General description In this course, students will learn basic concepts about databases and will obtain some practical skills with two commercial DBMS, as are Oracle and Microsoft SQL Server. The student will learn: - Fundamentals about databases. - How to design a database using the Entity-Relationship Model. - How to implement a database using a Relational Model. - To use the SQL (Structured Query Language) to create databases and to query a database. - Some concepts about indexes and hash functions.

  Description
Laboratory practicals Will take place in the lab F3, using a computer in most cases for implementing and querying databases
Problem solving, classroom exercises The instructor will resolve a set of problems during the lectures, interacting with the students for answering doubts and to clarify questions.
Personal tuition Students attention will take place on person and on-line. The student will ask for an appointment using a specific agora forum prepared for this fact.
Lecture Will take place in the classroom using slides and the blackboard.

Assessment
  Description Qualification
Problem solving, classroom exercises The student will need to pass a test with two problems: a Entity-Relationship diagram and later a Relacional diagram created from a text proposed by the teacher.
To pass the course it is mandatory to pass this part obtaining at least half the maximum grade.
50%
Lecture The student will take two test to assess some of the theoretical concepts explained during the lectures:

- One test about the basic databases concepts (5% overall grade)
- Another test about indexes, concurrence and transactions (5% of overall grade)
15%
Laboratory practicals It will be a test about SQL. For passing the course it is necessary to obtain at least half of the maximum grade of this exam.
It will be necessary to submit the solutions for some practical sessions.
10%
Others All the students will carried out a practical project in groups of three.
This project will have several deliverables with fixed dates. No presentation of one deliverable will means a 20% of penalty in the final grade of the project.
25%
 
Other comments and second call

Students who do not pass a test during the continuous assessment will have another chance for every specific test in the ordinary first call.

Students who do not pass a test during the ordinary first call will have another chance for every specific test in the ordinary second call. 

To pass the course during the continuous assessment, it is necessary to pass each of the examinations of each part and also the practical project.

Students who do not present the Practical Project in the due dates will be allowed to present it in the day of the first or the second call, but they will have a penalty in their Practical Project grade. It also will be penalties for late submissions.
