Using OneAll Social: what does the digit 1 mean in the string "user_jrOneAll: 1" ?
Using Jamroom
1 probably means 'true'. ones and zeros meaning on or off. Thats not always the case and the script developer can choose the meaning. Its a common practice just to set a marker that you can use later. So its a value used to determine how the code will function.
The reason they are called 'keys' is because of how the data is stored in the database. They are stored in a KEY=>VALUE system which is a type of database structure. What you're looking at is not formatted for any kind of informational report, its just the raw data.
