    struct RelationIdentifier {
       1: optional string databaseName;
       2: required string tableName;
       3: required string tableId;
    }
    
    struct ParentColumnTableRelation {
       1: required RelationIdentifier relationIdentifier;
       2: required string columnId;
       3: required string columnName
    }
    
    struct DataMapSchema  {
        // class name
        1: required string className;
        // relation indentifier
        2: optional RelationIdentifier relationIdentifire;
        // in case of preaggregate it will be used to maintain the child schema
        // which will be usefull in case of query and data load
        3: optional TableSchema childTableSchema;
        // to maintain properties like select query, query type like groupby, 
join
        4: optional map<string, string> properties;
    }
    
    struct TableInfo{
        1: required TableSchema fact_table;
        2: required list<TableSchema> aggregate_table_list;
        3: optional list<DataMapSchema> dataMapSchemas; // childSchema 
information
    }
    
    Inside column schema added ParentColumnTableRelation
