Structured Query Language (SQL) is the language used to manipulate data in relational databases. Learn to use SQL to select, update, insert, and delete data from database tables, and acquire hands-on experience with both Oracle and MySQL. Learn how to select data from multiple tables using joins and unions, understand how to create sub-queries to develop more complex retrieval capabilities, and use DDL to create your own database and to populate tables. In addition, learn about database design, table relationships, and normalization techniques. This course prepares you to work with any relational database, such as Oracle, DB2, SQL Server, or MySQL.
The objective of this course is to teach you the fundamentals behind the SQL language. We will discuss the concepts of databases in general, and more specifically the relational database model. We'll examine the various database engines that support this model. 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.
This course will teach you all relevant SQL concepts more from an ANSI SQL2 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 an Oracle and a MySQL point of view
The focus of the course will be on the following topics:

How to Submit Homeworks.
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.
To receive your final grade at the end of the semester,
