I. Introduction

1. Purpose of the requirements document

This Software Requirements Specification (SRS) identifies the requirements for Dashboard. It will specify our Single Page Application's (SPA) functionalities and the problems solved. This document will also detail our project's requirements.

2. Scope of the product

This project consists in updating a SPA. With Angular5 OAR-skylight, the precedent SPA, is not working anymore. Therefore to ease OAR's users and managers who have to use command line, the SPA has to be updated in Angular5.

This SPA will allow users to:

  • Add jobs, resources (if administrator)
  • See a listing of jobs, resources
  • Log in/Log out

3. Definitions, acronyms and abbreviations

  • SPA : Single Page Application is a web application accessed by a single web page. Its aim is to avoid loading the page at every user's actions. It interacts with the user dynamically rather than loading entire new pages from a server.
  • RESTful API : An Application Programming Interface is the defined interface through which interactions happen between applications that use its assets. REpresentational State Transfer API is a type of API that has several requirements :
    • Stateless
    • Client-Server oriented
    • Layered system
    • ...
  • OAR : OAR is a versatile resource and task manager for HPC clusters, and other computing infrastructures.
  • Angular5 : Angular5 is a TypeScript-based open-source front-end web application platform. This framework allow the user to develop one SPA for multiple desktop and mobile browsers.
