Brian Storm:

[metadata+] repository: What's a metadata+ repository? Usually, either a database is structure oriented, e.g., DB2, Oracle, PSE etc.; or semi-structure oriented, e.g., Lorel, Rochade, etc. They are either very efficient on organizing a large amount of data, but very poor on restructing, or very efficient on restructuring, but poor on large amount of data. Is there any database system that can be both good on managing large amount of data and also the restructuring? That's a database on top of other databases, it has all kinds of import and export functions on both the metadata level and the data level of other database systems. It can "understand" other databases, and can work with them. I call this metadata+ database system, that is used to clean, integrate, and restructuring user's data stored in other database systems.
