External Connectivity
EViews offers several methods for interacting with external applications and data:
The EViews OLEDB driver provides an easy-to-use interface for external programs to read data stored in EViews workfiles (WF1) and EViews databases (EDB) (“The OLEDB Driver”).
The EViews Excel Add-in offers a simple interface for reading data stored in EViews workfiles and databases from within Microsoft Excel (“The Excel Add-in”).
The EViews Database Objects (EDO) Library gives you the ability to access data objects held inside EViews databases and workfiles from within an external application (“EViews Database Objects (EDO) Library”).
EViews offers COM Automation server support so that external programs or scripts can launch or control EViews, transfer data, and execute EViews commands (“EViews COM Automation Server”).
EViews offers COM Automation client support for MATLAB and R application servers so that EViews may be used to launch and control the application, transfer data, and execute commands (“EViews COM Automation Client Support (MATLAB and R)”).
EViews offers an EViews Database Extension (EDX) interface for developers who wish to provide EViews access to their database formats. Any external data source that implements this interface can be opened directly from within EViews Enterprise Edition and used just like an EViews database (“EViews Database Extension Interface”).
