This image is a partial screen shot of the Object Browser page. It shows the right pane of the page, which includes details on the JOB_HISTORY table. Across the top of the pane are a series of links to view different types of information about the table. Below the links, running across the pane, are a series of buttons that enable you to operate on the table (for example, rename or drop it). Below the buttons is a table that describes each column in the JOB_HISTORY table. Column information includes Column name, data type, nullable, default, and whether the column participates in the primary key.
