public Feed(DataSource dataSource,
            String tablePrefix)
```
    Create a feed that reads tables over a JDBC connection. The connection should already be set to the right schema within the database.
    
    Parameters:
    
    tablePrefix - the unique prefix for the table (may be null for no prefix)
- Method Detail
  - validate
```
public ValidationResult validate()
```
    TODO check whether validation has already occurred, overwrite results. TODO allow validation within feed loading process, so the same connection can be used, and we're certain loaded data is 100% visible. That would also avoid having to reconnect the error storage to the DB.
  - getConnection
```
public Connection getConnection()
                         throws SQLException
```
    Returns:
    
    a JDBC connection to the database underlying this Feed.
    
    Throws:
    
    SQLException
