How to use FSDK.SaveTrackerMemoryToBuffer()? Luxand FaceSDK

Question

I'm making a Face Recognition DTR(Daily Time Recorder) as my Final Year Project. But my problem is the tracker is stored in a .DAT file using the FSDK.SaveTrackerMemoryToFile(). According to their documentation you can use the function FSDK.SaveTrackerMemoryToBuffer() to save the tracker on a database, but there is no tutorial on how to use that function when interacting with the databse, now what I want is to know how can I store the tracker on a database and load it whenever I want. 

Could anyone please teach me on how to use the functions FSDK.SaveTrackerMemoryToBuffer and FSDK.LoadTrackerMemoryFromBuffer in Saving ang Loading the tracker to and from the database(MySQL)?

Thank you in advance.
