Think you have the right Data-Type?

Selecting the right Data-Type (DT) for data is key to efficient data storage, retrieval and processing, with over 30 different DT to choose from this isn’t as straight forward as you might think, have your also considered the usage pattern of the data in addition to its storage requirements This session explores the various data-types now available, we look at conversion’s between different DT’s as well as index sizes & effectiveness, compression and other factors can that influence these decisions, we finish off by discussing different approaches on ‘migrating’ a DT to a different DT, throughout the session we consider any performance considerations, such as when implicit conversions occur and more

Data Architecture underpins just about everything we do in IT. Without a clear understanding of how data is structured, there is no reliable way to derive meaning from it. Data Architecture drives the design and governance of data systems, and thus should be of interest to any data professional. Data Architecture provides the blue-prints that we all share, whether we be DBAs, data integration developers, database developers, data warehousing professionals, data presentation developers or client-side application developers persisting data for later retrieval.
