Metadata and relational databases

Metadata Clarification "There is an important difference and the reason why Xperanto is not about metadata integration is because it is based on DB2, and relational databases are not good places for storing metadata. The reason for this is that relational databases store tables which define entities. That is all they store. They also contain details about relationships that are defined by means of such things as foreign keys. However, these relationships are not explicitly stored in the database, which is why they are called relational, because that information is implicit."
