Loading the data

There are two approaches for loading the data according to where the data is stored: file or database. First, we will take a detailed look at how to load the data from the file, including how to deal with custom formats. At the end, we quickly take a look at how to load the data from a database.

Loading data from file can be achieved with the FileDataModel class, expecting a comma-delimited file, where each line contains a userID, itemID, optional preference value, and optional timestamp in the same order, as follows:

userID,itemID[,preference[,timestamp]]
