  1. BEA Experience with NAWWE Brent R. Moulton OECD, Working Party on National Accounts Paris November 4, 2009

  2. Background • Since BEA’s first submission of SNA 93 data in 2000, the data submission has been based on spreadsheets with a gradual increase in details and metadata. • Process involved exporting data to spreadsheets—a time-consuming and often error prone process. • Before exporting to Excel, data were stored in time-series databases (Aremos and Fame).

  3. BEA implementation of NAWWE • To translate from these time-series databases to a relational database, we used NAWWE start-up files to reorganize the data. • In the process of reorganizing the data, several smaller time-series databases were consolidated. • An SQL relational database was constructed using NAWWE table codes to form the core identities. • A test submission was provided for 2000–2007. After OECD provided feedback, we resubmitted in mid-2008.

  4. Comments and plans • BEA intends to continue its participation in NAWWE with our upcoming submissions. • BEA received useful feedback from OECD. • Timely communication and participation by other statistical offices would be useful. • Transforming our time-series data into a relational database allowed BEA to identify redundancies and inconsistencies.
