14 Rules for Faster-Loading Web Sites

• These rules are the key to speeding up your web pages. They've been tested on some of the most popular sites on the Internet and have successfully reduced the response times of those pages by 25-50%. The key insight behind these best practices is the realization that only 10-20% of the total end-user response time is spent getting the HTML document to the browser. You need to focus on the other 80-90% if you want to make your pages noticeably faster. These rules are the best practices for optimizing the way servers and browsers handle that 80-90% of the user experience.
   
• Rule 1 - Make Fewer HTTP Requests
• Rule 2 - Use a Content Delivery Network
• Rule 3 - Add an Expires Header
• Rule 4 - Gzip Components
• Rule 5 - Put Stylesheets at the Top
• Rule 6 - Put Scripts at the Bottom
• Rule 7 - Avoid CSS Expressions
• Rule 8 - Make JavaScript and CSS External
• Rule 9 - Reduce DNS Lookups
• Rule 10 - Minify JavaScript
• Rule 11 - Avoid Redirects
• Rule 12 - Remove Duplicate Scripts
• Rule 13 - Configure ETags
• Rule 14 - Make AJAX Cacheable

Difference between SQL Server 2008 and SQL Server 2012

S.No	SQL Server 2008	SQL Server 2012
1	Maximum number of  concurrent connections:  The Maximum number of concurrent connections to SQL Server 2008 is 32767.	Maximum number of  concurrent connections:   SQL server 2012 has unlimited concurrent connections.
2	Precision used for spatial calculations: The SQL Server 2008 uses 27 bit bit precision for spatial calculations.	Precision used for spatial calculations:  The SQL Server 2012 uses 48 bit precision for spatial calculations
3	TRY_CONVERT() and FORMAT() functions:   TRY_CONVERT() and FORMAT() functions are not available in SQL Server 2008	TRY_CONVERT() and FORMAT() functions:    TRY_CONVERT() and FORMAT() functions are newly included in SQL Server 2012
4	ORDER BY Clause with  OFFSET / FETCH options:  ORDER BY Clause does not have OFFSET / FETCH options as in SQL Server 2012	ORDER BY Clause with OFFSET / FETCH options:  ORDER BY Clause now have OFFSET / FETCH options to use paging to show required rows per page in applications and allow the user to scroll through each page of results rather than download the entire set In the sample query below, SQL Server would return 10 records beginning with record 11. The OFFSET command provides a starting point for the SELECT statement in terms of paging, and the FETCH command provides how many records to return at a time. SELECT BusinessEntityID, FirstName, LastName FROM Person.Person ORDER BY BusinessEntityID OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY;
5	Code Name:  SQL Server 2008 is code named as Katmai.	Code Name:  SQL Server 2012 is code named as Denali
	In SQL Server 2008, audit is an Enterprise-only feature. Only available in Enterprise, Evaluation, and Developer Edition.	In SQL Server 2012,support for server auditing is expanded to include all editions of SQL Server.
7	Sequence Object:  Sequence is not available in SQL Server 2008	Sequence Object:  Sequence is included in SQL Server 2012.Sequence is a user defined object that generates a sequence of a number. Here is an example using Sequence. /****** Create Sequence Object ******/ CREATE SEQUENCE MySequence START WITH 1 INCREMENT BY 1; /****** Create Temp Table ******/ DECLARE @Person TABLE ( ID int NOT NULL PRIMARY KEY, FullName nvarchar(100) NOT NULL ); /****** Insert Some Data ******/ INSERT @Person (ID, FullName) VALUES (NEXT VALUE FOR MySequence, 'Umar Ali'), (NEXT VALUE FOR MySequence, 'John Peter'), (NEXT VALUE FOR MySequence, 'Mohamed Iqbal'); /****** Show the Data ******/ SELECT * FROM @Person; The results would look like this: ID FullName 1 Umar Ali 2 John Peter 3 Mohamed Iqbal
8	Full Text Search Capability:  The Full Text Search in SQL Server 2008 does not allow us to search and index data stored in extended properties or metadata.	Full Text Search Capability:  The Full Text Search in SQL Server 2012 has been enhanced by allowing us to search and index data stored in extended properties or metadata. Consider a PDF document that has "properties" filled in like Name, Type, Folder path, Size, Date Created, etc. In the newest release of SQL Server, this data could be indexes and searched along with the data in the document itself. The data does have to be exposed to work, but it's possible now.
9	BISM Model:  Analysis Services in SQL Server does not have BI Semantic Model (BISM) concept.	BISM Model:   Analysis Services will include a new BI Semantic Model (BISM). BISM is a 3-layer model that includes: Data Model Business Logic Data Access BISM will enhance Microsoft's front end analysis experiencing including Excel, Reporting Services and SharePoint Insights. Microsoft has said that BISM is not a replacement for the current BI Models but more of an alternative model. In simple terms, BISM is a relation model that includes BI artifact such as KPIs and hierarchies.

LIKE (Transact-SQL) Sql Server

Wildcard character	Description	Example
%	Any string of zero or more characters.	WHERE title LIKE '%computer%' finds all book titles with the word 'computer' anywhere in the book title.
_ (underscore)	Any single character.	WHERE au_fname LIKE '_ean' finds all four-letter first names that end with ean (Dean, Sean, and so on).

WHERE au_lname LIKE '[C-P]arsen' finds author last names ending with arsen and starting with any single character between C and P, for example Carsen, Larsen, Karsen, and so on. In range searches, the characters included in the range may vary depending on the sorting rules of the collation.
[^]	Any single character not within the specified range ([^a-f]) or set ([^abcdef]).	WHERE au_lname LIKE 'de[^l]%' all author last names starting with de and where the following letter is not l.
