End Points in Sql Server

A SQL Server endpoint is the point of entry into SQL Server, or a way to connect to SQL Server instance.

Endpoints in SQL Server are similar to Web Services that expose database access over HTTP.
There are 5 system endpoints that are automatically created and that can’t be dropped (you can only start or stop them), one for each protocol

• TCP/IP
• Shared Memory
• Named Pipe
• VIA
• One endpoint for the dedicated administrator connection (DAC).

Page.IsValid and Page.Validate in Asp.net

After validating we may thing that we have built a secure application but a hacker could disable JavaScript and bypass all our validators ! This is where the Page.Validate() method and more importantly, the Page.IsValid property come in.

Page.IsValid is a property to check whether page validation succeeded or not

The Page.Validate() method is fired automatically by controls that have the CausesValidation property set to true. Note that the Button control’s CausesValidation property is true by default.

We should check this property only after calling the Page. Validate () method, or set the CausesValidation property to true which is by default true for button control.

Example :

protected void btnLogin_Click(object sender, EventArgs e)
{
    Page.Validate(); //optional here because it is required only if buttons's  CausesValidation property is set to false but it is true by default

    if (!Page.IsValid)
    {
        return;
    }     
    //write your login code here
}

DATA WAREHOUSING & DATA MINING

Data mining is due to the wide availability of huge amounts of data and the approach need for turning such data into useful information and knowledge. The information and knowledge gained can be used for applications ranging from market analysis, fraud detection, and customer retention, to production control and science exploration.Data mining can be viewed as a result of the natural evolution of information technology. The database system in the development of the following functionalities: data collection and database creation, data management (including data storage and retrieval, and database transaction processing), and advanced data analysis (involving data warehousing and data mining).
