Database Retrieval Glossary
A label is the identification tag associated with a time series.
These tags are defined in the CITIBASE Data
Dictionary. For example,
A label list is an enumeration of individual labels for simultaneous
retrieval. Lists are always surrounded by round parentheses, and list
elements are separated by commas. For example, a label list could
simply be an enumeration of labels as in
CITIBASE contains monthly, quarterly, and annual data. The following DATE formats are supported:
Data can be retrieved in different formats that are suited for viewing, printing, and exporting to various statistical packages. The following formats are available:
The original listings of series titles, as provided on distribution tapes, are almost entirely composed of abbreviations. Moreover, those abbrevations are used in a very inconsistent manner, resulting in the same word being rendered in a number of ways. Although for plain listings of series this may be merely annoying, but not fatal, a data dictionary with 80% of words being abbreviated in an inconsistent fashion is useless for keyword searches. We have, therefore, implemented filters which expand all abbreviations in the original series titles into full words. Well - almost all. Some abbreviations may have slipped through, a few were difficult to decipher, but - all in all - the "expanded" data dictionary is much cleaner, much more meaningful to view, and can be used for keyword searches. The original abbreviated series titles can still be viewed when series are accessed by clicking on their labels, and when retrieving data.
When searching the data dictionary by keyword(s), only the expanded version of the dictionary is used, since the original one would probably not render any results of such keyword searches.
