Suatu sistem dapat di gambarkan secara umum menggunakan diagram berbentuk blok sehingga memudahkan untuk mengetahui gambaran umum dari sistem tersebut.  Gambaran serangkaian proses utama yang ada dan saling berhubungan tersebut lebih umum di sebut dengan block diagram. Istilah block diagram, flowcart dan IPO diagram dapat di baca di  kamus http://pascal.computer.org/sev_display/index.action dan secara singkat di kutip pada naskah berikut ini:

Block Diagram :

• a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks
• a diagram of a system, computer, or device in which the principal parts are represented by suitably annotated geometrical figures to show both the functions of the parts and their functional relationships

FlowChart

• a graphical representation of a process or the step-by-step solution of a problem, using suitably annotated geometric figures connected by flowlines for the purpose of designing or documenting a process or program
• graphical representation of the definition, analysis, or method of solution of a problem in which symbols are used to represent operations, data, flow, equipment, etc
• a control flow diagram in which suitably annotated geometrical figures are used to represent operations, data, or equipment, and arrows are used to indicate the sequential flow from one to another

Input Process Output (IPO) Chart

• a diagram of a software system or module, consisting of a rectangle on the left listing inputs, a rectangle in the center listing processing steps, a rectangle on the right listing outputs, and arrows connecting inputs to processing steps and processing steps to outputs
