This page shows the details of the database structure used in ConferenceExtension. If you want to know more about how this extension works,and its architecture details then look on this page.
1. conferences edit
Fields edit
conf_id edit
This is the primary key for this table.This key would be referenced by many other tables which such as events, pages and some more.
conf_title edit
This will define the title of the conference. This value would be set by the admin during the conference setup and this is the same title which will be used as $par in the Special Page (Special:Dashboard/<conference-title>). This title will also be used for marking the title on the main page of the conference.There can't be two conferences with the same title. All the pages for the conference will have conference title prefixed in their title.
conf_begin_date edit
This is the begin date of the conference as entered by the admin. Code will use start_date and end_date to figure out the number of days for the conference.
conf_end_date edit
This is the end date of the conference.
conf_descr edit
This is the description which will be shown on the main page of the conference. And this value is also entered by the admin during the setup.
conf_venue edit
This defines the venue for the conference. Besides using it on the pages with the help of magic word such as {{VENUE}} it wont be of any use.
conf_capacity edit
This defines the upper limit for the number of attendees for the conference. Once the limit is crossed a notice would be shown on the registration page that the registration is closed for the conference. If the admin wants he/she can later change this value depending on the situation.

2. pages edit
The pages table is where we store all the information about the pages created for the conference. Each entry in this table contains a link to the core page table, this way we can keep a track of all the changes made to a page. This provides an access point for extracting pages related to a particular conference.
Fields edit
page_conf_id edit
This is a foreign key to the conferences table. As each entry of this table would be attached to one of the conferences.This column can be used to extract all the pages for a particular conference.
page_ref_id edit
This is a foreign key to the core page table(page_id). This way we can associate all the other page features already present in the Mediawiki with the new conference pages created. All the restrictions for a page, and properties for a page can be modified through this field.
page_conf_type edit
There are various types of pages that can be created for a conference such as Welcome Page, Submission Page,. All such types will be stored within a PHP array in the code, and for each type a specific code would be present. So from this array a code would be used to fill this field.
page_conf_namespace edit
This value would be the one set by the admin, and this would be same to the page_namespace(page table).

3. organizers edit
The organizers table consist of all the organizers who are set by the admin during the conference setup. There would be a separate page for displaying the organizers of the conference.
