...9.3 Reserved Words Certain words such as SELECT, DELETE, or BIGINT are reserved and require special treatment for use as identifiers such as table and column names. This may also be true for the names of built-in functions. Reserved words are permitted as identifiers if you quote them as described in Section 9.2, “Schema Object Names”: mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax ... near 'interval (begin INT, end INT)' mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec) Exception: A word that follows a period in a qualified name must be an identifier, so it need not be quoted even if it is reserved: mysql> CREATE TABLE mydb.interval (begin INT, end INT); Query OK, 0 rows affected (0.01 sec) Names of built-in functions are permitted as identifiers but may require care to be used as such. For example,COUNT is acceptable as a column name. However, by default, no whitespace is permitted in function invocations between the function name and the following “(” character. This requirement enables the parser to distinguish whether the name is used in a function call or in nonfunction context. For further detail on recognition of function names, see Section 9.2.4, “Function Name Parsing and Resolution”. The words in the following table are explicitly reserved in MySQL 5.6. In addition, _FILENAME is reserved. At some point, you might upgrade to a higher version, so it is a...

Integrative Network Design Project

...Integrative Network Design Project II Communications protocols are where the rubber meets the road when discussing communications between computers. These protocols set the parameters for computer communication and allow them to communicate in an organized manner. Without protocols a network would be worthless and very ineffective. The protocols help not only in preventing errors but they also provide a way of tracking down errors by giving the user a systematic process to check for possible repairs. Some of the main things protocols do are: 1. Provide private communication capabilities. 2. Give users the ability to authenticate traffic. 3. Organizes packets (Packets are data organized in a specific format containing user information/ handling instructions). 4. Provide a way to pinpoint errors in communication. The proposed changes to the system are based on the technical vulnerabilities caused by using hardware/software and wiring that is old or not optimal. The current protocols used are acceptable but need to be overhauled in order to provide Kudler with faster communication over long distance. Uniformity of the network is obvious in the current Ethernet network set up built over T3 100 base connections and the versatility of the Novell 4.11 server is a plus; but the Novell uses an Internet Package Exchange/Sequence Package protocol (IPX/SPX). This protocol is generally supported but not globally supported like TCP/IP. The IPX/SPX protocol works great with......

Given today’s pressing need to optimize IT services and resources while reducing costs and improving organizationwide productivity, the Cisco lifecycle methodology offers the framework needed to make operations more efficient and responsive.

This case study describes Cisco IT’s internal infrastructure, a leading-edge enterprise IT environment that is among the largest and most complex in the world. “By moving from a traditional technology, silo-based organizational structure to a lifecycle-based model, we were able to improve our operational metrics considerably. Our number of cases decreased by approximately 60 percent, and our time-to-repair to get clients back up and running has decreased by almost 70 percent.” John Manville, Vice President, IT Network and Data Center Services, Cisco BACKGROUND An enterprise with 300 locations in 90 countries, Cisco has 46 data centers and server rooms supporting the 65,000-plus employees.
