ETL PARADIGM "PUBLISHES" GENE EXPRESSION DATA.NetGenics Inc., Cleveland, has introduced its NetGenics Gene Expression DataMart. NetGenics Gene Expression DataMart is a high-performance data repository See repository. that cleans, normalizes and integrates gene expression data from any combination of sources, including oligo-array, spotted-array, RT-PCR RT-PCR reverse transcriptase-polymerase chain reaction. See PCR1. , Taq-Man and many others. Employing a multi-dimensional data model, NetGenics Gene Expression DataMart expedites queries of multiple, disparate databases, returning results in seconds versus hours or days compared to other methods. Using an "Extraction-Transformation-Load" (ETL (Extract, Transform, Load) The functions performed when pulling data out of one database and placing it into another of a different type. ETL is used to migrate data, often from relational databases into decision support systems. ) paradigm borrowed from data warehousing See data warehouse. data warehousing - data warehouse , gene expression data is "published" into a single repository, normalizing diverse data and optimizing it for browsing and easy access. This integrated approach allows scientists to ask broad scientific questions across the various types of expression data owned or licensed by their organization. In contrast with the "wrappered" approach to database integration, where information retrieval information retrieval Recovery of information, especially in a database stored in a computer. Two main approaches are matching words in the query against the database index (keyword searching) and traversing the database using hypertext or hypermedia links. is slowed by the need to merge multiple queries and query results, NetGenics Gene Expression DataMart provides immediate access to requested data with a single query. Original data sources are not modified in any way, and if any of those data sources goes offline, the NetGenics Gene Expression DataMart remains accessible. "The ability to access clean data is an enormous advantage for the user, since errors in identification, classification, spelling, and vocabulary conformation con·for·ma·tion n. One of the spatial arrangements of atoms in a molecule that can come about through free rotation of the atoms about a single chemical bond. can severely hinder the discovery process," stated Richard Resnick, NetGenics director of Database Development. "NetGenics Gene Expression DataMart frees scientists to focus on science versus data integrity." NetGenics Gene Expression DataMart is component-based and will integrate with future domain-centric NetGenics DataMart solutions as they become available. NetGenics, Inc., is a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. that builds integrated informatics solutions for the life science market. The company's solutions leverage a combination of NetGenics proprietary software components and integration technology and consulting, support and development services. NetGenics was established in 1996 and is headquartered in Cleveland, Ohio. For more information, call (216)861-4007. |
