Optimum data quality
is ensured only when the data have undergone data cleansing. The quality of
data is defined by the correctness and usefulness of the data. Data
validation service providers use check routines that check whether –
- The input data is correct or not
- The data provided is of any use or not
- The data provided is secure or not
BDS Services being an
expert in the process of Data Validation services,
provide well-defined and consistent Data. Science and technology made the
process of data validation a lot easier. There are numerous ways that can be
used to validate whether the data entered is worthy of calling as a potential
lead or not. Some of the methods or common data validation rules used by our
star team are:
· Data type validation
Here, we use the
Validation check and Post-Check action. We send feedback to help enforce the
validation of the data. This also helps in checking whether the data entered is
consistent or not. Asking to review the data when entered is what should be
done.
· Simple constraint and range validation
We perform simple
tests to check whether the data entered is correct or not. Like checking
whether the US phone number entered for a particular state has the right code
or not. Suppose a company has 3 branches and the option is asking the person to
state the number code of their branch. If he/she fills it with a number that is
not a code of any of the branches, then the data is termed as invalid and is
not further processed.
· Cross-reference validation
We use external
resources to verify whether the data provided to us is valid or not. We check
the data by comparing it with the data we already have and also check with the
help of trusted databases.
· Structured validation
We implement
conditional constraints that further validate the data when we come across a
complex data set. Structured data validation is used for companies that depend
on complex data parameters like the finance industry.
Data validation is a process that must be done even if
the data is complex and huge. And it should also be verified by a human at a
certain point so as to make sure no good data is lost.
BDS Services offers Data Validation services along with Data mining, Web research, etc. To know
