Integrating data from multiple databases or systems can present several challenges.
00:33
One, data inconsistency.
00:41
Different databases may have different formats, structures, or standards for their data.
00:46
For example, one database might store dates in a month -month, date -date, year -year year -year format.
00:52
So two -digit month, two -digit date, and four -digit year.
00:55
While another could use the four -digit year first, then the two -digit month, and then the two -digit day.
01:00
This inconsistency can make it difficult to merge data.
01:04
Two, data quality.
01:11
The accuracy and completeness of data can vary between systems.
01:15
Some databases might have missing or incorrect data, which can affect the quality of the integrated data.
01:22
Three, data duplication...
