Tie-in is a relational data component library that lets you store and query records that can be related to any other record.

The relationships in a database are usually defined between columns across tables. In Tie-in, however, relationships can be defined between individual records. Relationships can also have types, so you can have multiple relationships between two records.

The ability to associate a record with any other record in any table opens up new possibilities that are hard to accomplish with conventional column-based relationships. In addition, since relationships are dynamic, no schema changes are necessary to define new relationships.
