DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations

The circular flow of income model is a theoretical representation of the economy. It shows the distribution of income within the economy and the interaction between the different sectors in a modern market economy. The five-sector model is a more elaborate model in comparison to the basic‚ two‚ three and four sector models. The model represents an economy like Australia and divides the economy into five main sectors. The first sector in the model is the Households sector. This sector refers to
