Contextualization

X

XML collection /XML database

Spreadsheets

Some Database

RDBMS A

RDBMS B


Geodataspace bringing the dataspace vision to geodata

Contextualization

Spreadsheets

Some Database

RDBMS A

RDBMS B


Geodataspace bringing the dataspace vision to geodata

Data Integration

  • Two main currents:

  • Classical integration

  • ‘Pay-as-you-go’ integration

1975

Classical Integration Strategy

Application

Meta-DBMS

Global Schema

RDBMS A

RDBMS B


Geodataspace bringing the dataspace vision to geodata

Classical Data Integration

  • Problems

  • Heterogeneity -> Costly upfront schema mapping/alignment

  • Explosion of sources - > Maintain a Global Schema is VERY HARD!
