Normalization
• Normalization is the process of simplifying the relationship between data
elements in a record[12]
• Database normalization is the process of organizing the fields and tables of
a relational database to minimize redundancy and dependency.
Normalization usually involves dividing large tables into smaller (and less
redundant) tables and defining relationships between them[13]
• normalization is the process of organizing it into tables in such a way that
the results of using the database are always unambiguous and as intended.
Normalization

•
1) Avoids data modification (INSERT/DELETE/UPDATE) anomalies as each data item lives in One place
2) Greater flexibility in getting the expected data in atomic granular
3) Normalization is conceptually cleaner and easier to maintain and change as your needs change
4) Fewer null values and less opportunity for inconsistency
5) A better handle on database security
6) Increased storage efficiency
7) The normalization process helps maximize the use of clustered indexes, which is the most powerful and
useful type of index available. As more data is separated into multiple
tables because of normalization, the more clustered indexes become available to help
speed up data access.[15]
Conclusion
• the concept of controlling electric devices on Customer Side System based
on the behavior in Smart home that had two sources for power both
Renewable Energy and General Utility. Two main points considering for this
are the way to manage storage battery unit and data management of CS by
using normalization however in long term relationship between customer
activity and Utility system service will get more benefit for each other
( reduce the consumption at peak hour etc.).
