HTML Control Vs. ASP.Net Control

HTML Controls	ASP.Net Controls
HTML control runs at client side.	ASP.Net controls run at server side.
You can run HTML controls at server side by adding attribute runat=”server”.	You can not run ASP.Net Controls on client side as these controls have this attribute runat=”server” by default.
HTML controls are client side controls, so it does not provide STATE management.	ASP.Net Controls are Server side controls, provides STATE management.
HTML control does not require rendering	ASP.Net controls require rendering.
As HTML controls runs on client side, execution is fast.	As ASP.Net controls run on server side, execution is slow.
HTML controls do not have any separate class for its controls.	ASP.Net controls have separate class for its each control.
HTML controls does not support Object Oriented paradigm.	With ASP.Net controls, you have full support of Object oriented paradigm
HTML controls can not be accessed form code behind files.	ASP.Net controls can be directly worked and accessed from code behind files.
HTML control have limited set of properties and/or methods.	ASP.Net controls have rich set of properties and/or methods.
Enter Name : < input type="text"  ID="txtName" >	Enter Name :  <asp:TextBox Id="txtName" runat="server”>

Comparison of Oracle & SQL Server Management Tools

 What is the main tool to administer the database?
SQL Server -The main tool is SQL Server Management Studio.

Google's abc.xyz

One giant winner in Google's rebranding announcement: Daniel Negari.
Negari is the founder and CEO of XYZ.com, an Internet domain registry that owns alternative suffixes like .rent and .college. His 10-person company also owns .xyz.
Abc.xyz is the web address for Google's new parent entity, Alphabet Inc.

Google announced on Monday a dramatic restructuring that breaks out the Web giant's core business into a separate company under a new umbrella called Alphabet. Other companies that will be part of Alphabet are the life sciences unit and Calico, which is focused on longevity.

Larry Page, co-founder and CEO of Google, will assume the CEO role of Alphabet, with Google co-founder Sergey Brin serving as president. Sundar Pichai, head of product and engineering, is now CEO of Google. Alphabet is replacing Google as the publicly-traded entity.
Currently, abc.xyz is just a landing page, with a letter from Page explaining the changes and some blocks with letters

"It's a big deal for new top-level domains as a whole," said Negari, who has operations in Santa Monica, California, and Las Vegas. "It's a big signal that Google, which is the largest search engine in the world, believes in it enough to switch to one."

New Features in ASP.NET 2015 | ASP.NET 5

Whenever you made any change in your project, you have to rebuild it to check its effects. But now in ASP.Net 2015,there is no need to rebuild it again, as it used Roslyn compiler for this.

    Earlier we need to do lot of configuration for publishing or deploying project in cloud, but now in ASP.NET 2015, you can easily migrate and deploy your project using cloud ready configuration. Tip for publishing project in cloud: first by converting your asp.net project to azure cloud project and then publish that converted azure project.

    In .Net 5, you can easily IIS host or self host, your asp.net 2015 project.

    Asp.net 2015 has open source in github, that means you can find code of asp.net 5 from github, and you can make repository of your project in github just live svn.

    ASP.NET uses 3 types of run time engine
        1. Full .Net CLR (Default)
        2. Core CLR (Include only those which is needed in your application for ex using system.console only)
        3. Cross Platform CLR (For running app on mac and linux os)

    In ASP.Net 2015 you can run new and old version code together. For this you have to use core CLR.

    No need to add assembly in references, you can directly add assembly name with version in project.json file. Intellisense will work for this.

    In ASP.Net 2015, you can easily use MVC, web api and web pages together without any conflicts of their features, as MVC 6 is introduced for this. So there is no need to write different code for all three technologies.

    ASP.NET 5 uses new http pipeline, which uses less overhead in pipeline and improves http performance.

    ASP.NET 5 can use dependency injection i.e. can replace module with another module without altering the client.

    ASP.NET 5 can run older version asp.net application without modification of any code except mvc6 and signal r 3, as they use new http pipeline.

Difference between c#.net & VB.net

Here are some key difference in C# and VB.NET other than syntax difference.

1. In C#, using keyword is used to release unmanaged resources. (Not available in VB.NET)
2. Optional parameter is supported in VB.NET. (Not available in C#).
3. Structure and unstructured error handling (On Error GoTo) is supported in VB.NET. (Unstructured error handling is not supported in C#).
4. Event gets bind automatically in VB.Net.
5. VB.NET is not case sensitive where C# is.
6. Shadowing: – This is a VB.Net Concept by which you can provide a new implementation for the base class member without overriding the member. You can shadow a base class member in the derived class by using the keyword “Shadows”. The method signature, access level and return type of the shadowed member can be completely different than the base class member.
   
   Hiding: – This is a C# Concept by which you can provide a new implementation for the base class member without overriding the member. You can hide a base class member in the derived class by using the keyword “new”. The method signature, access level and return type of the hidden member has to be same as the base class member. Comparing the two:- 1) The access level, signature and the return type can only be changed when you are shadowing with VB.NET. Hiding and overriding demands these parameters as same.
   2) The difference lies when you call the derived class object with a base class variable. In class of overriding although you assign a derived class object to base class variable it will call the derived class function. In case of shadowing or hiding the base class function will be called.
   
7. Visual Basic .NET can also force parameters to be passed by value, regardless of how they are declared, by enclosing the parameters in extra parentheses. There is no way to achieve this thing in C#.

OLTP Vs. OLAP

Online Transaction Processing

OLTP System deals with operational data. Operational data are those data  involved in the operation of a particular system.

Example: In a banking System, you withdraw amount from your account. Then Account Number, Withdrawal amount, Available Amount, Balance Amount, Transaction Number etc are operational data elementions.

    Operational Data
    Operational data are usually of local relevance
    Frequent Updates
    Normalized Tables
    Point Query

In an OLTP system data are frequently updated  and queried. So quick response to a request is highly expected. Since the OLTP systems invlove large number of update quiries, the database tables are optimized for write operations.

To prevent data redundancy and to prevent update anomalies the database tables are normalized.Set of tables that are normalized are fragmented.Normalization makes the write operation in the database tables more efficient.

Operational data are usually of local relevance.It involves Queries accessing individual tuple(individual record).These type of queries are termed as point queries.

Example :Bank account transaction

Online Analytical Processing (OLAP)

OLAP deals with Historical Data or Archival Data. Historical data are those data that are archived over a long period of time. Data from  OLTP are collected over a period of time and store it in a very large database called Data warehouse. The Data warehouses are highly optimized for read (SELECT) operation.

Example: If we collect last 10 years data about flight reservation, The data can give us many meaningful information such as the trends in reservation. This may give useful information like peak time of travel, what kinds of people are traveling in various classes (Economy/Business)etc.

Analytical Query: Online Analytical Processing (OLAP) quries are of  analytical form. Query need to access large amount of data and require huge number of aggregations. It access large number of records from database tables and perform the required operation based on this.

    Historical Data or Archival Data
    Infrequent updates
    Analytical queries require huge number of aggregations
    Integrated data set with a global relevance

Updates are very rare in a Data warehouse.OLAP quiries will give aggregated information about the things happend in the past over a period of time and this will help the management in strategic decision making. Hence OLAP Queries are of  having  significant importance in strategic decision making.

Example: profit changing over the years across different regions
