2 Lecture 1 - overview Background to the course Content and expectations Assignments and group work Maven build system Revision control system Object-Relational Mapping

3 Prerequisites Thorough general programming background Java and Javascript Willingness to read up on technologies without detailed guidance Ability to collaborate on substantial group projects Interest in links between software engineering, platforms and organisations

4 A decade of INF5750 philosophy, socio-technical origins and evolution Information Systems Technology and organizations ICT meets social sciences history, economics, business, sociology, philosophy, anthropology Changing role of ICT => web, open source, infrastructures, platforms, social media Changing tech (eg ECMAScript 2015) Related: 5210, 5761, 5850

10 Web technology stack Client-side Javascript ES6, Angular, React Server-side Java Spring, Hibernate Storage PostgreSQL/PostGIS SQL

11 INF5750 Content Principles: e.g. ORM, Dependency Injection, Testing Common server components (a smattering of Spring, Hibernate, Node, Express) tooling: git, mvn, npm, webpack, babel, mocha, chai HTML5, Javascript, frameworks, REST web API, single-page web app dev (SPA) Platforms and open source collaboration

12 Boundary resources Software product API created Platformization New group of platform interactors

14 The course in 1 minute Version control system. Keeps versions/backups and helps you share. Build tools help you organize and build modules Hibernate maps your relational database into Java objects, and back. Spring: Configure objects & how they connect at runtime Model View Controller separates user interface, controllers and data model Javascript-enabled HTML-apps using REST-APIs on the server ( SPA )

15 Two architectures Rendering of HTML sent from server Server-generated HTML files Create HTML dynamically. Javascript parses data from server and creates HTML JSON Static HTML and APIs Javascript providing information in JSON-format.

16 Approach Lectures Knut Staring: Julie Hill Roa: Guest lecturers Lab sessions Obligatory assignments (individual) Written exam Team projects 3 devs Considerable amount of self-study First part of course and assignments focus on traditional server-side web development. Group projects focus on Javascripts-enabled

17 Evaluation Individual assignment 1 (Deadline: ca. 27th Sept) Individual assignment 2 (Deadline: ca 7th Oct) Group project work 3 milestones and group presentation late Nov Individual written exam - Early December A - F

18 Lab sessions Check the lab session schedule on Attend lab sessions. Bring your laptop!

19 Group project Develop functionality for DHIS2 A real-life open source project Objective Work with some of the most common open source components within the open source community and industry Learn to develop in teams, sharing code Learn to test and document Several groups will be working on the same project assignment

20 Individual written exam + Will cover both theoretical and practical aspects + Probably a mix of multiple-choice and essay questions relating to theory and project work

21 Learning resources Articles and books, e.g. Tiwana (2014) (full list later) Walls (2014) and other... in action books UiO guides Online documentation, tutorials and examples Beware: some may be old and not use all modern capabilities CodeAcademy, Khan Academy
