Deductive database examples

  • What is the feature of deductive database?

    Deductive databases offer elegant and powerful ways of managing complex data in a declarative way, especially for information that is derived by use of recursion.
    Deductive systems typically provide a declarative query language such as a logic programming language (e.g., Prolog)..

  • Why is a deductive database important?

    Deductive databases offer elegant and powerful ways of managing complex data in a declarative way, especially for information that is derived by use of recursion.
    Deductive systems typically provide a declarative query language such as a logic programming language (e.g., Prolog)..

  • In contrast to deductive rules, active rules support re active behavior like triggering of updates as a response to external or internal events.
    Conceptually, most rule languages for active database systems ADBs are comparatively low- level" and often allow to exert explicit control on rule execution.
  • In today's world as we deal with a large amount of data, this deductive database provides a lot of advantages.
    It helps to combine the RDBMS with logic programming.

A deductive database is a database system that can make deductions (i.e. conclude additional facts) based on rules and facts stored in its database.

Are deductive databases more expressive than relational databases?

Deductive databases are more expressive than relational databases but less expressive than logic programming systems such as:

  1. Prolog

In recent years, deductive databases have found new application in data integration, information extraction, networking, program analysis, security, and cloud computing.

How to design a deductive database?

To design a deductive database a purely declarative programming language called Datalog is used.
The implementations of deductive databases can be seen in LDL (Logic Data Language), NAIL (Not Another Implementation of Logic), CORAL, and VALIDITY.
The use of LDL and VALIDITY in a variety of business/industrial applications are as follows.

What is a deductive database in Prolog?

Datalog, which is the language underlying deductive databases.
Deductive databases are an extension of relational databases which support more complex data modeling.
In this section we will see how simple examples of deductive databases can be represented in Prolog, and we will see more of the limitations of Prolog.
