Getting Startedwith pureQuery

Chapter 1 – Introduction to pureQuery 41
Because coding in JDBC is so tedious, it only makes sense that Java developers would
turn to frameworks such as Spring, iBatis (now called myBatis), and JPA to help with their
object-relational mapping, among other things. pureQuery does provide productivity boosts
that many are looking for in a Java framework, but it does not provide the full persistence
or container management associated with Hibernate or JPA. As a framework alternative,
pureQuery attempts to provide a balance point between enhanced productivity and full
SQL control.
However, pureQuery is different from other frameworks in that it can complement any
existing framework. Developers can continue to use their framework of choice and add
pureQuery to get the added benefits of performance enhancement, improved security, and
improved manageability. Integrations with other frameworks are described in Part V.
Of course, if you are writing new applications and don’t require full container management,
then pureQuery is an excellent choice in terms of performance and productivity when your
data is stored in DB2, Informix Dynamic Server, or Oracle databases.
As shown in the figure above, pureQuery attempts to provide the best of both worlds:
• It gives the developer the ability to fully control the SQL where needed
• It helps the developer create good SQL without having to learn a new query
language
• It offers a very simple API
• It provides basic object-relational mapping at development time, with no need to
map complex relationships between entities and objects
• It can provide performance, security, and manageability benefits to those who
continue to use full persistence frameworks, using client optimization.
As mentioned earlier, pureQuery can use client optimization to take any existing Java
application, even if coded in a framework, and “uplift” it so that those applications can
obtain many of the same benefits they would get when coding to the pureQuery APIs,
notably static SQL and enhanced visualization for improved problem determination. The
client optimization technology can help regardless of whether your application is a
complicated Hibernate application or an out-of-the-box Java/JDBC program for which you
may not even have the source code.
