As I mentioned I was not out of the subject before tacking this course, but during these lectures I discovered new topics with direct impact in my work. I liked very much the teaching style, the teacher deep knowledge of subject and the very cursive live (from memory ) presentation. The content was very easy to learn because all topics was in the right place, and very important, they was very effective explained and demonstrated. The most important thing that I liked very much was the brilliant idea to choice a self paced timing style; It was really the definitive advantage due to the condition of being hired during courses, so any time pressure could be an impediment in earning certificates. I am very glad for the opportunity to take this course, and having many other experiences in online courses I think is very appropriate the actual presentation form. During this course, my imagination was very stimulated so I developed a UML method to draw very effective theta queries (from Relational Algebra course) and to generate real SQL scripts from such a diagram. If somebody interested in the subject of UML diagramming of theta queries I could send a presentation. Thank you very much Jenifer, Your Faithfully,

This mini-course in the [Databases series](https://class.stanford.edu/courses/DB/2014/SelfPaced/about) from Stanford Online, introduces the use of the Unified Modeling Language (UML) for the creation of data models which can be translated by design tools into relational databases models for use with an RDBMS. This mini-course focuses solely on the use of UML for modelling data, and thus on the parts of UML that support data modelling. Through the use of examples the various constructs of data modelling diagrams are introduced and their specific implementations in UML illustrated. The translation of the data models created into corresponding SQL for use with a RDBMS is discussed and shown for the UML constructs which have been introduced. While the existence of UML tools which can produce SQL is mentioned, there is no mention of specific tools such as Rational Rose or ArgoUML which can perform this translation. Since UML covers many parts of the design process and the documentation of design, including aspects unrelated to data modelling, it would be better if this course had a title that reflected that it only covers the use of UML for data design.
