Methods And Tools Used

Compiler            

   The compiler that we are currently using is JDK 1.2.2.  This compiler may be downloaded at www.java.sun.com .

Tools                         

    The GUI interface for the XIB Broker Builder was created using the Java Foundation Classes.  This API may be downloaded at www.java.sun.com/products/jfc/index.html .    Most of the GUI was designed visually using IBM VisualAge for Java version 2.0.  A trial version of VisualAge may be downloaded at www7.software.ibm.com/vad.nsf .

XML Parser

    XML documents are parsed using XML4J version 2.0.15.  This parser may be downloaded at www.alphaworks.ibm.com/tech/xml4j .

HTML Parser        

    HTML documents from web based information sources are parsed and processed using WebL, a scripting language for automating tasks on the World-Wide Web.  Developed at Compaq, this language is imperative, interpreted and has built-in support for common web protocols.  The WebL software may be downloaded at www.research.digital.com/SRC/WebL/index.html .

Database Tools   

    Databases are accessed using JDBC technology, an API that allows users to access virtually any tabular data source form the Java programming language.  This API provides cross-DBMS connectivity to a wide range of SQL databases.  To perform queries, we use Mini SQL (mSQL) version 2.0.11, by Hughes Technologies.  This is a light weight relational database management system capable of providing rapid access to data with very little overhead.  The latest version of mSQL may be downloaded at www.Hughes.com.au/products/msql/ .
