Microsoft SQL Server 2008 Programming.
This is book is mainly about the usage and programming using Microsoft SQL Server 2008 , how to do database setup , inserting , updating , deleting tables and so on…I borrowed it from the National Library (PNM). It teaches us the basic syntax of using Microsoft SQL Server 2008 programming language. Databases are made up of many things , but none is more central to the make-up of a database than tables are. A table can be thought of as equating to an accountant’s ledger or an Excel spreadsheet. It is made up of what is called domain data (columns) and entity data (rows). The actual data for the database is stored in the tables.
SQL Server is a large product and the various pieces of it utilize a host of services that run in the background on your server. A full installation will encompass nine different services , and seven of these can be managed from this part of the SQL Server Configuration Manager ( the other two are services that act as background support ).
SQL Server provides several of what are referred to as Net-Libraries (network libraries) , or NetLibs. These are dynamic-link libraries (DLLs) that SQL Server uses to communicate with certain network protocols. NetLibs serve as something of an insulator between your client application and the network protocol , which is essentially the language that one network card uses to talk to another , that is to be used. They serve the same function at the server end , too. The NetLibs supplied with SQL Server 2008 include Named Pipes , TCP/IP (the default) , Shared Memory and VIA ( a special virtual interface that your storage-hardware vendor may support ).
Every time you run a query , SQL Server parses your query into its component parts and then sends it to the query optimizer. The query optimizer is the part of SQL Server that figures out the best way to run your query to balance fast results with minimum impact to other users . When you use the Show Estimated Execution Plan option , you receive a graphical representation and additional information about how SQL Server plans to run your query. Similarly , you can tun on the Include Actual Execution Plan option. Most of the time , this will be the same as the estimated execution plan , but you will occasionally see differences here due to changes that the optimizer decides to make while running the query , as well as changes in the actual cost of running the query versus what the optimizer thinks is going to happen.

Cascading Style Sheets – Separating Content From Presentation
This book i borrowed from the National Library (PNM). It tell us about how to use the Cascading Style Sheets , the origin of it , the foundation and concepts , the XHTML and CSS. CSS at its core is extremely simple and powerful. It allows you to attach style rules to HTML markup elements , such as the <p> or <a> element. These rules define the presentational aspects of the HTML elements to which they apply, such as color or typeface.
The popularity and power of a general-purpose SGML document type such as HTML wasn’t lost on XML’s designers , however , and as a transitional step toward the future , the HTML vocabulary wan reimplemented in XML as XHTML , the basis of most of our examples in this book. By making use of a well-known and proven generic document type , XML’s creators hope to leverage the knowledge of millions of web author while tightening down the screws with regard to syntax. As a result , a valid XHTML document may be viewd in any modern browser ( and even in most legacy browsers ) without much difficulty , and it may also be used by tools designed to interpret and manage XML documents , because it is itself an application of XML. Eventually , the Web’s architects expect that we’ll all be suing XHTML with our own , or with widely adopted , XML formats such as SVG , MathML , RDF , RSS , and others.
