QUSMA Data Management System (QDMS)
The QUSMA Data Management System (QDMS) is a client/server system for acquiring, managing, and distributing low-frequency historical and real-time data, written in C#.
The server acts as a broker between clients and external data sources, as well as a local database of historical data. The server UI allows its use without the need for a client application.
Here's a rough view of how the systems are connected to each other:
A client library is provided which can access the server either locally or over a network, to request data, metadata, etc. A simple sample application showing usage of the client can be found here.
QDMS uses MySQL or SQL Server for storage, ZeroMQ and Protocol Buffers for client/server communications and MahApps.Metro for the interface.
- Manage metadata on stocks, options, futures, CFDs, etc.
- Download historical and real time data from external data sources.
- Local storage of historical data.
