Data is crucial for every organization. Managing and storing data is becoming critical to every organization. Data capture, Data entry, merging/compilation of data, sorting of data, editing of data and data validation are different processes in a data cycle.

Data Cycle

2. The Data Cycle
Data is very important to the organization and is
at the heart of every organization
Managing and storing enterprise data is fast
becoming one of the most Critical IT
challenges
The types of processing which may undergo
through life cycle are :
Data capture:
The capturing of data is a necessary initial step
preceding other activities in data processing
The data collection is done as per the
requirement of the organization

3. The Data Cycle
Data Entry:
Data entry is the process of converting raw data to the
Digital form by physically entering or Scanning
Merging /Compilation of Data
After the required data has been acquired, it has to be
Merged, and Compiled as per the organization’s
requirements
Sorting of Data:
The Logical sequence of the data depends upon the
purpose of the information required . The sequencing of
data needed for the output of information is known as
sorting
……..cont

4. The Data Cycle
The ‘order by’ clause is used by the modern databases to
sort the data on the desired sequence
The DBMS does the sorting on the Fly before presenting
the data to user or programmer which requested data in
that order
Editing of data:
The editing or make changes in the data already entered of
the data is undertaken to correct the data
Data validation:
Data validation is the testing of input data records to
determine if they are correct and complete .this cannot
be done with complete assurance but reasonable
assurance is always possible

5. The Data Cycle
Storage:
The process of data storage enables the
reduction in cost and improvement in the
data management
Online storage is very expensive for the
organizations
Very old data is usually stored and kept for
Statutory requirements by almost all
organizations.
Current data is stored as backup
Data is stored in secondary devices such ad
hard disk,CDs,floppies ,Pen drive

6. The Data Cycle
Data Access/Sharing:
Data items are of value only if they can be retrieved,
accessed and presented to those who need them for
decision or action to which they apply.
The Data stored should be accessible to all the users.
DBMS make this access possible and safe
Upgrading of data:
The items in the data have to be upgraded to reflect the
most current information,Upgrading is done on continual
basis

7. The Data Cycle
Data Archives
The form of storing very old data is known as
Archival
The ideal archiving solution must guarantee to
retain the referential integrity and business
context of the archived data
Disposal of data:
Over time data looses its validity & is accessed
less often.gradually loosing business value &
finally ending with its disposal
