Engineering Design Process

Work Design 

Enginnering design process is a process in matters relating to design engineering. Engineering Design Process related to system design, decision-making processes, with optimal processing resources, and can meet the objective of making the product. Engineering Design Process is closely connected with the design. Design itself for the design of something that we will create. To get a good draft we need some skills like Knowledge (in the field of mathematics and other subjects), Skill (Planning, Teamwork, Documentation), Creativity, and Reuse.

Engineering Design process itself starts from the abstract look, then make it a common thing (general), then specified, unspecified setelh, dijadikanlah new models, and applied to the real world. Last re-verified the results obtained there to see what needs fixing what is not. In the engineering world, we as engineers should know about validation, verification, and testing. Validation itself is the ability to find things that people need, verification helps us to make better products, and final testing is to check what the product is worth. To make a good design, it takes a combination between the two mindset, namely Presfiktif (More inclined to algorithmic, systematic) and Descriptive (Finding solutions - with creative solutions).

Biometric Technology

Fingerprint Technology

Humans evolved and evolved from the stone age before, until now. Many things change in human development, including technology. If a few years ago, people still have to use a key to the security of goods, houses, etc., use a pin number that may be forgotten, and so forth, now comes a new technology called Biometric Technology. Own notion is Biometric Technology is a technology that uses human body parts that can describe a person. This technology provides ease and accuracy as well as better security than previous security technologies. Examples of these technologies are fingerprint, face recognition, and retina-sensor. This technology is now widely used, both in schools, universities, malls, workplaces, banks, hospitals, etc..

The system itself works as follows: on the Sensor Module -> go to Quality Assessment -> then checked in Matching and Decision Making -> and checked again in the System Database Module. Look of the excess, Biometric Technology has 7 factors that could adjust everyone, that is owned by everyone, unique, permanent, can be acquired easily, a good degree of accuracy, acceptability, circumvention. Generally, the body parts used in Biometric Technology is the retina, fingerprint because these were a unique part of the body, every human being is different, and the possibility of minor changes.

Exercise PHP - 1

Welcome back! We have learned about PHP and MySql things. Now we will try some code in PHP and run it in your browser.

First you need some editor  for your code. There are some editor that can be used. For me, i’d like to use Adobe Dreamweaver as editor, you can buy it or searchin google for free product of it. 

But if you want free edition editor, you can download Notepad++. It’s simple application but have many functions. Not only PHP code, notepad++ can handle many programming language, such as Java, C++,Sql, css, html, and many others.

So now, i assume you have your own editor now, Let’s start.

1.       First of all, run your xampp ontrol panel and start apache and mysql service.

2.      Second, go into your explorer, go into : C:\xampp\htdocs

 Then create new folder, for example : Exercise

Learning PHP - Basic 2

Now part 2 of Learning PHP is about Operator in PHP and Parsing Variable. We will discuss more the theory in this post and the excercise in another post.

Operator
Operator is object between two variable in PHP or it can be in one variable, that will change another variable's value, or the variable's value itself. Hmm maybe you still hard to understand this, look at this example :
$x = 1 + 2;
x is variable
1 and 2 is value
and + is the operator

Learning MySql - DML

Data Manipulation Language (DML) is used to manipulate the database or we call it database maintenance. There are many syntax include, but we will discuss the most used syntax, SELECT, UPDATE, DELETE, INSERT, TRUNCATE.

• INSERT

It's used to insert the data into the table. There are 2 variant to write the insert syntax, with type the column name, and without type the column name.

Learning PHP - Basic 1

Welcome back! In last posts we have learned how to create database in MySql, now we will learn about PHP, the code on server-side. PHP (PHP Hypertext Preprocessor) is code/script that running on server-side, the script will create an application that can be integrated with HTML, so the web will work dynamic, not static.

PHP Rule

Learning MySql - Creating Database

Today we will learn how to create database in MySql. First i will give you an example of ERD. You can learn about ERD in previous lesson. I will make the database called 'inventory'.

ERD Inventory
