Sample text

Similarly, any of (S ) denotes one arbitrary element schema, and n of (S ) denotes an arbitrary selection of n of the element schemata. – The selection of subschemata in the collection using any of the constructors all of , any of or n of can be refined by adding selection criteria in form of a where-clause. For instance, n of ({S1 , . . , Sk }) where ϕ would select n of the element schemata among those satisfying the condition ϕ. – n th(S ) for a list or tree schema denotes the n’th element schema, provided 1 ≤ n ≤ k is satisfied.

However, lots of similarities, repetitions, and similar structuring elements appear in such schemata. In this paper we presented an algebra for handling meta-structures that occur frequently in such schemata. The metastructures as such have already been identified in our previous work, and classified according to structure, lifespan and context. The work presented now highlights the solid formal background of the meta-structuring approach in database schema modelling and maintenance. In particular, the meta-structuring approach aims at supporting componentbased schema development, in which schemata are developed step-by-step on the basis of the skeleton of the meta-structure.
