Data Management Layer

The data management layer consists of those elements that relate to the entry, storage and maintenance of the archival information. The entry interface streamlines the process of data entry and is designed to meet the needs of the onsite Project researchers while protecting the quality of the data. (See: Data Entry Interface) In December, 1998, the backend structure was separated from the front-end elements to provide total independence in refining the front-end and performing management tasks without affecting the back-end structure or ongoing entry.

1. Data input controls: custom-designed screens maintain quality control during data entry. Within the database, vocabulary is rigorously controlled by way of standard database integrity checks, including predefined lists, context-driven help screens and programmed data entry procedures. All data is entered into the database directly from the documents via the keyboard or drop-down lists. This data includes transcribed document citations, document dating, names and locations of senders and recipients, document extracts, English synopses, People, Places and Topics indexing.
   
   
2. Data retrieval tools: data retrieval mechanisms (search, filter, sort, and query) assist in the process of indexing and data entry. For example, when working on data entry for a given document, the researcher can quickly collect and view all indexed documents pertaining to a given sender/recipient, place, topic or combination of fields, in order to facilitate identification and categorization. Since a database is only as useful as its data is reliable, data entry and management procedures have been a top priority.
