Tips For Indexing Your Database

Posted by on March 16, 2016 in Uncategorized | Comments Off on Tips For Indexing Your Database

If you are using a database or a series of connected databases to store information, you are going to have something that is called an index to look up each item. For example, if you have a database that is full of different types of food, you might first have food categories to help narrow down your search if you are searching for a particular dish. You might have categories such as “vegetables,” “chicken,” and “pork.” Then, each of those keywords will lead you to another table that is full of even narrower search terms. If you search the main food categories table and then go to chicken, you might index a table that contains the entries “grilled chicken” and “fried chicken.” From there, you can index a table that contains “fried chicken sandwich” and “fried chicken tenders.” You need to be sure that you organize your databases in a way that makes sense and results in the answer to the query being returned within a short period of time. Here are some tips for optimizing your database setup so that queries get answers back quickly. 1. Keep Your Indexing Based on Integers, Not Characters It is far easier for a computer to recognize and compare different integers, as opposed to different characters or different strings of characters. If you are starting at the main food categories table and need to find “pork,” it is going to be easier for the computer if you keep them in alphabetical order and then use integer keys that relate to the alphabet order to do look-ups. This will make any searches that you make much faster. 2. Keep the Number of Sub-Tables Small It takes time for a computer to index sub-tables. As a result, you don’t want to go too deep from table to table. Try to organize each sub-table so that you limit the number of tables that you actually have to index in order to get to the answer to a query. In the example of the food query above, you only needed to index three times in order to get to “fried chicken sandwich,” if that were the dish that you were looking for. If you are going to be doing a read-only table, meaning that you aren’t going to be editing any entries in the table or adding to the table, then it is acceptable to require a larger amount of indexing since reads tend to take less time than adds or edits.  For more information, talk to your data manager. He or she will have other tips on how to keep your database setup optimized. For data center management, contact a company such...

Setting Up Or Expanding Your Cabling System? Three Things To Be Aware Of

Posted by on March 9, 2016 in Uncategorized | Comments Off on Setting Up Or Expanding Your Cabling System? Three Things To Be Aware Of

Like many people without a background in IT, you may be vaguely aware that you’ll need cabling services to help you set up or expand data cables that your business may need. Here are some things you’ll have to be aware of as you make cabling decisions for your business. Cable Type You may not know this, but when you experience lag times using the internet, the reason might be that you are using the wrong cables. Typically, your choices will include copper or fiber-optic cables. Copper cables offer basic performance and are suitable for companies who don’t use the internet often or have no need for high bandwidth. They are typically less expensive than the alternative, so if your company can’t spare too much money, copper is a good solution.  Fiber-optic cables, on the other hand, can offer higher internet speeds and bandwidth, which can be important if you have a high number of people trying to access the network at one time. In addition, if you are in an environment where electromagnetic machines might be used, such as a doctor’s office, fiber-optic cables are unlikely to be affected. Because fiber-optic cables tend to be more costly than copper, however, it is important to evaluate your company’s financial standing to determine whether you can justify the expense. Setup Logistics It is not enough to know what kind of cables you’ll need to keep your network going. You have to think about the work involved in setting up those cables. This work might involve removing ceiling panels, drilling holes and other activities that might be disruptive for your employees. If you don’t want to have technicians underfoot during the workday, you can ask that the cabling services company work after hours. If that isn’t possible, you may have to make other arrangements with your employees so that work can continue as the cabling is set up. Maintenance Schedule   Once the cables are in place, you might think that you don’t have to worry about them anymore. However, with continuous use, the cables will have to be properly maintained by professionals to prevent loose connections, overheating, dust infiltration and other problems that could result in a breakdown of the system. Make sure you set up a maintenance schedule to keep your cabling system functional.  The information in this article should help you better understand the choices you’ll need to make when you set up or expand cabling for your company. When you find a suitable cabling services company to do the work, ask for more guidance for the particular needs of your business.
