Thomas Boutell and numerous developers have created a graphic software library known as the GD Graphics library for dynamic graphical computing. GD provides support for many programming languages such as C, Perl, Python, PHP, OCaml, and so on. In addition to generating HTML output, you can use PHP to create and compute graphics files in a number of graphic file formats such as PNG, JPEG, GIF, WBMP, and xpm. Also, the use of PHP allows you to output image streams directly to a browser. To do this

Stored ProceduresStored procedures exist in any relational database, such as Microsoft's SQL Server. A stored procedure is some code that is contained in a database, usually performing some operations on the data, which can improve performance for data-intensive computations and perform some business logic. When you use data, sometimes you get them through stored procedures.In this chapter, we explore some of the areas that EF needs to focus on when using stored procedures. We also use stored pr
