// Class Description : This is the test procedure for verification of the dbJAPI Update capability. 
// 
// Two connections are used in this test, namely postgres and MS-SQL. There are other connections, which have been 
// commented out for your reference. 
// 
// The test first updates the postgres db, then it selects the updated records and updates the MS-SQL with them. 
// At the end the updated records are verified using maps created from the processed records of the postgres table.
