I decided to be generous on the sizes of the types - if computing experience shows one thing then its that it will come back to bite you in the ass if you save 2 bits in the wrong place. If performance and/or db size are too bad we can still shrink some fields.

Relationships are noted in the comment (need to double check that all are listed)

If you want more comments or if anything is confusing or bad let me know.

All money/cash amounts are stored in cents/pennies/whatever (e.g. $4.27 would be stored a 427). Chips are stored as-is (e.g. 3675 chips would be stored as 3675).

Notes on use/editing:

Any change to this must be carried to to the table creation code in fpdb_db.py or at least an entry to known bugs is to be made.

If the code (in particular the importer) and this document disagree then this document is to be considered authorative.

Table Autorates

An autorating is a computer-"recognised" label/category for a player. Examples could include "Calling Station" if a player has <20% each for aggression and folding postflop. Or "Tight-Aggressive/Aggressive" for players with <20% VPIP, >10% PFR and >40% postflop aggression.

id	bigint
handId	bigint	the site's hand number

Table HandsPlayers

cardX: can be 1 through 20, one for each card. In holdem only 1-2 of these are used, in omaha 1-4, in stud/razz 1-7, in single draw games 1-10 is used and in badugi 1-16 (4*4) is used.

For the draw games: the first 5 (badugi: 4) cards are the initial cards, the next 5 (badugi: 4) are after the first draw. If a player keeps some cards then those cards' spaces are filled with "k", short for "kept".
Example 1: If a player gets 2-6 spades for his first five cards and decides to throw away the 4 and then gets a 7 of spades then the first 10 fields of cardXValue would be as follows: 2, 3, 4, 5, 6, k, k, 7, k, k
Example 2: If a player gets 2, 3, 5, 8, J of spades for his first five cards and decides to throw away the 2 and the 3 and then gets a Q and K of spades then the first 10 fields of cardXValue would be as follows: 2, 3, 5, 8, J, Q, K, k, k, k
Note that it will k in the space of which card was there previously, so in example 2 where the player kept the last 3 cards, the last 3 fields of the first draw (ie. card8-10Value) are replaced with k.

I did not separate this into an extra table because I felt the lost space is not sufficiently large. Also the benefit for searching is far less relevant.

Table HandsActions

Did separate this into an extra table because it makes SELECTing across different streets so much easier. Also the space saving will be very large.

Field Name	Type	Comment
id	bigint
handPlayerId	bigint	references HandsPlayers.id
street	smallint	street number, 0-3 (preflop, flop, turn, river) for holdem/omaha or 0-4 for razz/stud -1 for seen showdown
actionNo	smallint	action number, this is counted from zero for each street but across all players (e.g. in a heads up where the SB calls and the BB raises and the SB calls again would have numbers 0 and 1 for blinds, 2 and 4 for call and 3 for bet) Note that the blinds are counted as an action, so if the SB stays in the hand it'll always be action #0
action	char(5)	Bet stands for bring in, complete, bet, double bet, raise and double raise, since they all - technically - do the same thing. Unbet is used for when an uncalled bet is returned, this will have a negative value for amount. Other valid values: blind call check fold
allIn	boolean	Whether the player went all-in on this action
amount	int	amount put into the middle for this action
