Columns (source|object|ns) in events

[eterjack]

Good night,

Does anyone know tell me what it means to the columns in the table below events?

source, object and ns?

I need to take a table at events manually cleaned, anyone know a safe way to perform this procedure?


CREATE TABLE `events` (
`eventid` bigint(20) unsigned NOT NULL,
`source` int(11) NOT NULL DEFAULT '0',
`object` int(11) NOT NULL DEFAULT '0',
`objectid` bigint(20) unsigned NOT NULL DEFAULT '0',
`clock` int(11) NOT NULL DEFAULT '0',
`value` int(11) NOT NULL DEFAULT '0',
`acknowledged` int(11) NOT NULL DEFAULT '0',
`ns` int(11) NOT NULL DEFAULT '0',
`value_changed` int(11) NOT NULL DEFAULT '0',
)
