Question two also says.. :
Discuss features and application of the following database management systems.. :
a.PostgreSQL
e.Informix

Question Three.. :
Discuss and compare the following database management system in terms of security, reliablility, and GUI tools:
a.Oracle
b.sybase
c.DB2

I have a need to create a procedure and use a select at the same time(don’t ask why).

I’m use RazorSQL to interface with my Informix DB.

SELECT name FROM users WHERE id = 3 AND 1 = (CREATE PROCEDURE createtxt2() SYSTEM ‘echo damn > superman.php’; END PROCEDURE;);

This gives me a Syntax Error. However:
SELECT name FROM users WHERE id = 3; superman.php’; END PROCEDURE; <– works fine

Is there a way to put them both together in 1 sql query?

Thanks in advance.

The goal of this study is to discuss the different issues involved in operating system design, the different strategies that have been tried and to provide concrete examples where possible. Given the number of open-source operating systems available, specific implementations will be used as examples where possible.

Example Operating Systems

Naturally, open source operating systems lend themselves to teaching more than proprietary operating systems. The source code of all the following operating systems is available free of charge online:
Linux
Net/Free/OpenBSD
Solaris
MINIX
GNU Hurd
XOK
ReactOS

While the following operating systems are closed source, enough is known about their implementation that they can all be used as specific examples of approaches to various OS design issues and tasks.
Mac OS X
Microsoft Windows 9x
Windows NT
QNX
DOS
HP-UX
AIX
BeOS

Example filesystems
FAT
NTFS
ext4

Case Study Areas

The following areas of operating system design can all be illustrated with specific examples from real operating systems. In some cases different approaches to the same task can be seen within one OS. For example, many operating systems support multiple file system types.
Loading the operating system
Initialising the operating system for use
Managing tasks (processes)
Managing memory
File systems and storage management
User interfaces

For example, in the “Managing tasks” section we might use the example of task management in a single tasking operating system like DOS, as well as some of the different scheduling algorithms that have been used in various multitasking operating systems.

The case study can include comparative analysis about any concept of different operating systems or comparison between the different versions of same operating systems. It can include the total functionality of the operating system given.
