Overview of Greenplum Database

Greenplum Database leverages a share-nothing Massively Parallel Processing (MPP) architecture which facilitates analytical, Business Intelligence and data warehouses processing, all built on top of commodity compute and storage nodes to deliver extreme performance in a cost-effective manner. The Greenplum Database architecture provides automatic parallelization of data loading and queries. The high-performance loading uses Scatter/Gather Streaming technology, supporting loading speed greater than 10 terabytes per hour, per rack, with linear scalability. All data is automatically partitioned across all nodes of the system, and queries are planned and executed using all nodes working together in a highly coordinated fashion. The parallelism allows Greenplum database to achieve high read-write performance.

Overview of Toad for Data Analysts

Toad is a software tool used for development and administration of databases. The Toad for Data Analysts is designed for powerful multi-platform querying and reporting capabilities with databases, for example, Greenplum database – all from a single interface that automates and streamlines time-consuming tasks. The Toad for Data Analysts makes it simple to query, compare, synchronize, consolidate, cleanse, and analyze data. Toad for Data Analysts accelerates the creation of data sets and queries with data cleansing capabilities. It also enables users to apply advanced statistical analytics and visually analyze and profile data. Users can also explore the database, build queries, browse data, and create database diagrams and more. For example, ER Diagrammer and Data Browsers in Toad for Data Analysts can visualize table relationships, view master-detail relationships and browse database objects from Greenplum databases.

How Toad for Data Analysts and Greenplum Database work together

Pre-requisite In order to get started, the user will need to prepare the following components: • A version of Windows that supports the v3.5 .NET engine • The Greenplum Connectivity Pack 4.1.2 or later • Toad for Data Analysts v3.0 • Greenplum Database v4.2 • The referential integrity of any tables should be retained

Connection After the user installed and configured the Greenplum Connectivity Pack, the user will need to add a new User DSN in Control Panel -> ODBC Data Source Administrator with the new ODBC driver that you installed by Greenplum Connectivity Pack. For instance, the user can choose the PostgreSQL Unicode driver to Configure and test with a working Greenplum Database.

After the user installed and configured the Greenplum Connectivity Pack, he/she needs to add a new User DSN in Control Panel -> ODBC Data Source Administrator with the new ODBC driver that you installed by Greenplum Connectivity Pack. For instance, the user can choose the PostgreSQL Unicode driver to Configure and test with a working Greenplum Database. Assuming the user has already run the installer and installed Toad for Data Analysts 3.0 correctly, now he/she can start using Toad for Data Analysts for Greenplum Database. First, the user needs to create a new connection for Greenplum Database. There is an ODBC icon inside the Navigation Manager. Here are the steps to create a new connection for GPDB: a) Right Click the ODBC icon, choose Create

9


b) Fill all the database connection information & check on Save Password. Use the Connect button to test the connection. Once the connection is verified, use the Save button to save the connection details.

10


Object Explorer & Object Viewer Now the user can use Toad for Data Analysts to connect to Greenplum Database. He/she can use the Object Explorer to explore what tables, views, procedures, catalogs are resided in GPDB.

User can view the simple table structure by just choosing the tables in the Object Explorer.

11


User can right-click the table and choose View Details to see the details of the table like Columns, Data, Indexes, Primary Keys, Foreign Keys, Privileges and Scripts.

By choosing the Data tab, user can view the data populated to that table.

The Object Viewer shows all of the properties for the object selected in the Database Browser. The information and operations the user will be able to access here will be directly impacted by the security privileges setup for the account he/she are using. Toad itself does not restrict the user from making changes to the data or objects in the Greenplum Database.

12


Query Builder Users can also create a visual query in Greenplum Database using Query Builder. Query Builder is located at the main menu: Tools -> Query Builder. User can just drag and drop the objects/tables directly to the Query Builder main window. Users can build their visual Greenplum Query by using the diagram or writing SQL directly. Users can choose a particular table for query by drag and drop, and choose particular columns by double clicks on those columns.

13


Then, he/she can view the generated query on the Query Tab:

Diagram The user can create a database diagram, such as ER diagram for Greenplum database. Users can take the advantages of discovering entity data relationships, add his/her own relationships and add notes to specific entity by simple operations like drag and drop.

14


Conclusion

In this white paper, the interoperability of Greenplum database and Toad for Data Analysts is discussed and demonstrated. Using Toad for Data Analysts with Greenplum database gives the user power data analytic, query and reporting capability that includes simple setup along with an intuitive graphical interface customarily found when using TOAD products.
