Data warehouse deployments are complicated enough without also having to deal with the deployment headaches associated with the use of data client libraries. Streamlined data access that communicates directly with the database not only eliminates the need to install, configure, and deploy client libraries for each database that must be accessed, but performs better while using less machine resources. Examples of this include:
- "Wire Protocol" ODBC drivers
- 100% managed ADO.NET data providers
- Type 5 JDBC drivers
