The update time for Big Data depends on different data types and sources. Some data will be updated daily, while others may take a week or more to update. This depends on the size of the data volume and the complexity of the data collection and processing. If you need to use a particular piece of data, it's a good idea to know where it comes from and how often it's updated.

Additionally, if you have been rejected for a loan, it is recommended that you check your creditworthiness first through Credit Check. If you have poor credit, it's better to wait until your credit risk score is lowered and the blemish is removed before attempting to apply for a loan, as you'll have a better chance of passing.
