low-cost, high-performance data warehousing

problem: the high cost of ETL

When developing high-performance data warehouses, few organizations can afford to avoid the compromises involved in any single approach to data integration. ETL offers the ability to capture, trace and reuse valuable metadata in process flow and business logic, and commercial ETL tools have evolved into data integration suites, offering sophisticated features and functionality, such as metadata repositories, data lineage, profiling, governance, impact analysis and configuration management. But most ETL tools are prohibitively expensive and custom-coded ETL solutions can fall short in features, functionality and stability.

Choosing to leverage your data warehouse appliance for ELT (extract, load and transform) can offer higher performance and lower cost than ETL, as well as a familiar coding environment (SQL). But you also forfeit ETL’s metadata benefits, and the custom code required to perform data extractions and transformations can be difficult to maintain.

expressor solution: intelligent load & go^tm for Netezza

expressor/Netezza intelligent load & go combines the affordable expressor semantic data integration system with Netezza’s high-performance data warehouse appliance to remove the cost barrier to high-performance ETL and allow organizations to choose the data warehouse architecture most appropriate for their specific applications.

The expressor/Netezza intelligent load & go solution allows you to rapidly develop affordable, high-performance data warehouses and data marts.

Intelligent load & go leverages expressor’s collaborative, role-based environment to encourage best practices in development and data governance by allowing developers, architects, data stewards and analysts to share a common semantic metadata repository. expressor’s unique metadata rationalization process promotes greater reuse of business rules and shortens development time by removing the need for developers to “type-cast.” expressor data-flow drawings use the semantically rationalized field names, and the expressor system automatically performs all type conversions, meaning developers need not code one-to-one mappings and can therefore concentrate on rules that actually require transformation. 

For maximum throughput, expressor also includes an “nzload motor” that integrates seamlessly with the Netezza nzload bulk loader. And expressor is committed to maintaining tight integration with new versions of the Netezza appliance.

benefits: exponential business intelligence

• choosing the best data warehouse architecture for your business, thereby reducing your overall costs
• eliminating the need to compromise on any of your data warehousing and integration needs –whether they include data lineage reporting, data quality gates, through to aggregations and data mart generation
• greater re-use, shorter development times and improved data governance as expressor learns more about your business in subsequent applications and the semantic rationalization process becomes increasingly automated
