Project RCP: Recommerce Platform
In this project we create a recommerce platform (short RCP). A recommerce platform is a software platform that manages used media items such as books. Examples for recommerce platforms in German-speaking countries are momox or rebuy.
We start with very few requirements in the beginning. The numer of requirements will increase over time. This increase in requirements simulates demanding customers, when they get in first contact with the commissioned software project.
Keep in mind
An important aspect of software design is the anticipation of possible changing or extended requirements. We need to have this in mind while designing the basic structure of our system.
Requirements
We now know, that we create a Recommerce Platform. The RCP needs to handle information about books. On the one side, we need to be able to store information about the books we are going to sell.
On the other side this informaton must be requestable, for example from a user facing front end like a website. In addition to that it must be specified, which information describes a book. From this description our first three requirements emerge.
1) Book Meta Data
Our system must accept meta data about books. This meta data will be transmitted over network. The format of the meta data is json.
The json format looks as followed:
{
"title": "Atomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad Ones",
"author": "James Clear",
"isbn-10": "0735211299",
"quality": "very good",
"language": "english",
"publication_date": "2018/010/16",
"type": "hardcover",
"purchase_price": 2.90
}
You will find further json example files in the directory ./impl_1/json.
2) Data storage
The book meta data needs to be persistently stored by the RCP.
3) Data requests
Clients (like a website) must be able to query the book inventory over the RCP. In the first RCP version the client needs to be able to query a book by author and book title over network.
