1. A method of importing a first data model into a meta-data representation in one or more computers, comprising: (a) invoking an import wizard comprising a graphical user interface that guides a user through a step-by-step process of importing the first data model into the meta-data representation, wherein the meta-data representation comprises a relational database management system (RDBMS); (b) selecting a source, using the import wizard, that specifies connectivity information of a source containing the first data model to be imported; (c) selecting a schema, using the import wizard, from the selected source, from which tables will be imported into the meta-data representation; (d) retrieving and displaying, using the import wizard, a list of all table names within the selected schema; (e) selecting, using the import wizard, one or more tables from the list of all table names to import into the meta-data representation; (f) selecting, using the import wizard, an option to add all data types and tables from the first data model to the meta-data representation, wherein the selected option enables an automatic addition of all data types and tables from the first data model to the meta-data representation without the user having to specify a reconcile action for each data type and table; and (g) importing the first data model into the meta-data representation by populating table information for all of the selected one or more tables into the RDBMS based meta-data representation.
