First it takes advantage of the sequential structure of decision tree branches so that the order of checking conditions and executing actions is immediately noticeable. Second, Conditions and actions of decision trees are found on some branches but not on others which contrasts with decision tables, in which they are all part of the same table. Those conditions and actions that are critical are connected directly to other conditions and actions, whereas those conditions that do not matter are absent. In other words it does not have to be symmetrical. Third,Compared with decision tables, decision trees are more readily understood by others in the organization. Consequently, they are more appropriate as a communication tool.
Unbalanced Decision Tables are a compromise between Decision Tables and Decision Trees. Decision Trees themselves can become quite complex with enough conditions and actions. Unbalanced Decision Tables provide either a prioritized list of conditions that lead to a set of actions, or a list of conditions that lead to a set of actions. The result is often more concise than either traditional Decision Tables or Decision Trees.
could u send me the answers for the merits of the decision tables
Decision Tree Advantages Easy to understand Map nicely to a set of business rules Applied to real problems Make no prior assumptions about the data Able to process both numerical and categorical data Decision Tree Disadvantages Output attribute must be categorical Limited to one output attribute Decision tree algorithms are unstable Trees created from numeric datasets can be complex
Advantages of decision tree analysis: Easy to interpret, Possible scenarios can be easily added, Value of different scenarios can be determined.

what is a decision tree???
No. A Christmas tree is not part of the Periodic Table of Elements.
You are a table.
Decision trees help managers visualize how their choices will play out within the organization. Using a decision tree, management can assess multiple options at once.
First, you must find a way to uproot the tree. Once you have loosened the tree, pull hard and it might come up. Then, find a way to transport the tree to your table. Once you have the tree next to your table, use something to break the table. Try making small cracks around that base. I don't know why you have a base on your table. Trees don't grow in baseball diamonds anyway. Put the tree in the cracks.
While the entomology of leaf is not known for certain, it is possible it has to do with a leaf on a tree. Since a leaf is an extension of a tree, a table leaf is an extension of a table.
