Query: High speed data retrieval from national data center (ndc) reducing time
  and ignoring spelling error in search key based on double metaphone algorithm   Fast and efficient data management is one of the demanding technologies of
todays aspect. This paper proposes a system which makes the working procedures
of present manual system of storing and retrieving huge citizens information of
Bangladesh automated and increases its effectiveness. The implemented search
methodology is user friendly and efficient enough for high speed data retrieval
ignoring spelling error in the input keywords used for searching a particular
citizen. The main concern in this research is minimizing the total searching
time for a given keyword. This can be done if we can pre-establish the idea of
getting the data belonging to the searching keyword. The primary and secondary
key-code generated by the Double Metaphone Algorithm for each word is used to
establish that idea about the word. This algorithm is used for creating the map
of the original database, through which the keyword is matched against the
data.
