1. Scholastic Dishonesty
As commonly defined, plagiarism consists of passing off as ones own the ideas, work, writings, etc., that belong to another. In accordance with this definition, you are committing plagiarism if you copy the work of another person and turn it in as your own, even if you have the permission of the person. Plagiarism is one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which research cannot be safely communicated. If you have questions regarding plagiarism, please consult the latest issue of the Texas A&M University Student Rules [ under the section Academic Misconduct. Academic Integrity Statement “An Aggie does not lie, cheat, or steal or tolerate those who do.“ Upon accepting admission to Texas A&M University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning and to follow the philosophy and rules of the Honor System. Students will be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the Texas A&M University community from the requirements or the processes of the Honor System. For additional information please visit: On all course work, assignments, and examinations at Texas A&M University, the following Honor Pledge shall be preprinted and signed by the student: “On my honor, as an Aggie, I have neither given nor received unauthorized aid on this academic work."

5. What is a Database System?
A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects.
A database management system (DBMS) is a computer software 
application that interacts with the user, other applications, and the database itself to capture and analyze data.
