Structured Query Language
SQL (Structured Query Language) is a computer language aimed to store, manipulate, and retrieve data stored in relational databases. The first incarnation of SQL appeared in 1974, when a group in IBM developed the first prototype of a relational database. The first commercial relational database was released by Relational Software (later becoming Oracle).

This is Part 3 of a four-part article series on SQL Server Reporting Services 2005 (SSRS). Part 1 provided a step-by-step guide to basic report creation and Part 2 took a tour of some of the core SSRS features and functions that you'll need to develop dynamic reports. Here, we turn our attention to the chart control that ships with SSRS.

In Part 1 of this article, we looked at the basics of SQL Server Reporting Services 2005 (SSRS). We built one report with the Report Wizard, and one report using the Report Designer. In Part 2, we are going to look in more depth at the features that you can use everyday as an SSRS developer.

Building and deploying basic reports
If ever there was job for "real" developers to shuffle to their juniors, it is building reports. It's not real development anyway; it's more like glorified formatting.

Have you heard this statement or others like it? This is usually delivered early in a development cycle when someone, probably not the person spewing these words of "wisdom," suggests that performance should be taken into account when designing and building the database, or laying out the new server configuration, or writing a trigger.

XML has become the accepted way for applications to exchange information. It is an open standard that can be used on all technical platforms and it now underlies a great deal of the inter-process communication in multi-tiered and distributed architectures.

SQL(STRUCTURED QUERY LANGUAGE)
* SQL is a Non-procedural Language.
* SQL provides a fixed set of datatypes you cannot define new datatypes.
* Every SQL statement is terminated by a semicolon.
* An SQL statement can be entered on one line or split across several lines for clarity.
{mos_sb_discuss:29} SQL Server has three types of indexes—clustered, nonclustered, and primary and secondary XML indexes as XML and XML indexes are quite an advanced topic. The index type refers to the way the index and the physical rows of data are stored internally by SQL Server. The differences between the index types are important to understand.
Before it is possible to insert data using T-SQL code, you need to be familiar with the INSERTcommand and its structure.
The INSERT command is very simple and straightforward in its most minimal form, which is all that is required to insert a record.
