Objectives, Skills and Learning Outcomes
This course aims to give the students the competences to design and develop information repositories in the Web using Object-relational database management systems and scripting languages.
After completing this course, the student will be able to:
- Elicit the requirements of an information system
- Identify the actors and their Use Cases
- Prepare Use Case Diagrams using UML
- Obtain the Domain Object Model
- Obtain the logical relational database schema
- Validate the relational schema based on functional dependencies
- Obtain the database physical schema
- Tune the logical relational schema
- Explore the database using the Object-Relational Database Management System PostgreSQL
- Write queries to the database using SQL
- Implement integrity constraints and triggers
- Define transactions
- Define an architecture for handling errors in the data accesses
- Set privileges of users and user groups
- Use the scripting language PHP and its libraries to build the user interface and business logic of the Web Application
- Obtain the user interface in XHTML
- Set presentation styles using CSS
- Validate integrity rules on data entry forms through the use of JavaScript
- Use the JavaScript library jQuery to interact with the document and to make AJAX requests
- Ensure that Web pages are obtained in accordance with the accessibility and usability standards
Program
- Development of a web application supported by a database: requirements gathering, design, modeling, implementation, testing and documentation.
- General notions of architecture of web applications using client scripting languages (JavaScript) and server languages (PHP). Models of representation of XML documents (DOM), use of Ajax framework and APIs for data access.
- Design of object-relational databases using data modeling languages (UML), the SQL language and procedural extensions to SQL.
- Identification and maintenance of business rules: on the interface (JavaScript), on the business logic and in the database (triggers); define transactions.
- General notions of usability and Web Design.

Teaching Procedures
The lectures will be used for presentation of the scripts of the work and representative examples and for their discussion, for analysis of assessments and for brief introductions to the technologies used. The practical classes will be used for laboratory project development as a group project with the teacher as a consultant.
Software
- PostgreSQL
- PHP
- jQuery Library
- Smarty Library
- PEAR-MDB2 Library
- Enterprise Architect or Dia
Evaluation Type
Distributed evaluation without final exam.
Registered Evaluation and Occupation Components
Evaluation by assessments done during the semester, according to the rules published elsewhere.

Admission to Exams
Minimum required to pass this course: 40% in each practical assignment.
Final Grade
Classification = 10% REI + 20% REBD + 20% RAP + 40% PA + 10% DI
Marks of any component of assessment may vary from element to element in the same group.
This course, given its laboratory nature is not eligible for evaluation in a single moment, so it cannot be replaced by taking an exam.
Special Assignments
There are no special works or tests.
Special Evaluation (Working Students, etc)
All students have the same evaluation.
Classification Improvement
Students may improve the mark in the subject's next edition.
