Free Poker DB Tabledesign

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.

Table HandsPlayers

cardX: can be 1 through 7, one for each card. In holdem/omaha this stores the hole cards so 3-7 or 5-7 are empty

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. Other valid values: blind call check fold
amount	int	amount put into the middle for this action
