Schema validation and view updating are database engineering problems which seem to
differ significantly. Hence, for solving them, significantly different approaches are taken …

Two different approaches have been traditionally considered for dealing with the process of
integrity constraints enforcement: integrity checking and integrity maintenance. However …

We deal with view updating and integrity constraint maintenance. View updating is
concerned with translating a request to update derived facts into updates of the underlying …

In this paper we address the explicit construction of (complex) update programs from basic
update operations like" insert tuple" and" delete tuple'. The main contribu tion is the …

An important problem that arises when updating a deductive database is that of integrity
constraint maintenance. That is, given a consistent database and an update request, to …

We show that database schema validation and update processing problems such as view
updating, materialized view maintenance, integrity constraint checking, integrity constraint …

Two interrelated problems may arise when updating a database. On one hand, when an
update is applied to the database, integrity constraints may become violated. In such case …

An important amount of research has been devoted to consistent view updating. In this
paper we propose a new approach to deal with this problem. Our approach is aimed at …

Data warehouses are huge repositories designed to enable the knowledge workers to make
better and faster decisions. Due to its significance in strategic decision making, there is a …

In this article, we will discuss a set of applied solutions related to creating a set of data
constraints, which allow organizations to organize their work in terms of using information …
