All numbers representing money is stored as the smallest unit in the current currency (ören in SEK). Thereby, many numbers have to be either divided or multiplicated with 100 to get kr in SEK.
There are three elementary entities in the system. Committees, cost centres and budget lines. Accounts are also used to link the budget to the accounting.
A committee is a project (Projekt), committee (Nämnd) or other (Annat). They are the main budget divisions. A committee contains cost centres, and the total sum of a committee is the sum of its cost centres (which is a sum of the cost centres' budget lines).
A cost centre is called resultatställe in Swedish. A cost centre is part of a committee. For example, a cost centre can be an event or a part of a committee's activity. A cost centre contains budget lines, and the total sum of a cost centre is the sum of its budget lines.
A budget line is the smallest part of a budget, belonging to a cost centre. It consists of an income and expenses and a name. If a budget line named Food has an income of 100000 and an expense of 200000, it means that someone predicts to spend 2 000 kr on food and earn 1 000 kr.
Budget lines are valid between two dates, valid_from and ``valid_to```.
