Operating Systems and Hardware
The Business Basic Programming language used by CSI to implement business solutions runs on an interpreter that can reside on a variety of operating systems, such as, UNIX, Linux, Microsoft Windows, and other proprietary operating systems on a wide variety of hardware platforms.

The use of Client/Server Technology coupled with 3GL and Object Oriented 4GL development environments allows diverse company and departmental requirements to be implemented.

CSI can help clients with the selection of hardware and software, installation, configuration and training.

In addition, our custom programming incorporates unique client business rules, which allows all data entry and management reporting requirements to be met. To accommodate rapidly changing business environments, the Business Basic language is used, as it allows program modifications to be immediately implemented.
