Lost on electron data storage?

i have a functioning program running on the electron, I have a web site set up in a rough draft that will communicate with the electron and process the data.i have went through the azure set up and the google cloud set up… now I just am completely lost as to how to store the data so I can retrieve it as needed.if someone could recommend a tutorial or anything. I have set up the electron (asset tracker) as a gps tracking unit with speed notification. after figuring out the storage part id like to have the unit where it could lock and unlock doors, beep the horn, and turn on lights if wanted, act as if an alarm (using the accel sensor). I know the hardware side of it and the unit using the asset tracking library actually functions quite well. thank you for whoever thought out the accel sensors and made them work properly.
