This document discusses JavaScript concepts including IF-Else statements, Switch statements, popup boxes, and functions. IF-Else statements allow executing different code blocks based on if a condition is true or false. Switch statements select code blocks to execute based on different cases. Popup boxes include alerts, confirms, and prompts. Functions define reusable blocks of code that can accept parameters and return values. The document encourages experimenting with these JavaScript concepts.
Loops in Java. Looping in programming languages is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to true.
Decision Making in Java (if, if-else, switch, break, continue, jump) Decision Making in programming is similar to decision making in real life. A programming language uses control statements to control the flow of execution of program based on certain conditions.

UNIQUE indexes have long held a unique position among constraints: they are the only way to express a constraint that two tuples in a table conflict without resorting to triggers and locks (which severely impact performance). But what if you want to impose the constraint that one person can't be in two places at the same time? In other words, you have a schedule, and you want to be sure that two periods of time for the same person do not overlap. This is nearly impossible to do efficiently with the current version of PostgreSQL -- and most other database systems. I will be presenting Exclusion Constraints, which has been accepted for the next PostgreSQL release, along with the PERIOD data type (available now from PgFoundry). I will show how these can, together, offer a fast, scalable, and highly concurrent solution to a very common business requirement. A business requirement is still a requirement even if your current database system can't do it!

Introduction to control statements in Java. Control statements include Decision making statements, Loop statements, Jump Statements. If statements, While Loops, For Loops, Break and Continue are main flow of control in Java
We are covering following topics:
If...Else...Elseif Statements: if statement executes some code if one condition is true.
Switch Statement: Switch Statement tests a variable against a series of values.
For Loop: For loop executes a block of code a specified number of times.
While Loop: While loop executes a block of code as long as the specified condition is true.
Do…While Loop: Do...While loop will always execute the block of code once, it will then check the condition, and repeat the loop while the specified condition is true.

10 Insightful Quotes On Designing A Better Customer ExperienceYuan Wang
In an ever-changing landscape of one digital disruption after another, companies and organisations are looking for new ways to understand their target markets and engage them better. Increasingly they invest in user experience (UX) and customer experience design (CX) capabilities by working with a specialist UX agency or developing their own UX lab. Some UX practitioners are touting leaner and faster ways of developing customer-centric products and services, via methodologies such as guerilla research, rapid prototyping and Agile UX. Others seek innovation and fulfilment by spending more time in research, being more inclusive, and designing for social goods.
Experience is more than just an interface. It is a relationship, as well as a series of touch points between your brand and your customer. Here are our top 10 highlights and takeaways from the recent UX Australia conference to help you transform your customer experience design.

PHP Lecture 2 - Conditional Statement, Loop, if Statement, if-else statement, Nested if-else, Switch statement, For loop, while loop, do while loop, foreach loop
3. if...else statement- use this statement to execute some code if the condition is true and another code if the condition is false
4. if...else if....else statement- use this statement to select one of many blocks of code to be executedif (time < 12) { document.write("Goede Morgen"); } else { document.write("Goede Middag"); }
7. Switch switch(n){case 1: execute code block 1 break;case 2: execute code block 2 break;default: code to be executed if n is different from case 1 and 2}
12. Functions functionfunctionname(var1,var2,...,varX){some code} The parameters var1, var2, etc. are variables or values passed into the function. The { and the } defines the start and end of the function. Note: A function with no parameters must include the parentheses () after the function name. Note: Do not forget about the importance of capitals in JavaScript! The word function must be written in lowercase letters, otherwise a JavaScript error occurs! Also note that you must call a function with the exact same capitals as in the function name.
