policies set forth by the government more than likely it would result in a breakdown in social structure, and it would result in unjust circumstances. Over the years the United States government has set many business regulations in place to safeguard consumer’s rights, protect society and hold corporations responsible for the power they have in our
