Abstract DBAs and developers working with IBM® DB2 often use IBM® Data Studio®. Toad™ DBA Suite or IBM® DB2 LUW complements Data Studio with advanced features that make DBAs and developers much more productive. This document explains some of these features and compares them to Data Studio’s functionality.
Introduction Toad™: focused on the needs of its users Toad is the most widely used database management solution on the market today, with more than two million users. Toad brings operational efficiency and best practices to DBAs and development teams working through the database lifecycle. Toad for IBM DB2 was introduced in the market to solve challenges in IBM DB2 LUW and z/OS development and administration. From the very beginning, Toad’s development team has collaborated with the user community, and many of
Toad’s advances over the years have been derived directly from that community. Today users can submit suggestions and vote on the ideas of others at the Toad Idea Pond, so that the best ideas make it into future releases. Toad users also want to become more proficient at the tasks they perform on a daily basis, and to share their expertise with others. Toad World connects the community of users together to discuss, share and learn more about IBM DB2 and Toad through videos, blogs, white papers and more. Through this collaboration, Toad users can get the most out of the product. About this document This technical brief will help you understand how Toad DBA Suite for IBM DB2 LUW v5.5 complements and extends the basic features available in IBM Data Studio. The Data Studio product used in this comparison is IBM Data Studio – Full Client version 3.2.0.0.

such as script map, advanced code completion and code snippets make you more productive in developing queries. Running the same scripts against multiple databases Users often need to run the same scripts against multiple databases. You can easily do that in Toad with the Group Execute feature of the Editor, as shown in Figure 3.
Exporting and saving data with Data Studio Many times developers and DBAs need to export and reload data from their tables, and they need many different file formats to be supported. With Data Studio, you can export data directly from a table into a few delimited formats, as shown in Figure 4.

IBM Data Studio also supports advanced alterations; however implementing object changes is not straightforward and is often confusing. At times, the object list in Data Studio becomes a change plan grid that is needed to implement object changes. Moreover, it is unclear if any type of recovery script is possible with Data Studio. Figure 50 shows objects with changes and objects that do not have changes.
Figure 51. Toad’s mapping features provide powerful name transformations.
Mitigating the impact of planned database changes DBAs often manage multiple DB2 database environments that need to be kept in sync, which requires accurate schema deployment scripts. Only Toad has the advanced features you need to easily keep your environments in sync. These features include object compare, schema compare, object migration and DB/DBM parameters compare. Object compare lets you compare and sync database level and schema level objects across your environments. Toad’s
mapping features allow you to compare objects in two environments that might have different naming conventions. Only Toad’s object compare feature has advanced mapping features (see Figure 51) which provide powerful name transformations. Only Toad provides an easy to understand, comprehensive change summary that allows you to see changes between your objects before they are implemented (see Figure 52).
