managing multiple Databases in php

Hi,

This is important to manage your database connections in php if you are using many connections in a single application. you can use single ton pattern in php to make is clear.

Exe:

class Connector {
    private $conn;
    private $intranetdb = 'jprod';
    private $metricsdb = 'metrics_prod';
    private function __costructor(){
           
    }
    static function intranetDb(){
        return 'jprod';
    }
    static function metricsDb(){
        return 'metrics_prod';
    }
    static function makeConnection($host, $username, $password){
        return $this->conn = mysql_connect($host, $username, $password);
    }

javascript private members of a object

Private Members in JavaScript

Douglas Crockford
www.crockford.com



JavaScript is the world's most misunderstood programming language. Some believe that it lacks the property of information hiding because objects cannot have private instance variables and methods. But this is a misunderstanding. JavaScript objects can have private members. Here's how.
Objects

JavaScript is fundamentally about objects. Arrays are objects. Functions are objects. Objects are objects. So what are objects? Objects are collections of name-value pairs. The names are strings, and the values are strings, numbers, booleans, and objects (including arrays and functions). Objects are usually implemented as hashtables so values can be retrieved quickly.

If a value is a function, we can consider it a method. When a method of an object is invoked, the this variable is set to the object. The method can then access the instance variables through the this variable.

Objects can be produced by constructors, which are functions which initialize objects. Constructors provide the features that classes provide in other languages, including static variables and methods.
Public

The members of an object are all public members. Any function can access, modify, or delete those members, or add new members. There are two main ways of putting members in a new object:
In the constructor

This technique is usually used to initialize public instance variables. The constructor's this variable is used to add members to the object.

function Container(param) {
this.member = param;
}

So, if we construct a new object

var myContainer = new Container('abc');

then myContainer.member contains 'abc'.
In the prototype

This technique is usually used to add public methods. When a member is sought and it isn't found in the object itself, then it is taken from the object's constructor's prototype member. The prototype mechanism is used for inheritance. It also conserves memory. To add a method to all objects made by a constructor, add a function to the constructor's prototype:

Container.prototype.stamp = function (string) {
return this.member + string;
}

So, we can invoke the method

myContainer.stamp('def')

which produces 'abcdef'.
Private

Private members are made by the constructor. Ordinary vars and parameters of the constructor becomes the private members.

function Container(param) {
this.member = param;
var secret = 3;
var that = this;
}

This constructor makes three private instance variables: param, secret, and that. They are attached to the object, but they are not accessible to the outside, nor are they accessible to the object's own public methods. They are accessible to private methods. Private methods are inner functions of the constructor.

function Container(param) {

function dec() {
if (secret > 0) {
secret -= 1;
return true;
} else {
return false;
}
}

this.member = param;
var secret = 3;
var that = this;
}

The private method dec examines the secret instance variable. If it is greater than zero, it decrements secret and returns true. Otherwise it returns false. It can be used to make this object limited to three uses.

By convention, we make a private that parameter. This is used to make the object available to the private methods. This is a workaround for an error in the ECMAScript Language Specification which causes this to be set incorrectly for inner functions.

Private methods cannot be called by public methods. To make private methods useful, we need to introduce a privileged method.
Privileged

A privileged method is able to access the private variables and methods, and is itself accessible to the public methods and the outside. It is possible to delete or replace a privileged method, but it is not possible to alter it, or to force it to give up its secrets.

Privileged methods are assigned with this within the constructor.

function Container

JSON (javascript object notification)

Hi all,

This is one of the technology you can use to make your javascript and ajax objects more powerfull.

declaring object:

var newJsonObj = {}
vat newJsonArr = [];

newJsonObj = { "tty" : android,
"name", aniruddha das,
"posts" : [
{"":thid,}
]
}

jave project arcteture

Hi,

Project Architecure means what are the tiers in our project with flow diagram.

supposoe our project contains five tiers like client tier ,presentation tier, Business tier,Integration tier,Data tier. then we draw the all tiers flow.

project approch is different from project architecure. sorry here i can't insert my own project architecure diagram. if any one want project architecure , project approch then mail me.

Client tier:

• IE Browser (default) from which the end user will access the application
• The request from the browser will be submitted to the Application Server using HTTP protocol.
• The Response from the presentation layer (struts framework) will be interpreted into html pages to view on the browsers.
• Presentation Tier:

Struts Framework with Tiles
• On Request from the browser, the appropriate Action Class handles the user request. The Action class then connects to the business tier via Service Business Delegate.
• Tiles have been used to create a set of pages with a consistent user interface (e.g.: the same navigation bar, header, footer, etc.).
• Taglibs are used for displaying tabular data (e.g. search results) in a consistent fashion, with pagination.
Business Delegate layer
• Enable the Struts Action classes to be unaware of underlying Session Beans
• Encapsulates the invocation of Service Locator to locate them.

Advantages of Struts
‘Centralized File-Based Configuration’, i.e. rather than hard-coding information into Java programs, many Struts values are represented in XML or property files.
This loose coupling means that many changes can be made without modifying or recompiling Java code.
Validation of the user entry fields in the jsps to be handled by entries in the validation.xml and defining validation rules in validator-rules.xml.
Internationalization of the static components of the screen as field and button labels, titles, error messages etc.
This approach also lets Java and Web developers to focus on their specific tasks (like implementing business logic, presenting certain values to clients.) without needing to know about the overall system layout.

Business Tier

• The Business Delegate identifies the business service class (the Session EJBs) and delegates client request to the EJBs. Internally, the session beans are shallow, and delegate all business logic requests to business logic POJOs, which in turn implement the actual functionality.
• The Business Logic POJOs encapsulate the server side business logic. They do not use Hibernate directly, but instead call upon Data Access Objects (DAO) to work with the model. Parameters and return values are modeled as Data Transfer Objects (DTO), and hence no Hibernate model classes will ever leave the DAO layer. The business logic is made available in the business service class, which increases maintainability and easy debugging, if necessary.

Hibernate/DB Tier
The DAOs encapsulates the database access. For all practical purposes, we are using Hibernate (v 2.1) as the OR mapping layer. This saves development time to write SQLs for executing insert and update statements, find by primary key etc. For each value object that directly or compositely represent a table in the database, we have Hibernate mapping files.
For some complex data retrieval, however we will be using raw SQLs (independent of database) from the DAOs and populate the Value Object POJOs. In those specific cases, the DAOs will be having direct access to the Databases using the available connection. The connection properties of the ‘DB Manager’, holding the data sources, direct the request to the appropriate database.

Issues that may rise of Hibernate
• Hibernate no longer supports dynamic proxies
• The Hibernate has issues using Microsoft's driver especially when using SqlServer2000. It appears that the failures are due to some strange handling of dates.
• Hibernate has issues with Informix Databases due to the way JDBC implementation is done in Informix.

Android Development

Android development is very easy now with Android Studio 2.0. Google guys changed almost everything they can to make the android development super fast and easy. The best part is lots of configuration are automated and you dont have to write or make configuration related changes to start porject.

Developing application in Android studio 2.0

Now a days developing android application is really easy, i remember those days when I started with eclipse and there were hell lot of bugs everywhere. 

Templates:

To start a new porject in android studion 2.0, you can go to the new project wizard and then you will get more options like which types of project you want to create, what layout you want to use, how your pplication will react to the UI, etc. Also they included new now a days device options as well. like if your app will run on android watch, tv etc.

if you are new to android development, you can get all kind of latest news and help at  developer.android.com.
