dfd . After reviewing the proposed project, you saw the following: 1) Client is using OMS with Fidessa and is sending in drop copies of post trade messages from themselves as well as orders via FIX 4.2 protocol. 2) Fidessa OMS sends out pre-trade compliance checks back to client and gets the results back. 3) Post trade information is sent back to client in two ways: a) Batch file which is triggered at the end of the day and is placed on the Internet facing SFTP server managed by Fidessa. b) Post trade messages are sent to Fidessa hosted middleware in real-time and the results are sent to the client’s database via a Fidessa installed service in the client’s datacenter. The connection between Fidessa and the client is over a private circuit managed by Fidessa. Please create a simple and clean data flow diagram using any program of your choice for the scenario described. Please copy/paste the diagram here as a picture.

The proposed project involves the use of OMS (Order Management System) with Fidessa, a trading platform. The client is sending post trade messages and orders to Fidessa through the FIX 4.2 protocol. Fidessa OMS performs pre-trade compliance checks and sends the results back to the client. Post trade information is then sent back to the client in two ways.

Firstly, a batch file is triggered at the end of the day, which is placed on the Internet facing SFTP (Secure File Transfer Protocol) server managed by Fidessa. Secondly, post trade messages are sent to Fidessa hosted middleware in real-time. The results derived from the middleware are sent to the client’s database via a Fidessa installed service in the client’s datacenter. The connection between Fidessa and the client is established over a private circuit managed by Fidessa.

To depict the data flow in a simple and clear manner for the described scenario, a data flow diagram can be created. A data flow diagram (DFD) is a graphical representation that shows the flow of data within a system. It visually illustrates the processes, data storage, and data flow between different components of the system.

A DFD typically consists of four elements: processes, data stores, data flows, and external entities. Processes represent the functions or activities that manipulate data. Data stores represent where the data is stored within the system. Data flows represent the movement of data between the processes and data stores. External entities depict external sources or destinations of data.

Based on the information provided, the following data flow diagram can be created:

In this diagram, the client is represented as an external entity. The client sends post trade messages and orders to Fidessa via the FIX 4.2 protocol. These messages and orders are received by Fidessa OMS, which performs pre-trade compliance checks. The results of the compliance checks are sent back to the client.

The post trade information is sent back to the client in two ways. Firstly, a batch file is triggered at the end of the day, which is placed on the Internet facing SFTP server managed by Fidessa. Secondly, real-time post trade messages are sent to Fidessa hosted middleware. The results are then sent to the client’s database via a Fidessa installed service in the client’s datacenter.

The connection between Fidessa and the client is established over a private circuit managed by Fidessa. This private circuit ensures secure and reliable communication between the two entities.

In conclusion, the data flow diagram illustrates the flow of data within the proposed project scenario. It provides a clear visualization of how post trade messages and orders are exchanged between the client and Fidessa, as well as how the compliance results and post trade information are transmitted back to the client.
