How not to
get lost in
“data” jungle?
Aylin ŞEN
What you
need?
Bulletproof
business
analysis.
How?
Data migration is typically the
most forgotten or
underestimated component of
an IT Project.
So, do you need a data migration?
You may have…
Requirements mention from the systems need to be shut down?
Requirements mention from entities that are already used in your
company’s systems? An application replacement Project?
Be careful.
Data migration is on its way!
Identify data sources.
Determine the master data and the
fate of other systems’ data.
Know how and where data is stored, backed up, and if
it is archived.
A must have activity: Data Profiling. Classify data.
Results of the profiling will guide you to design user interfaces and capture business rules.
Do you
need data
cleansing
?
Understand the data
structure.
Fate of the historical data
Fate of the missing or dirty data
Fate of the legacy data
?
Map entities
correctly in
details.
That’s how you
move data
successfully.
UI validations?
Define entity specs based on the
data profiling results.
If entities are not matching neatly,
you will need UI standards and
validation rules accordingly.
Rules for the gap btw
requiered result and
data pattern you have
will be your essentials.
New processes is
needed?
You may need to create new
processes to correct
problematic data or to
trigger different actions.
Define security & security measures.
Define migration acceptance criteria(s).
Plan the future.
Plan in details. Answers will guide you.
Do
rehearsals!
Better test than be surprized later! Migration has its own requirements to be tested.
