UNITED NATIONS, Nov. 22 (Xinhua) -- An inter-agency UN-Red Cross-Syrian Arab Red Crescent convoy has managed to reach Rastan city in northern rural Homs to deliver food, water and other supplies to local people in the area, a UN spokesman said here on Tuesday.


""This is the first cross-line inter-agency convoy in November and the fourth inter-agency delivery to the area this year,"" spokesman Stephane Dujarric said at a daily news briefing.


Rastan, about 20 km north of Homs, was last reached on July 27.


""While we welcome the convoy to Rastan today, it is worrying that no inter-agency convoy had been able to deploy until this late in November,"" Dujarric said.


""The result is that we are once again unlikely to reach more than a small portion of those for whom we receive formal approval to access -- due to deliberate restrictions, needless administrative hurdles as well as insecurity.""


He said the UN would continue to call for safe, sustained and unimpeded humanitarian access to all in need in Syria, particularly those living in hard-to-reach and besieged areas.


Rastan is the third largest city in the Homs province with a population of a bit more than 100,000. The rebel-held countryside of the central province has been under severe siege along with constant aerial bombing.


The Sirian civil war broke out five years ago after the anti-government protests escalated into an armed conflic, with more than 250,000 people being killed and millions fleeing their homes to escape the war.

Database Indexing 芒鈧€?an Introduction

Author: Stephen J. Richards




Databases are excellent data storage and retrieval tools Authentic Mathew Barzal Jersey , ranging from simplistic tables of information to complex, intricate collections of multiple linked databases. A database is created and named based on the particulars of its application, and stores data in tables consisting of an organized collection of rows and columns. Data may be manually entered into databases, but is more commonly written dynamically into databases by web sites or by connected software applications. Companies often maintain constantly growing databases containing data such as client information, financial figures and performance analyses John Tavares Jersey , for instance, and the ever expanding nature of such databases warrants techniques for streamlining the process of locating specific pieces of information within them. Indexing allows for the rapid retrieval of specified data by queries, and is therefore a powerful tool for databases containing hundreds or even millions of records.



At initial set up, the creator of a database typically defines the primary key, which is a column within which the data in each row is unique. For example Andrew Ladd Jersey , a column containing client last names would not be identified as the primary key, as multiple entries may have the same name. However, a column containing unique client ID numbers could be designated as the primary key. When the primary key is defined, an index is actually created. When data from the column defined as the primary key is requested in the form of a query, the database automatically utilizes this index to quickly locate the requested data. However Mathew Barzal Jersey , the primary key is likely not the only column that will need to be searched for data. For queries that will be used frequently, an index can be added to the appropriate column to speed up the process of data selection. Indexes speed up the process of retrieval while lessening the workload the server must endure to perform the search.



Much like the way the index of a book makes finding a topic easier, database indexes make locating a queried piece of data easier. Instead of flipping through and reading each individual page of a book to locate a topic, you can refer to the book’s index and know where to look right away. Likewise, instead of a query asking each record in a database if it contains the information being sought New York Islanders T-Shirts , it can be directed by an index to the appropriate data.



Effective use of indexes requires establishing a balance between an efficient number of indexes and too many. Since indexes take up space, using too many can counteract the purpose by slowing the database down. Indexes may be unnecessary for smaller databases, where the queries can locate data quickly and easily. But indexes are dynamic and powerful tools for optimizing the performance of large databases.
