If the performance of an SQL server is degrading, it is a reason for concern for the administrator as well as the users. Here are some universal tips that will tune up the performance of your SQL server.

1. For accessing remote servers over sluggish links, it is advisable to use stored codes and T-SQL statements. The same applies to managing large databases. Enterprise Manager should be used only if you are high on resources.
2. In order to use the locking and logging resources more judiciously, use of table variables is advised as opposed to temporary tables.
3.  One way to take some load off your server and answer queries in a more comprehensive fashion is to return only required columns of a table for a query and not all columns.
4.  Using the truncation instead of delete commands for deleting rows from a table makes operation faster. This is because when the delete command is used, entries are added to the log file for individual row deletions.
5.  Using constraints in place of triggers can also enhance the performance of your server.
6.  One should understand that using the DISTINCT clause causes degradation of performance.
7.  To perform row-by-row operations, use of correlation sub-queries or derived tables instead of SQL server cursors should be preferred. SQL server cursors are known to cause performance issues.
8. One ingenious way to reduce network traffic is the use of UDFs (User Defined Functions), which have Transact-SQL statements used to capture codes for repetitive use.
9. Union all statements are executed faster than UNION statements, since the former does not try to find duplicate rows, unlike the latter.

If you want to develop a custom based applications, then PHP is your most viable option.  

The success of this server side scripting language lies in its suppleness to design websites and applications with greater functionality.  It is compatible with numerous frameworks.  Zend Framework offers developers a set of libraries written in compliance with today’s best PHP-programming techniques. It is an open-source software framework for PHP5. It has a flexible architecture that lets you build interactive web applications and web services effortlessly. One of its strengths is the highly modular Model-View-Controller design, which makes the code more reusable and easier to maintain and lets you focus on the big picture. So here is a list of perks Zend framework user can enjoy:

1. Loosely coupled: The Zend Framework can be used as a component library. This means that you can choose to use only one or a subset of components available within the framework. If you wish to use only Zend pdf you are free to do so without using other components of the framework
2. Ease of use: By design, Zend Framework provides a simple collection of classes. You can use Zend MVC components to create a fully-functional ZF project, or you have the option to use just the components you need.
3. Extend Classes: Zend Framework is a fully object-oriented framework, and as such, it utilizes a lot of object-oriented concepts like inheritance and interfaces. Customization of ZF allows you to create unique functionality for your project.
4. Tooling and Rapid Application Development (RAD): The initial application setup can be tricky and tiresome and RAD offers tooling support and a command line client. This helps PHP web application by easily generating project architecture, MVC and other features.
5. Standardized Database: Zend framework uses the best practice of standard database programs; thereby allowing PHP developers to build application models based on the database engines they require.
6. Striking URLs: Almost all major frameworks enhances the appeal of URLs making it more attractive and easy to access.
7. Built-in comprehensive Validators: Drop the idea of manually entering all the validation criteria for your forms. Just instantiate a new form validator object and instruct it as per your requirement and let the framework do its work.
8.  MVC Components:  Zend framework offers Model View Controller architectural pattern to isolate business logic from user interface.
9.  Web and CLI programming: Write CLI scripts using ZF. Zend_Console_GetOpt component provides argument parsing functionality.
10. Enhanced Code Quality: Zend uses the trusted object-oriented design patterns, where  almost all the components can be easily extended. The components of Zend Framework are unit tested using PHPUnit. All components have at least 80% code coverage
11. Internationalization and Localization: Since PHP web application is usually outsourced to countries like India, therefore it has become imperative to add certain languages to the web applications. This tool allows PHP developers to easily add a particular language in order to cater to the expanding markets.

No wonder, proficiency in Zend PHP Framework offers you a differential advantage. So, accelerate your career by enhancing your skills using uCertify’s Zend Framework course and labs. Pass the Zend PHP certification exam and flaunt your credentials. Act now to take the lead!

Did you know by 2020, approximately 26 billion objects will be linked together in the internet? The expression “Internet of Things” (IoT) was coined by the British technology pioneer Kevin Ashton in 1999. It is concept that converges the unconnected objects and processes with the ones that are digital- by their nature. IoT is enabling the advancements with its standardized, ultra-low-power wireless technologies. Likes of Bluetooth and ZigBee have proven instrumental in driving sensor and node implementations, while Wi-Fi and cellular connectivity serve as a backbone for transferring the collected data to the cloud.

3 Ways It’s Going To Impact Use

Everyday objects is going online:

The Internet has been almost completely dependent on people for its supply of information. But in the future, things will be able to input data themselves. It will be as though a net is laid over the physical world, linking up and processing the abundance of data generated by “smart” things and ubiquitous sensors. This is expected to reveal patterns and make everything from energy to logistics transparent and potentially open to real-time optimization.

Untapped potential in IoT: In its 2013 “Global Information Technology Report,” the international strategy consultancy company Booz & Company studied the economic and social effects of digitization. According to this study, a 10-percent increase in a country’s digitization rate leads to a 0.75 percent higher gross domestic product (GDP) per capita and a 1.02 percent lower unemployment rate.

M2M Market Share Worldwide: A key technology for connecting everyday objects to networks is radio frequency identification (RFID), in which data from a chip is transmitted via wireless links. Market research firm Navigant Research reports that in 2012, almost 40 million devices around the world were equipped with Zigbee. In 2020, that figure is expected to grow to over 200 million — a more than five-fold increase within just eight years.
