RecordsKeeper is important because It allows you to publish up to 8MB of data in key-value pair format to the public Blockchain as an immutable storage/database. It is almost impossible to create such records in centralized technologies. For uploading or publishing the data, you have to pay fees in XRK coins which get delivered to the miners. Your data is recorded onto the RecordsKeeper Blockchain as a part of transaction & which you can retrieve it any time in future for free using record key or transaction id. Data/Records uploaded in RecordsKeeper Platform are immutable & verifiable without any trusted third party.
