    <p>The official standard is <a href="http://en.wikipedia.org/wiki/ISO/IEC_11179" rel="nofollow noreferrer">ISO/IEC 11179</a> ... which will make your head hurt and refers to semantic elements of the documented data-model when we usually need both semantic and physical (tables, fields etc.) documentation in a 'real world' data dictionary.</p> <p>Personally, I favour (however you implement this is up to you) physical and optionally logical Entity-Relationship models on the front-page, entry screen or wherever a user of the Data Dictionary first 'hits' (This provides a meta layer to the detail beneath).</p> <p>Then for each table:</p> <p><strong>Table Name</strong> [Physical | Logical]</p> <p><strong>Table description</strong> (content, granularity, 'periodicity' (if there is one, the time period which applies to the data contained in the table), source)</p> <p>Then for each column:</p> <blockquote> <blockquote> <p><strong>Column Name</strong> </p> <p><strong>Column Description</strong></p> <p><strong>Column Datatype</strong> </p> <p><strong>Column Size in Bytes</strong></p> <p>[Optional] <strong>Other Column Details</strong>... nullable, triggers, source </p> </blockquote> </blockquote> <p><strong>Relationships</strong> Constraint name | 'Other' Table | Cardinality | Type etc.</p> <p><strong>Indexes</strong> Name | Column Membership | Type etc.</p> <p>...Obviously, that's a 'less is more' approach to defining a data dictionary! I think the key is providing an easy way in (through the ER) model, rather than just a long, labourious list of tables and columns.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
