a. Subsystems owned by CBM (Accounting system, MCH) b. PSSD System c. External related systems (MPU, T-Bond/Bill auction system, FX auction system) The Secure File Transfer Protocol (SFTP) will be used for file transfers. File formats supported by automatic data exchange will be XML, CSV, and PDF, where PDF will be used for report files. (B) File Upload/download Function via Web browser File upload and download functions similar to the existing CBM-NET functions will be implemented for some business additionally (please refer to Table 3-8), Once a file is uploaded via the web browser, the data from the file will be imported to the corresponding business. When the import is done, the function will notify CBM-NET responsible personnel for inspection. (C) Data Import Function The data import function will check the FTP server at a predefined interval and import data from the file to the corresponding business, such as credit/deposit funds settlement or T-Bond/Bill settlement information registration. When the import is done, the function will notify CBM responsible personnel for inspection. (D) Database Replication for Dashboard For the dashboard function to be added to the PSSD System, the PSSD System requires updated business data. A database server will be introduced to which business data will be replicated from the main databases of CBM-NET. Database replication will enable the PSSD System to access necessary data for the dashboard function. The following diagram shows the flow of data exchange after Phase 2 using (B) the file upload function. Files will be generated in specified format by related systems and will be sent to the FTP server in the CBM-NET system. CBM personnel will retrieve necessary files from the FTP server and upload data from the file to CBMNET by using the (B) file upload function. Once data is imported, CBM responsible personnel will be notified for data inspection and further processes. 70
