When you’re in a Data profiling job, you will always hear some clients asking for something like this,
“Can you produce 200 records daily?”
“I’m looking for 4000 record list that only consist of… The specs are in the email I sent to you”
Well, it isn’t that hard of a job when you don’t really have a deadline to catch, but when the deadline is only within a day or two. Then this job will need everyone in your team to work hand in hand.
Data profiling isn’t what I could say a “Piece of a cake” kind of job. Although we have some guidelines to follow, we seldom do it by what we know and that is, Double check some data’s and correct some.
Understanding how profiling works.
Understanding how profiling works is one thing that every customer or client need to know. Why? Because customers or clients need to be fully aware that some of the missing data can’t be found or some of their specifications aren’t that free or searchable.
Some data’s like personal emails or mobile number are personal, so it is set in private by that person. Data profiling doesn’t only depend on LinkedIn, Facebook or twitter to gather data from people within the list. It usually depends on the person who is working and this is why data profiling takes a lot of time.
It depends on how a person does its job on the given list.
When a prospect or client gives out its specification, it is given to two to three persons. This means that on every data profiling project, two or three people are working on it. And once the list is done, the team leader or the one who assigns to finalize everything will double check the list, to avoid duplicates or fill out what is missing.
Data profiling requires a lot of time and accurate research, but more importantly, it requires personnel that is good at finding information that can’t be research by its fellow profiler.
