Pher Pher A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system‚ modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated.[2] DFDs can also be used for the visualization of data processing (structured design). A DFD shows what kinds of data will be input to and output from the system‚ where the data will come from and go to‚ and where the data will be stored. It

Objective: The student is able to use object diagrams to communicate ideas in familiar domains. Initial script for introducing object diagrams: Here we have an object diagram that represents a situation in some particular school. The actual school is much larger; we are only representing a subset of all the situations‚ and there are many more types of links and many more types of objects that might be used. An object diagram can be paraphrased in a natural language. Here is a description that

How to draw SD characters by hand "Super Deformation" or "SD" characters can draw easily by using 2 or 3 heads which is the ratio between the head and the entire character’s height. First‚ you must draw a draft of your character. You must draw 2 circles equally. One represent the head of the character and another is the body. If you use 1:3 ratio‚ you have to draw 3 circles. Second‚ you must draft out their hands and feet. I mean their posture. If your character bends their arms and legs‚ use

4.3 DATA FLOW DIAGRAM A data flow diagram is a graphical technique that depicts information flow and transforms that are applied as data move from input to output. The DFD is also known as Data Flow Graph or Bubble Chart. The DFD is used to represent increasing information flow and functional details. Also DFD can be stated as the starting point of the design phase that functionally decomposes the requirements specifications down to the lowest level of detail. A Level 0 also called a fundamental

I am a big believer in allowance to teach children about money early on. I wish my parents had given us allowance in the way that I learned from a financial course that I took. I don’t know if you’ve ever heard of Dave Ramsey’s Financial Peace but I find that he gives very sound financial advice. He suggests giving children allowance and teaching them how to save‚ give and spend responsibly. Pay them for certain chores kind of like a wage‚ give them 3 envelopes... 1/3 goes into each envelope

3.5 Kinetics of the Alkaline Hydrolysis of Crystal Violet in aqueous solution in the presence of a Cationic and an Anionic Surfactant. 3.5.1 THEORY The alkaline hydrolysis of crystal violet‚ a carbocationicdye(CV+) takes place according to CV+ + OH- ↔ CVOH Where CVOH is the colorless carbinol form of the dye. The kinetics of the reaction can be monitored due to the carbocation form of the dye by measuring the decrease in absorbance at the wavelength corresponding to the absorption maximum(λmax)
