MIP–CUP
(new primary key)
NORMATIVE APPROACH
MIP: Monitoring system of public investment (Monitoraggio Investimenti Pubblici), established by the Interministerial Committee for Economic Planning in order to produce timely information on the implementation of development policy (L.144/99).
CUP: Project primary key (Codice unico di progetto), required for each new or on-going project as of 1st Jan 2003 (L.3/03).Must be quoted in every administrative and accounting document, both paper and digital, regarding a public investment project and must be reported in every database related to the above projects (Reg. 24/04).
INFORMATIONAL APPROACH
Recognition of information related to same projects in different data repositories: each repository usually represents the same item in a specific format so that it is virtually unfeasible to find a common variable across different repositories and create an automatic join between information on the same project.
Integration of the related information: as the relevant information on a project is dispersed across several databases, some rules must be defined in order to merge it all into a single repository.
