Applications Of Logic Programming

logic programming is used in 

1.Relational Database Management Systems:

• These are the systems which stores the data in the tabular form.

• Relational calculus is used to perform queries on such databases.
• Those query-languages are non procedural which means ,in that user doesn't need to explain the process of retrieving an output but only describes the characteristics of the output.
• "prolog structures'' are used to describe the information present in the tables and the "prolog rules" explains relationships between the tables.
• The resolution operation contains the retrieval process.
• The queries for the RDBMS can be provided by the prolog goal statements.

Advantages:-

1. Single language is required for the implementation of RDBMS.
2. All the Queries related to data definitions,data manipulations and input and output functions can be found by using a single logic programming language.
3.  Deductive capability is built in the logic programming languages,which is helpful for implementing RDBMS.
4. deducing the data from the conventional RDBMS is not possible as it is only contains the facts but not inference rules.

Dis-Advantages:-

1. use of logic programming for implementing the RDBMS is a slow process.

2.Expert Systems

expert systems are the computer systems which had been developed for imitating human expertise in some domain.

• They consists of database of facts an inferencing  process along with some heuristic and human friendly interfaces.

• the problems of incompleteness and inconsistencies of the databases in expert systems can be solved by using logic programming.

• The knowledge needed for expert systems was provided by the polog.

• They can grow dramatically because these can learn from the process being used.

• prog can be used to build the expert systems because it uses the resolution for processing queries for adding facts and rules for enhancing the learning capabilities.

3.Natural Language Processing:-

• It uses the logic programming in providing interfaces to a computer software systems such as intelligent databases and knowledge based systems etc.,
• it helps in describing the language syntax
• set of sentences in natural languages can be expressed in clausal form by the logic-based semantics networks.
• some semantics in natural language can be efficiently modeled by employing the logic programming language.
• the proof procedures in logic programming are similar to certain parsing technique.

4.Education:- 

logic programming such as micro prolog  can be used in the field of education which provides the following advantages:-

• it introduces computing.
• it's is easy to teach logic programming to the starters rather than the experienced individuals.
• it helps in  the students in clear thinking and expressions.
• it helps in solving the mathematical problems,equations,understanding the grammar of natural language and the rules of the physical world.
