The driver models the data in eBay into a list of tables that can be queried using standard SQL statements.
Generally, querying eBay tables is the same as querying a table in a relational database. Sometimes there are special cases, for example, including a certain column in the WHERE clause might be required to get data for certain columns in the table. This is typically needed for situations where a separate request must be made for each row to get certain columns. These types of situations are clearly documented at the top of the table page linked below.

|ItemListing||Update, delete, and query Item Listings for sellers.|
|ItemVariations||Item Variations are multiple similar (but not identical) items in a single fixed-price listing. For example, a T-shirt listing could contain multiple items of the same brand that vary by color and size; each variation would specify a combination of one of these colors and sizes. Each variation can have a different quantity and price. You can buy multiple items from one variation at the same time. (That is, one order line item can contain multiple items from a single variation.)|
