EViews Enterprise offers all the features of the Standard Version of EViews 10, but also provides flexibility to directly connect to different data sources. Whether you want to connect to a third party vendor, use ODBC to connect to a relational database, or use EViews’ Database Extension Interface (“EDX”) or EViews’ Database Object (“EDO”) Library to connect to your propriety data sources, EViews Enterprise is the tool for you!
With EViews Enterprise, you will improve your work efficiency by minimizing the steps needed to bring data into your EViews workfile and improve modeling accuracy with the most recent data from your direct connection to your data source.
With EViews Enterprise and an account with your data provider, you can seamlessly search, query, and retrieve data from third-party data sources such as Bloomberg databases, IHS databases, FactSet databases … and many more.
|You can drag and drop from a third party vendor directly into your workfile.
ODBC Compliant Databases
Enterprise Edition allows direct access to any database with an ODBC driver, providing transparent connection to common relational databases such as Oracle, Microsoft SQL Server, IBM DB2, or Sybase.
|ODBC can connect you to your own private databases.
The EDX API provides an open programming interface that allows users to develop their own customized connection to any public or proprietary data source providing simple and immediate access to the data within EViews.
|EDX allows you to build your own data browsers for your data.
The EDO library allows you to work with data stored in EViews file formats from within other applications. EDO makes it simple to pull the finished results of your work directly from your EViews workfile, or to write a simple application to regularly update your EViews database from an external data source.
