Shahid Naweed Department of Computer Science and IT, The Islamia University of Bahawalpur E-mail: shahid_naweed@hotmail.com Abstract To write technically correct SQL queries is a complex and skill requiring task especially for a novel user. This situation becomes more complex when a low skilled person has to use a database management system for a specific business purpose. S/He has to write some quires at his own and perform various tasks. This scenario requires more expertise and skills in terms of understanding and writing the accurate and functional queries. The task of the novel user can be simplified by providing an easy interface that is well known to that user. In order to resolve all such issues, automated software is needed, which facilitates both users and software engineers. User writes the requirements in simple English in a few statements and the designed system has the ability to analyze the given script. After composite analysis and mining of associated information, the designed system generates the intended SQL queries that can be run directly. The paper describes a system that can create SQL queries automatically. The designed system provides a quick and reliable way to generate SQL queries to save time and budget of both the user and system analyst. Keywords: Information extraction, Automatic Query Generation, Knowledge Retrieval, Natural language processing. 1.0. Introduction Relational databases are the premier way of storing common data repositories. After storing the data contents in a database, an interfacing mechanism is required to talk with the prearranged repository of the confined data. The conventional way of communicating with a database is to fist build a connection stream and then adding, deleting or updating the data contents in the database by using a standardized interfacing mechanism [1]. Simple command shells are typically used and they are often incorporated within every distinct database product. These command shells are typically simple filters which helps a use to log on to the database, execute particular commands and receive output. These command shells provide access to the database from the machine on which the database is actually running [2]. After hooking to a particular database a user or a programmer requires an interface and typically that
Database Interfacing using Natural Language Processing 845 interface is provided by some technical languages. These languages are called query languages and are constituted of the database commands typically used for asking questions to a distinctive database and getting intended response. SQL [3] (Structured Query Language) is the most popular query language which is actually the defacto language of databases today. SQL is an orthodox tool of database querying. Different database management systems implement this standardized language with trivial alterations and adjustments. However, in spite of these proprietary extensions by the vendors, the core of this querying language is the same in all of the environments. From an application programmer's point of view, the major novelty in the relational database is that one uses a declarative query language, SQL. Most computer languages are procedural. The programmer tells the computer what to do, step by step, specifying a procedure. Using SQL interface, the programmer defines his requirements and questions and the RDBMS query planner figures out how to get it [5]. There are two compensations of using a declarative language. The first is that the queries no longer depend on the data depiction. The RDBMS is free to store data according to its own design requirements [6]. The second major factor is improved software dependability. For various web-based and stand-alone applications the generic SQL is used to make the things simple and straightforward. Besides these praising compensations occupied by SQL, it’s technical and trifle interface makes this language monotonous and difficult to learn and use. It is quite intricate to remember these SQL commands and use them accurately and precisely. In order to resolve all such issues, an automated software is needed, which facilitates both users and software engineers. As far as this software is concerns the time, it takes to explore all the facilities and services, should be quite less than a minute and this information is quite useful for the users. 2.0. Problem Description Modern software engineering requires quick and automated solutions which may have ability to create the accurate and precise SQL queries automatically. For complex queries an expert programmer also requires assistance in terms of automatic query generation. He can use these queries after making appropriate adjustments and alterations in the automated generated queries with less effort in less time as compared to the traditional approaches. The task of the novel user can be simplified by providing an easy interface that is more familiar and well known to that user. In order to resolve all such issues, an automated software is needed, which facilitates both users and software engineers. User writes the requirements in simple English in a few statements and the designed system has obvious ability to analyze the given script. After composite analysis and mining of associated information, the designed system generates the intended SQL queries that can be run directly. The designed system has robust ability to create code automatically without external environment. The designed system provides a quick and reliable way to generate SQL queries to save the time and budget of both the user and system analyst 3.0. Used Methodology The understanding and multi-aspect processing of the natural languages that are also termed as "speech languages", is actually one of the arguments of greater interest in the field artificial intelligence field [8]. The natural languages are irregular and asymmetrical. Traditionally, natural languages are based on un-formal grammars. There are the geographical, psychological and sociological factors which influence the behaviours of natural languages [12]. There are undefined set of words and they also change and vary area to area and time to time.Due to these variations and inconsistencies, the natural languages have different flavours as English language has more than half dozen renowned flavours all over the world [14]. These flavours have different accents, set of vocabularies and phonological aspects. These ominous and menacing discrepancies and inconsistencies in natural languages make it a difficult task to process them as compared to the formal languages [13].
