COURSE OBJECTIVE:

The objective of this course is to teach you the fundamentals and more advanced concepts in the SQL language. We will learn about SQL (Structured Query language) both as an ANSI standard language and more some vendor specific extensions. We will also use DDL (Data Definition Language) to create and delete database objects, and DML (Data Manipulation Language) to access and manipulate those objects.

Some of the more advanced topics covered will include database design, data normalization, SQL subqueries, creating and using views, understanding and working with the MySql and Oracle data dictionaries, loading and unloading databases. In addition, we will cover Oracle's procedural language PL/SQL, as well as MySQL procedural language

This course will teach you all relevant SQL concepts more from an ANSI SQL standard point of view. Some topics and examples however will need to be discussed with a specific database engine in mind. This course will cover SQL from both a MySql and an Oracle point of view.

The focus of the course will be on the following topics:

GRADES AND GRADING POLICY


Details of Assignment and Evaluation.

How to Submit Homeworks.

- Homework assignments are always due the next session we meet.
- Print out your homework code and output and bring with you to class the next time we meet.
- I will either collect, or will ask students to discuss their solutions in class.
- I will not accept homework via email unless you are not able to attend the class.
- Multiple pages should be stapled together (paper clips are not accepted).

Grades are FINAL.

Please do not negotiate for a better grade. If you are expecting to receive a grade of an "A" at the end of the semester, then I expect you to attend all sessions (unless I am notified ahead of time), to participate in these sessions, to keep up with the class reading material, and to complete your homework assigments. This will ensure that you stay current with the class content, and will ensure that you get a good grade on your test(s), project as well as your final grade.

If you are not interested in a grade, or you do not submit your homeworks/project or take the exams, then you will receive a grade of an "NE" (Non-Evaluative). A grade of NE is final, and cannot be changed. A grade of NE cannot be applied as partial fulfillment for any NYU certificate program.

Please Note: The Office of the University Registrar maintains individual records of students enrolled in NYU and is the only department authorized to record an official grade. Final grades are reported on NYU-Albert.
