<p>The present invention relates to an indexing method and system for relational da-tabases, wherein a foreign key reference is routed by providing in a first table a reference to a second table referring to said first table. Thus, foreign key refer-ences to second tables are traversed via the index of the first table, such that a referential integrity can be implemented more easily and memory space can be saved. Furthermore, a key information is proposed to be removed from a row as it is inserted in a relation table, wherein the key information is obtained from an in-dex structure by a deduction operation. This leads to a further deduction of the required memory space.</p> |
