318 Getting Started with IBM Data Studio for DB2 Figure 11.3 – InfoSphere Data Architect for data modeling For more information about InfoSphere Data Architect, see the ebook Getting Started with InfoSphere Data Architect which is part of this book series. 11.2.2 Develop: Data Studio and InfoSphere Optim pureQuery Runtime For data-oriented developers or database administrators, Data Studio contains all the database administration and data development capabilities a database developer needs. But is goes beyond the basics for Java development when used with InfoSphere Optim pureQuery Runtime. Data Studio ramps up Java development to new levels for heterogeneous databases. The data access layer generation includes support for the standard Data Access Object (DAO) pattern and leverages the pureQuery API, an intuitive and simple API that balances the productivity boost from object-relational mapping with the control of customized SQL generation. It also simplifies the use of best practices for enhanced database performance such as statement batching and static execution. InfoSphere Optim pureQuery Runtime is used with pureQuery data access layers. For both pureQuery and other Java applications that might be using Hibernate, JPA, or some other framework, you can take advantage of the great features in Data Studio, as shown in Figure 11.4.
Chapter 10 – Developing data web services 319 Figure 11.4– Data Studio has advanced features for Java database development and tuning As shown in Figure 11.4, one great feature is the ability to correlate SQL with the data sources and with the Java source code, even if the SQL is generated from a framework. This can really help you understand the impact of changes, and can also aid database administrators and developers in identifying and tuning SQL when using output from the DB2 package cache during QA or production. You can start learning about SQL performance issues by visualizing SQL “hot spots” within the application during development by viewing performance metrics about how many times a statement is run and the elapsed times. Adding InfoSphere Optim Query Workload Tuner to your environment can help you tune you SQL by providing expert guidance and rationale to build your tuning skills. In addition, because of the integration with other products, Data Studio helps developers be cognizant of sensitive data. For example, developers can readily identify sensitive data based on the privacy metadata captured in InfoSphere Data Architect. They can create test databases directly from test golden masters or can generate extract definitions for InfoSphere Optim Test Data Management and InfoSphere Optim Data Privacy solutions to create realistic fictionalized test databases. The physical data model is shareable among InfoSphere Data Architect, Data Studio, and InfoSphere Optim Test Data Management Solutions to enable collaboration and accelerate development.
