    <p>Disclaimer: Without knowing your business logic I could be completely wrong with some of the following suggestions.</p> <p>Ok a few things I saw in your database schema. </p> <ol> <li>Your cost center table looks to be both a lookup and association table. So if you have a set amount of cost centers lets say 5 for instance but a 1000 users then this table will have 5000 records which all store the cost center name (this is assuming that the cost center assignment is not unique to each user). You might want to split off the user association to a separate table which has it's own PK and FKs of costcenterId and userId.</li> <li>You inventory table, which I assume stores amount of stock on hand for an item, should only need an onhand quantities not sure what the description is for. If the description isn't unique to each item inventory you might want to split that off into it's own lookup table and reference it in the inventory table.</li> <li>You are storing "lineQuantity" in the vendor table. What is this column for. It sounds like it relates to a specific order in some way (quantity of item purchased?) If so you will want to split it off into it's own table and associate it with the order not the vendor. without knowing exactly what lineQuantity is though this suggestion could be completely wrong.</li> <li>Last suggestion not sure if this matters for your class. You are defining all your datatypes to be CHAR(10) you might want to change these to be the actual datatypes you would use for the database. </li> </ol>

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.
