Subject: A Point of View on ORDBMS

Abstract. The paper deals with the logical representation of objects in database by means of two object-relational languages: SQL3 and Zigzag. The three criteria,

  • complex data
  • type inheritance
  • object behavior,
are suggested to classify RDBMS or DBMS as ORDBMS or ODBMS correspondently. We conclude that Zigzag language correlates with object SQL at least in object-oriented data representation. Zigzag is more expressive and helps to work with structurally more flexible data. Nevertheless, SQL3 with its type schematization allows to set more strict control of uniform data.
