HCL INVENTS A NEW DATA QUERY LANGUAGE FOR THE WORLD’S LEADING AVIATION COMPANY 3 The customer is the world’s largest aerospace and defense company primarily providing avionics and information technology systems to governmental agencies and aircraft manufacturers. The customer wanted to optimize its database and improve database query performance. Prem Sundar a highly skilled database professional with HCL Technologies, manages product lifecycle for ASCENT–a tool that the customer uses for capturing avionics Data. The captured data used to get updated on Objectivity, However, querying data from this database wasn’t an easy task, To retrieve data from the database, the team had to write a new code for the query. The innovative idea saw an over- whelming response from the customer, who has saved $5.02 mn revenue which was wasted before. The language is now customer’s intellectual property and their filling a patent for the same. The techy insight of Prem made him come up with an idea of new query language and spent 18 months for developing it which resulted in AQL (Ascend Query Language), using which a query code could be written in just five minutes, For AQL he designed & developed; a parser that understands the query syntax; a query engine that outputs data based on the query; and a client user interface.
