Free Webinar: Getting started with IBM Data StudioI'm still catching up on work after being away for my summer vacation... so forgive me for the lack of posts I've made! I saw this from Leon and would like to simply repeat it: A replay of this free webinar http://www.channeldb2.com/events/webinar-getting-started-with is now available. This is about FREE IBM Data Studio that naturally works with the FREE DB2 Express-C. One really important point. Recently we released "lite" versions of DB2 Express-C. These versions are faster to download but they are missing some of the components. One of those components is ... drum roll ... Control Center. Yes, you know Control Center is going away and is being replaced by the IBM Data Studio. So, watch the replay of the webcast, grab Data Studio, DB2 Express-C and the free books on DB2 Express-C and Data Studio. Susan |

Catalog view xmlstrings for simpler access to stringID informationThe XML support in DB2 is tightly integrated into the database engine and provides fast and sophisticated processing of XML data. In the past I had explained why - for compactness and speed - element and attribute names, namespace information is replaced with so-called stringIDs. The string to stringID mappings are stored in a cached dictionary which is persisted in a system catalog. That system |
