Advantages Of ERP

In the absence of an ERP system, a large manufacturer may find itself with many software applications that cannot communicate or interface effectively with one another. Tasks that need to interface with one another may involve:[citation needed]

* ERP systems connect the necessary software in order for accurate forecasting to be done. This allows inventory levels to be kept at maximum efficiency and the company to be more profitable.
* Integration among different functional areas to ensure proper communication, productivity and efficiency
* Design engineering (how to best make the product)
* Order tracking, from acceptance through fulfillment
* The revenue cycle, from invoice through cash receipt
* Managing inter-dependencies of complex processes bill of materials
* Tracking the three-way match between purchase orders (what was ordered), inventory receipts (what arrived), and costing (what the vendor invoiced)
* The accounting for all of these tasks: tracking the revenue, cost and profit at a granular level.

ERP Systems centralize the data in one place. Benefits of this include:

* Eliminates the problem of synchronizing changes between multiple systems - consolidation of finance, marketing and sales, human resource, and manufacturing applications
* Permits control of business processes that cross functional boundaries
* Provides top-down view of the enterprise (no "islands of information"), real time information is available to management anywhere, anytime to make proper decisions.
* Reduces the risk of loss of sensitive data by consolidating multiple permissions and security models into a single structure.
* Shorten production leadtime and delivery time
* Facilitating business learning, empowering, and building common visions

Some security features are included within an ERP system to protect against both outsider crime, such as industrial espionage, and insider crime, such as embezzlement. A data-tampering scenario, for example, might involve a disgruntled employee intentionally modifying prices to below-the-breakeven point in order to attempt to interfere with the company's profit or other sabotage. ERP systems typically provide functionality for implementing internal controls to prevent actions of this kind. ERP vendors are also moving toward better integration with other kinds of information security tools.

What is ERP

ERP is a Software tool that accelerates the business process of an enterprise.

In brief, it helps each person at every level of an enterprise, by providing accurate revealing reports at an auspicious time. And this makes ERP the optimized solution for any problem, facilitating appropriate decision-making in a timely manner.

Enterprise resource planning (ERP) is an Integrated computer-based system used to manage internal and external resources, including tangible assets, financial resources, materials, and human resources. It is a software architecture whose purpose is to facilitate the flow of information between all business functions inside the boundaries of the organization and manage the connections to outside stakeholders. Built on a centralized database and normally utilizing a common computing platform, ERP systems consolidate all business operations into a uniform and enterprise-wide system environment.

An ERP system can either reside on a centralized server or be distributed across modular hardware and software units that provide "services" and communicate on a local area network. The distributed design allows a business to assemble modules from different vendors without the need for the placement of multiple copies of complex and expensive computer systems in areas which will not use their full capacity

Ajax guide

simple Ajax guide :

AJAX is about updating parts of a web page, without reloading the whole page.

What is AJAX?

AJAX = Asynchronous JavaScript and XML.

AJAX is a technique for creating fast and dynamic web pages.

AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page.

Classic web pages, (which do not use AJAX) must reload the entire page if the content should change.

Examples of applications using AJAX: Google Maps, Gmail, Youtube, and Facebook tabs.

Php interview questions

1)What’s the difference between include and require? - It’s how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.

2)Explain the ternary conditional operator in PHP? - Expression preceding the ? is evaluated, if it’s true, then the expression preceding the : is executed, otherwise, the expression following : is executed.

3)For printing out strings, there are echo, print and printf. Explain the differences. - echo is the most primitive of them, and just outputs the contents following the construct to the screen. print is also a construct (so parentheses are optional when calling it), but it returns TRUE on successful output and FALSE if it was unable to print out the string. However, you can pass multiple parameters to echo, like:



and it will output the string "Welcome to TechInterviews!" print does not take multiple parameters. It is also generally argued that echo is faster, but usually the speed advantage is negligible, and might not be there for future versions of PHP. printf is a function, not a construct, and allows such advantages as formatted output, but it’s the slowest way to print out data out of echo, print and printf.

4)What’s the difference between htmlentities() and htmlspecialchars()? - htmlspecialchars only takes care of <, >, single quote ‘, double quote " and ampersand. htmlentities translates all occurrences of character sequences that have different meaning in HTML.

5)What is the use of ob_start() in PHP?
Actually, ob_start() tells PHP to start output buffering, meaning that anything you output after ob_start() wont be sent to the browser until the end of the page or ob_end() etc are reached.

So that means that once you use ob_start() and echo something out, you can still set cookies without any errors. For example:


ob_start();
echo "this will work";
setcookie("test", true);

ob_end_flush();

?>

6)what is the difference between ph4 and php5
In PHP4, everything was passed by value, including objects. This has changed in PHP5 -- all objects are now passed by reference.
PHP5 introduces a new unified constructor/destructor names. In PHP4, a constructor was simply a method that had the same name as the class itself. This caused some headaches since if you changed the name of the class, you would have to go through and change every occurrence of that name.

In PHP5, all constructors are named __construct(). That is, the word construct prefixed by two underscores. Other then this name change, a constructor works the same way.Also, the newly added __destruct() (destruct prefixed by two underscores) allows you to write code that will be executed when the object is destroyed.

Type Hinting

PHP5 introduces limited type hinting. This means you can enforce what kind of variables are passed to functions or class methods. The drawback is that (at this time), it will only work for classes or arrays -- so no other scalar types like integers or strings.
PHP finally introduces exceptions! An exception is basically an error. By using an exception however, you gain more control the simple trigger_error notices we were stuck with before.

7)What are the differences between Get and post methods

1. By using Post method we can send unlimited data,But it's
not possible in the case of Get. Get support maximum 200
characters or 2 MB data.
2. Get method is not secure as anyone can see it's content
in the URL.It doesn't happen in case of Post method.

8)How can we submit a form without a submit button?

using javascript
document.form.submit();
9)How many ways we can retrieve the date in result set of mysql using php?

4 ways

1. mysql_fetch_rows
2. mysql_fetch_object
3. mysql_fetch_assoc
4. mysql_fetch_array

mysql_fetch_object : will return the results from database
as objects. fields will be accessible like in objects
i.e $result->name,$result->cust_name

mysql_fetch_array : will return the results from database as
array. fields will be accessible like in objects
i.e $result[name],$result[cust_name]

10)What is the difference between $message and $$message?


$Message = "php";
$you= "java";

echo $message //Output:- php
echo $$message //output :-java

It means
$message is a variable and
$$Message is variable of variable

A variable of variable allows us to change the name of
variable dinamically
