# UR::DataSource::RDBMS::Table(3pm)

Object-oriented class for RDBMS table objects.

## NAME

UR::DataSource::Meta::RDBMS::Table - Object-oriented class for RDBMS table objects.

## SYNOPSIS

```
  $t = UR::DataSource::Meta::RDBMS::Table->get(
                      data_source => 'Namespace::DataSource::Name',
                      table_name => 'MY_TABLE_NAME');
  @c = $t->column_names;
  @f = $t->fk_constraint_names;
```

## DESCRIPTION

Objects of this class represent a table in a database.  They are  primarily used by the class updating logic in the command line tool `"ur update classes"`, but can be retrieved and used in any application. Their instances come from from the MetaDB (UR::DataSource::Meta) which is partitioned and has one physical database per Namespace.
