Summary0000475: Improvements on some tables
DescriptionTable user:

We should have an issuer table with a list of our roots, and only the root_id on the user table. This allows for future expansion, and for third-party use. Remember CAcert is going to release its code as open-source.

  `root` set('CA Cert Signing Authority','CAcert Class 3 Root') collate latin1_general_ci NOT NULL default '',
should be changed with a foreign relation to the issuer table.

LANG doesn't always come in 2-letter flavours, for example "pt_BR.ISO8859-1". We are kinda breaking ISO here, which is a bad idea :)
  `lang` char(2) collate latin1_general_ci NOT NULL default '',

Database encoding should be changed to UTF-8 to allow non-ascii-writing people to use the system. Think asia!

Table topics:

numOfQu shouldn't exist like that. we should count() questions for that topic instead. Desyncs are bad!


Table learnprogress:

root -> see table user comments
percentage as decimal(5,0): I wonder who can do 99999.00% of it right ;) decimal with 0 decimal positions is a misuse -> try int ;)



All Tables:

We should use BOOL (BOOLEAN) type instead of enum, to avoid the conversion overhead.

MySQL 5 Reference:
"BOOL, BOOLEAN

These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true: "
TagsNo tags attached.

Bug 0000472 comment 982 reminded me to comment about "Not Null" statements that should be on all collumns on all tables unless there REALLY is a meaning for that collumn being null.

Bug 0000465 suggests the lack of unique constraints/indexes needed to eliminate problems with duplicate records automatically

numOfQu doesn't count the questions of a topic.
Here is stored how many questions a test of this topic has.
p.e.
Topic 1 : numOfQu=5
Topic1 has 5 questions per test.

Maybe it is named unfortunately.
I think we should rename it.

RFC 3046 (http://tools.ietf.org/html/rfc4646#section-4.3) recommends a buffer length of at least 42 characters for language tags.
Since I don't think that this will lead us into storage problem we should adher to this (though I doubt we'll really use even 10 characters).
