Post-Relational Limited specialise in Pick, IBM uniVerse/Unidata, and SB+ programming tools on Unix, Linux, and Windows platforms. Post-relational databases are often known generically as Pick or Pick-like (after the late Dick Pick), nested, extended relational, multidimensional, or multi-valued, and provide a highly flexible and efficient environment for application development, datawarehousing and OLAP tools.

 

For discussions, questions, and informed debate on all Pick-like products, go to comp.databases.pick on Google. The IBM U2 User Group site has news and discussions about all IBM U2 products, and the IBM U2 developerWorks site has some excellent technical content on the U2 product range.

 

International Spectrum publishes its long-running magazine every two months, and organises annual technical conferences. Database Trends and Applications publishes a regular "5 minute briefing" on news in the multi-value market.
