Overview
The following section describes the key decisions and assumptions made to develop the application.
-
A room can be booked for one hour.
-
There are 20 rooms in total.
-
The rooms are pretty similar in terms of size.
-
In order to strike fairness in terms of reservation numbers, both companies will be a given a configured quota number that default to 100 reservations.
-
Both companies, to ease the reservations process, had put in charge user1 and user2 resp for COKE and PEPSI . However the system is open to put more users.
-
The available time slots to make a reservation are the following:
Timeslot |
---|
8:00 am - 09:00 am |
09:00 am - 10:00 am |
10:00 am - 11:00 am |
11:00 am - 12:00 pm |
12:00 pm - 13:00 pm |
13:00 pm - 14:00 pm |
14:00 pm - 15:00 pm |
15:00 pm - 16:00 pm |
16:00 pm - 17:00 pm |
17:00 pm - 18:00 pm |
HTTP verbs
Coladay application tries to adhere as closely as possible to standard HTTP and REST conventions in its use of HTTP verbs.
Verb | Usage |
---|---|
|
Used to retrieve a resource |
|
Used to create a new resource |
|
Used to update an existing resource, including partial updates |
|
Used to delete an existing resource |
HTTP status codes
RESTful notes tries to adhere as closely as possible to standard HTTP and REST conventions in its use of HTTP status codes.
Status code | Usage |
---|---|
|
The request completed successfully |
|
A new resource has been created successfully. The resource’s URI is available from the response’s
|
|
An update to an existing resource has been applied successfully |
|
The request was malformed. The response body will include an error providing further information |
|
The requested resource did not exist |
|
The requested resource was in conflict with an existing one. The response body will include an error providing further information. |
Hypermedia
Coladay uses hypermedia and resources include links to other resources in their
responses. Responses are in Hypertext
Application Language (HAL) format. Links can be found beneath the _links
key. Users of
the API should not create URIs themselves, instead they should use the above-described
links to navigate from resource to resource.
Resources
