General description

O Deseño Software é unha fase chave dentro do ciclo de vida do software que establece a ligazón entre os requisitos dun sistema e a sua posterior implementación. O deseño máis habitual hoxe en día é o deseño baseado na orientación a obxectos, que consiste en desenvolver un programa en base a obxectos que intercambian mensaxes.

Esta materia introducirá ao alumnado nos elementos e propiedades básicas da orientación a obxectos usando unha linguaxe orientada a obxectos como Java. Aprenderase tamén a como reflectir os artefactos propios do deseño nunha linguaxe de modelado coma a Linguaxe Unificada de Modelado (UML).

Finalmente presentaranse aqueles principios básicos que representan un bo deseño e aprenderase a identificar aqueles problemas típicos de deseño e as súas solucións máis comúns representadas como patróns de deseño.

(*)The information in the planning table is for guidance only and does not take into account the heterogeneity of the students.

Methodologies

Methodologies	Description
Guest lecture / keynote speech	Lectures explaining theoretical concepts using different resources: blackboard, projection of digital slides, class notes in electronic format and other resources provided by the teachers in the Virtual Campus of the UDC.
Laboratory practice	Laboratory activities based on the knowledge that students are acquiring in lectures. Students will develop this activities preferably in groups. We will use a modeling tool to build the design artifacts and an object-oriented language (Java) to implement that artifacts.
Seminar	Seminars with activities related to knowledge acquired in lectures or laboratory activities
Objective test	Written test in which the knowledge acquired by students is assessed. Each student must apply their knowledge both in theoretical and practical level.

Personalized attention

Methodologies

Laboratory practice

Seminar

Description

Personalized attention to students includes not only tutorials (either virtual or in-person) to discuss questions, but also the following actions:

- Monitoring the work of laboratory practices proposed by the teacher.
- Evaluation of the results obtained in practice and seminars.
- Personalized meetings to answer questions about the contents of the subject.

Assessment

Methodologies	Competencies	Description	Qualification
Laboratory practice	A7 A13 A14 B1 B2 B3 B4 C3 C6	Exercises based on Java programming, object-oriented design, testing design, the modeling language UML and the use of design principles and design patterns. Plagiarized practices will be voided, both the original and the copy, and may result in a zero in the overall grade of the given assignment.	33
Seminar	A7 A13 A14 B1 B2 B3 B4 C3 C6	Seminars are practical sessions led by the teacher in which useful aspects related to the assignments are discussed. The seminars do not include the submission of assignments by the students, so it is not an evaluable activity.	0
Objective test	A7 A13 A14 B1 B3 C6	Written test conducted at the end of the semester with theoretical and practical content. It is mandatory to obtain a minimum grade of 4 in the objective test to pass the subject.	67

Assessment comments
Failure to reach the minimum score in the objective test in any of the opportunities will mean that you can not get more than a 4.5 in the final grade of the subject. Aspects to be considered for the evaluation of second opportunity (July): Laboratory practices grades are the ones obtained at the first opportunity (submission of laboratory practices in the second opportunity is not allowed). Aspects to be considered in the case of part-time enrollment: The obligation to attend activities that require to be in-person is eliminated.

Other comments
It is assumed that students know how to program and understand data structures (Programming II subject) but have never used an object-oriented language. At the beginning of the subject, as the students are introduced to the concepts of object orientation, they will become familiar with the basics of Java programming language.
