Data sources provide the raw data made available for analysis within DAP.LIVE. Data is gathered from a wide and ever increasing number of sources many of which are freely available and some of which are obtained from commercial providers. DAP.LIVE also implements a number of unique data sources where possible to reduce overheads and restrictions in passing on data to our users.
Data sources are either made available to DAP.LIVE in bulk or via real time lookups (see Architecture Overview for a detailed explanation of these two types) and the DAP.LIVE system is designed to work well with both types of source in an integrated manner.
The section below contains the current list of implemented Data Sources with information about the type of data source and basis (commercial or free) upon which the data is made available.
