<p class="para">JDBC coding is widely acknowledged as verbose. It isn't complicated code, but there tends to be a lot of it in most applications. Consequently, a number of products have been invented to reduce the amount of code (and the time spent on development and maintenance) for data access objects. These products have achieved mixed success in the marketplace. The bottom line is that they generally don't achieve enough code reduction to pay for their learning curve and performance overhead.</p>
<p class="para">This section lists the most prevalent products and where to get more information about them. Although I don't use these products or recommend them, I think every technical architect should be aware of their existence.</p>
