Introduction

In this course you will learn in more detail how the communication between clients and servers on the web works, i.e. learn the HTTP protocol. This will then be used to create a "web application" not only web browsers can communicate with, but any type of application connected to the Internet can communicate with using a REST API. This is convenient for smartphone applications and similar when they need to be able to store data from the users in the cloud instead of locally on the smartphone device.

below displays an overview of how it can work.
Common web application architecture.

At course start you are expected to possess knowledge corresponding to the pre-requisite courses shown in below.

Prerequisites for this course.

Learning Activities

Here are short introduction to the learning activities offered in the course.

Recorded Lectures

In the beginning of most weeks you will be encouraged to view some recorded lectures. These will be quite theoretical and will teach new you things you can use when building a platform.

Tutorials

Most weeks there will be a tutorial session where the teacher will show you how to use what has been taught in the recorded lectures in practice.

Lab Sessions

Each week you may attend a 4 hours long lab session. At the lab session you may ask the teacher there for help with your lab and project work.

There are 2 different lab sessions each week, but you may only sign up for one of them. To distribute you, join one of the Lab Groups on Canvasopen in new window. First come, first served.

Attending more lab sessions

You may attend the other lab session if there is room for it, but the teacher there must of course prioritize helping the students that have signed up for that lab session.

Examination Tests

The course contains two examination tests.

1. Laboratory Work

1 credit, graded fail/pass. More information is available on the Laboratory Work page.

2. Project Work

4.5 credits, graded U, 3, 4 and 5. More information is available on the Project Work page.

3. Written Examination

2 credits, graded U, 3, 4, and 5. More information is available on the Written Examination page.

Final Grade

To receive a final grade on the course you need to pass all examination tests (Laboratory Work, Project Work and Written Examination). The final grade will be based on the lowest grade of the Project Work and Written Examination , but these grades will also be marked as weak or strong. If one of the grades is lower than the other and has been marked as strong, the final grade will be the lower grade + 1. Examples:

  • A strong 3 and a weak 4 gives you 4 as the final grade
  • A weak 3 and a strong 5 gives you 3 as the final grade

For Written Examination, 50% of max score is a strong 3, and 70% of max score is a strong 4.

Re-examination

below shows the study and exam periods during a year. The small blue circle sectors shows when the (re-)examinations are offered in this course.
Study periods and re-exam periods in an academic year. Big circular sectors are study periods, small circular sectors are (re-)exam periods. Blue circle sectors are part of period 1. Green circle sectors are part of period 2. Yellow circle sectors are part of period 3. Red circle sectors are part of period 4.

Re-examination for all examination tests will be offered at the re-exam periods in January and August. To learn precise dates before they have been announced, email the course coordinator at peter.larsson-green@ju.se. The project work will only be graded U/3 at re-examination.

Last time the course run!

This course is this year running for the last time. Therefor, you will have 2 more re-examination opportunities in addition to the ones described above. More information about these will be announced later. To learn more, email the course coordinator at peter.larsson-green@ju.se.

If you haven't passed the course after the ordinary examination opportunity + the 4 re-examination opportunities, you can't pass the course. If this happen to you, contact your student councilor or program manager to learn your alternatives.
