What is a fuzzy date?
Answer: Fuzzy dates are less than complete dates. Use fuzzy dates when you are unsure of a complete date. For example, if you do not know the day and month a constituent was born, but you do know the year, you can enter only the year in the Birth date field of the constituent record.
Which data type is used to store Data and time?
Date data type is used to store date and time values .
What is the standard format of date data type?
This includes: (1) the standard format for dates and times (YYYY-MM-DD HH:MM:SS:mmm, with the time in 24-hour format); (2) MM/DD/YYYY, the format used in the database; (3) the default formats set up by Eloqua (as long as they are not modified or deleted by the Customer Administrator); or (4) any of the additional …
How to store date and time in a database?
To store information in a database, I would use a char column-type to store the whole America/Santiago timezone identifier and another char column-type to store the date/time (in the yyyy-mm-dd hh:ii:ss format). Alternatively, you can pick a ‘datetime’ column-type, as long as that type ignores timezones altogether.
How to do fuzzy search in big data?
Fuzzy search in big data is also known as approximate nearest neighbors. This library offers you different metric, e.g Euclidian, Hamming and different methods of clustering: LSH or k-means for instance. The search is always in 2 phases.
Can you sort by Timezone in a database?
Databases rarely handle timezones, daylight savings time and rule changes correctly, so avoid the database specific functionality all together. Using either a char or a timezone-less ‘datetime’ column-type would still allow you to sort and by using a ‘datetime’ column-type you can even do calculations.
How to convert fuzzy matching to exact search?
The problem then becomes how to convert your fuzzy matching to exact search. A common approach is to use locality-sensitive hashing(LSH) with a smart hashing method, but as you can see in your two examples, sometimes you can get away with even simpler approach.
