DBMS | Normalization: In this tutorial, we will learn about the normalization, different types of the normalization with the examples.
In this first example there are two rows for Heather, with changes to the second row to show the fact that there are multiple pets. While this is searchable, and follows first normal form, it is an inefficient use of space. To achieve second normal form, it would be helpful to split o...
In image processing, normalization isa process that changes the range of pixel intensity values. Applications include photographs with poor contrast due to glare, for example. ... Often, the motivation is to achieve consistency in dynamic range for a set of data, signals, or images to avoid me...
Normalization is the process of efficiently organizing data in a database. There are two goals of the normalization process: eliminating redundant data (for example, storing the same data in more than one table) and ensuringdata dependenciesmake sense (only storing related data in a table). Both...

Example: a shopping cart order Suppose that we are designing a schema for a shopping cart application. Our application stores orders in MongoDB, but what information should an order contain? Normalized schema A product: {"_id": productId,"name": name,"price": price,"desc": description ...
We see here in Student_Project relation that the prime key attributes are Stu_ID and Proj_ID. According to the rule, non-key attributes, i.e. Stu_Name and Proj_Name must be dependent upon both and not on any of the prime key attribute individually. But we find that Stu_Name can be...
In the example above, the other column headers are considered candidate keys. The attributes of those candidate keys that make them unique are calledprime attributes. Third normal form (3NF).At the second normal form, modifications are still possible because a change to one row in a table may...
