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 Hertzsprung-Russell Diagram or‚ the H-R Diagram for short‚ is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern‚ which in fact is quite interesting. The H-R Diagram is named for the two astronomers‚ Ejnar Hertzsprung and Henry Russell‚ who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. <br><br>One key
