|
| With Crystal FLOW : |
|
|
 |
You can save more than 1 hour everyday
|
|
|
|
You can achieve better software quality
|
|
|
|
Your software documentation will have better quality and content
|
|
|
|
Your software maintenance will be easier and cost less |
|
|
|
|
Crystal FLOW is a highly productive environment for understanding, browsing and documenting code.
|
|
|
It integrates several tools such as Flowcharts, Rich Trees, DataFlow, CallFlow, Data-Dependency tree, Full HTML
documentation... all in one package. |
|
|
| You can reach for the right tool when you need it. You can perform the task better and in less time.
|
|
|
| When you need to find how a particular variable is used in the project, view its DataFlow.
|
|
|
|
DataFlow combines the power of GREP, Flowcharts and information filtering into one efficient tool. |
|
|
|
It can track data objects even when they are passed as parameters and have different names in the called functions.
|
|
|
| When you need to understand a function, view its flowchart.
|
|
|
|
The flowchart is a major time-saver. For example, when a large function contains nested if's and else's, you can visualize them clearly. It is very helpful in planning code-modifications. |
|
|
| Need to find all the recursive functions in the project?
|
|
|
|
View the Browse Window. |
|
|
|
| If you lose time every day, can you be competitive in the global market place? |
|
| Making design changes? Inherited legacy code? Performing a code review? Generating documentation? You need Crystal FLOW. |
|
|
|
|
|
Understand a function in less time
|
|
|
|
|  If you are not using flowcharts, you are losing time!
|
|
|
|
|
|
Divide-and-conquer very long functions
|
|
|
|
| You can understand a 300 line function in less than 20 minutes
|
|
|
|
| With Crystal flowcharts, you save a huge amount of time.

|
Reduce bugs
|
|
|
|
| Why do we have bugs in our code ?
|
|
|
|
| This is because - we do not have sufficient understanding of the code.
|
|
|
|
The Graphical view increases your understanding of the code.
|
|
|
|
You can detect missed branches or incorrect conditions in your code logic
|
|
|
|
|
|

|
|
|
|
|
Check for correctness, Improve the design
|
|
|

|
|
|
|
|
|
Dig deeper by expanding function-calls
|
|
|
|
|
Expand the function-calls in a CallFlow; Visit the source code of the called functions; keep going deeper
|
|
|

|
|
|
Which functions in the tree use a particular global variable?
|
|
|
|
|
In the Call-tree, Crystal will display the name of the global variable alongside each function that uses it.
|
|
|
|
|
|
View filenames where each function is defined
|
|
|
|
|
In the tree, each node shows the function name and the filename where it is defined
|
|
|
|
|
|

|
|
|
|
|
