sql - Correctly Modeling Sports Statistics in a Relational Database -

-

I am trying to model football figures in postgresql and do something like that, but it feels right does not do. Here's the problem:

I have team, sports and statistics. There are two teams for each game. There is an aggressive figure line in each team that can run, run, and so on. However, this aggressive situation is based on the defensive statistics of the other team, e.g. If the offensive team has a distance of 100 yards in the game against the defense team, then the rescue team has run away running 100 yards and it is important to track both these offensive and defensive statistics.

FootballTam, FootballGam, FootballStat and FootballTamstate, as a linking table between football and football, is a foreign key to footballgam in FootballStat. FootballTamstats have two foreign keys, one for FootballTam and one FootballStat. It also has a StatTypeId, which is a flag for any offensive or defensive. By doing so, I can avoid a lot of flaws in Footballstate, where I will have two rows for the same state, but an aggressive flag and a defensive flag.

It works very well in my current application, but it has never felt completely right. Is there a better way to do this? My database modeling experience is limited to projects in a great amount, which I have done after reading the database design for my deaths and when it adheres to my most experience, I'm not sure that this is the best way.

> Edit: Updated to make it normal rather than league specific.

You are on the right track, I only recommend giving tables a little better name: FootballSTAT and FootballTamst Read in the form of figures that were in existence with and without any team reference. ul:

IE: DEF: defensive, off: offensive

team-statistics-type-code

  • Description

IE: 1, for example, OFF, rushing

Team

  • Team-ID (PK)

Team-Statistics

  • Game-ID
  • Team-Statistics-Type-Code-ID (FK: Team-statistics-type
  • VALUE:

    • IE: 1, 1, 1, 100

    I know that offensive and defensive figures are important , But if any state will always remain aggressive and defensively - you can only get away with invasive data entering & amp; Using SQL to calculate defensive people IE: If dealing with 100 yards error is a defensive loss of 100 yards, do you benefit from the storage of protective information or should you make mapping in DB so that you can query Can I get SQL to reverse the values ​​through or see?

    c# - ListView onScroll event -

    -
    I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

    Linux Terminal Problem with Non-Canonical Terminal I/O app -

    -
    I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
