The Next process of normalization is convert the first normalization form 1NF to second normalization form 2NF. In this process we will remove any non-key attributes that only depend on path of the table key to a new table. Enen many data sources normalized after the 2NF but some time we need to proceed for the next step also. But in this article w will see only to convert the 1NF to 2NF.
As we have seen previously how to convert the data source to Un-Normalized Form also called UNF. Today we will proceed for the next step. In this step we transform the UNF into the first Normalization Form that is called 1NF. To accomplish this we need to remember a rule: we need to remove repeating attributes to a new table. here we will discuss the process to do this.
Recently we have discusses about normalization and the procedure to normalize the data source. Today we will discuss about for this process. As you know that the first step in normalization is to convert the data source to Unnormalized Form that is also called UNF. If you will follow the process accurately then there will be no errors in the first step of normalization.
As we check our coding page in .net application we found that at the top after the namespaces there is a call that is partially defined in every web page. The question arrives in our mind that what is this Partial and why we use the class with partial access specifier. Why we not use the class as publicly or privately? Here we are to answer all these question. First we will get the partial class definition and its need.
The Normalisation is a data analysis technique to design a database system. The Normalisation allows the database designer to understand the current data structure within an organisation. The end result of a normalisation is a set of entity. We remove the unnecessary redudency by normalising the database table. Read the rest of this entry »
The Alias name is the name that is referred to any column name or table name that is given by user. The alias name also used to represent some column or table without using its real name. As we will proceed in this article we will see that how we can use both the alias column name and alias table name in SQL Server.
Using the Querystring is the another method to pass information between pages in your ASP.NET application. As we know that Querystring is the portion of the URL after a Question Mark(?). The information is always retrieved as a string that can be converted with any type.Here we get the code to pass multiple values at a single time in Querystring.
