Sql Performance
SQL, which is short for Structured Query Language, stands at the heart of database development. It is the programming language used most often by database application developers, for modifying or obtaining information from a relational database. Thus, it logically follows that, to keep your database operating in tip top condition, you must first optimize the performance of your SQL statements.
Of course the most obvious way to gauge the performance of a SQL statement is to measure the amount of time it takes to execute. In determining this value the developer or database administrator needs to examine how long it takes to process hardware to return query results. This includes the CPU and the various I/O devices.
In addition to measuring the time it takes to process the SQL statements,[url=http://www.holisteroutlet.cc]hollister france[/url], an evaluation of SQL performance should also include a calculation of how much of the system resources are being consumed during the operation. This is especially true for I/O devices. The developer could make use of some built in SQL server commands, such as GETDATE() or SET STATISTICS. The developer might also consider purchasing one of the prepackaged SQL performance monitor products offered by several third party software vendors.

Grand National Party presidential candidate Lee Myung-bak speaks at his party's supreme leadership committee meeting on Monday. National Tax Service Commissioner Jeon Goon-pyo on Monday admitted that his office repeatedly investigated the assets of Grand National Party presidential candidate Lee Myung-bak and his relatives between 2001 and July this year. ��We reviewed the assets of some 12 people and related corporations 79 times through the Tax Integrated System,�� Jeon said. He claimed the reviews were part of the NTS�� ��routine duties." Jeon made the remarks when seven GNP lawmakers from a special party committee set up to fight off political maneuvers visited him.
Jeon said the ��reviews�� included Lee, his family, his brothers,[link widoczny dla zalogowanych], relatives including his brother-in-law Kim Jae-jung,[link widoczny dla zalogowanych], and related corporations. But he revealed no details of how many times each individual's assets were examined and when the reviews were conducted. Asked if there was a political motive to the reviews,[link widoczny dla zalogowanych], Jeon said,[link widoczny dla zalogowanych], "We began reviews because candidate Lee and his family run many corporations and were involved in many purchases and transfers of property. At one time, some of them were reviewed as part of our office's sweeping investigation of owners of more than three homes."
Asked when the reviews were done, Jeon said, "In May last year, the press began reporting suspicions involving Lee's assets. By August and September last year, the press had mentioned dozens of such suspected cases.�� He said most reviews were ��naturally�� conducted during this period. ��The press carried stories with apparent focus on (Lee��s) suspected evasion of taxes. Our office just reviewed his records online,[link widoczny dla zalogowanych], so there was no problem."
The Tax Integrated System makes it possible to search everything including ownership of real estate and other assets, income, overseas travel records, overseas money transfers and major stock holdings by typing in the subject's residence or business registration number. The information is used as verification to determine whether to start a proper tax probe if reports of irregularities are made.
Lee Myung-bak in a party meeting the same day said government agencies including the NTS ��are doing many things based on their plans to prolong the life of those in power,[link widoczny dla zalogowanych].�� He said some government officials ��may have unwillingly taken part in such things because their arms were twisted by those in power,[link widoczny dla zalogowanych]." GNP Floor Leader Ahn Sang-soo said the National Intelligence Service's clandestine investigation of Lee coincided with the NTS's behind-closed-doors reviews of his assets,[link widoczny dla zalogowanych]. ��This means that they gathered information to damage a promising presidential candidate. Cheong Wa Dae is the only agency that can control both offices at the same time,[link widoczny dla zalogowanych]."
Since April,[link widoczny dla zalogowanych], the NTS has banned web searches of the property of 27 leading poiliticians -- 108 in all,[link widoczny dla zalogowanych], if their family members are included to prevent web data from being leaked. Among them are ruling and opposition leaders presidential hopefuls and leaders such as GNP chairman Kang Jae-sup and ex-GNP secretary-general Hwang Woo-yeo,[link widoczny dla zalogowanych], the NTS said the same day.
