 /**
  * Constructor creates and initializes the meta data object create DS object per table
  *
  * @param tableNames - String array of database table names ,It can be zero element array
  * @param singleService - select the service generation mode true one service for whole database
  *     when it false services per table wise
  * @param dataSourceId - carbon datasource id it can be null
  *     <p>When create the connection there are 3 away to do it , First way is provide the relevant
  *     information(url, driver, username, password) which need to create connection that time
  *     other fields(connection, datasourceId) should be null
  *     <p>Second way directly you can provide connection instance
  *     <p>final way is you can provide carbon datasource id(name)
  *     <p>if you wish to use all the tables of database you can provide zero element array
