External Database
The Enterprise Repository External Database acts as a central location for data storage and presentation to Sakai. As such, it needs to collect information from a variety of sources, and present that information in a manner amenable to the Sakai provider mechanism.
Requirements
- Support for Varied Source Data Sourcingframeworks: The data being provided to the Enterprise Repository External Database can come from a number of different sources. The Repository must be able to handle most, if not all, sources of data.
- Freshness of Data: In some cases, the data being provided to Sakai must be as close to the current state of the data source as possible.
- Query Execution Speed: Given that the repository generally aggregates data from external sources, the speed by which aggregated data is provided to Sakai must be optimized.
- Synthesis of Heterogeneous Data: In some cases, multiple data sources may contain similar versions of source data. Care must be taken when synthesizing this data for presentation to Sakai.
Achitectural Design
The Enterprise Repository External Database will be hosted on a single database server. This database will, at one end, allow data to be fed into it from various source systems on campus, and at the other end will provide a database schema readable by Sakai, and formatted to be as efficient as possible in the Sakai structure.
