Database Parser and Token generator Client : Amalgamated Software Applications Environment : C++ Role / Size : Individual Duration : Dec ’03 to April ‘04 Role: Designed and Implemented parser and token generator in C++ Description: Parser will be responsible for parsing the SQL Statements. Parser will parse the SQL Statements according to SQL-99 specifications grammar and syntax rules. Parser will create a tree-type object containing all the information about the query. The tree type object will be representing different rules of the SQL grammar and parser will be initializing the classes with the corresponding info from the query. Parsing SQL statements: Any grammar can be divided into two parts, mainly tokens and rules. Tokens are the smallest individual and indivisible part of the grammar. Tokens placed in a sequence define a rule. Rule can also have other rules in its sequence. Parsing a query will involve token generation, checking for grammar rule and finally making a tree-type object corresponding to the satisfied rule and loading query information in the object. Token generation will involve breaking of query into tokens using the grammar. After tokens are generated, parser will match the first token of the query with first token of the grammar rules. Rule whose first tokens matches with query token will be selected and parser will match the next token of the query with next token in the rule. Parser will repeat the procedure and tries to match all the tokens with the tokens in the query. If all the tokens match, parser will create a tree-type object and load these tokens information into the object. If all the tokens didn’t match, parser will check the next rule of the grammar. If all the rules of the grammar are checked and no rule satisfies the given query, parser will throw an error. Point Of Sale Client : Amalgamated Software Applications Pvt Ltd.
