  Catalyst Development - LogicGem Overview
Presenting decision procedures in a tabular form goes back at least to ancient Babylon, where the rules for performing multiplication of cuneiform numerals were baked in clay tablets for students.
The early decision table programs were written in either mainframe assembly languages or COBOL, so they could not easily be rewritten to run on early mini-computers (or later, to the first personal computers), even if the machines had had the required storage available at that time.
Decision tables are useful at all phases of software development for the simple reason that all phases of software development need correct logic.

 Decision table - Wikipedia, the free encyclopedia
Some decision tables use simple true/false values to represent the alternatives to a condition (akin to if-then-else), other tables may use numbered alternatives (akin to switch-case), and some tables even use fuzzy logic or probabilistic representations for condition alternatives.
The limited-entry decision table is the simplest to describe.
In decision tables, when conditions are omitted, it is obvious even at a glance that logic is missing.

 Decision Tables
Decision tables are used to lay out in tabular form all possible situations which a business decision may encounter and to specify which action to take in each of these situations.
A decision table is a tabular form that presents a set of conditions and their corresponding actions.
We now begin to build the decision table by listing the condition descriptions in the left margin of the upper part of the table and the action descriptions in the left margin of the lower part.

A decision may be characterized on a continuum from unstructured to structured (Simon 1960) [1].
Decision trees are a useful tool for expressing complex decision variables in a format conducive to human visualization.
A decision table is a two-dimensional matrix with one row for each possible action and one row for each relevant condition and one column for each combination of condition states.

 Multi-Criteria / Dimensions in Decision-Making   (Site not responding. Last check: 2007-10-20)
Decision analysis looks at the paradigm in which an individual decision maker (or decision group) contemplates a choice of action in an uncertain environment.
Criterion outcomes of decision alternatives can be collected in a table (called decision matrix or decision table) comprised of a set of columns and rows.
The decision matrix is a central structure of the MCDM since it contains the data for comparison of decision alternatives.

 Truth table - Wikipedia, the free encyclopedia
A truth table is a mathematical table used in logic — specifically in connection with boolean algebra, boolean functions, and propositional calculus — to compute the functional values of logical expressions on any of their functional arguments, that is, with respect to the various possible combinations of values that their logical variables may take.
Truth tables are used to compute the values of propositional expressions in an effective manner that is sometimes referred to as a decision procedure.
Truth tables are a simple and straightforward way to encode boolean functions, however given the exponential growth in size as the number of inputs increase, they are not suitable for functions with a large number of inputs.

 HELP for the Decision Table   (Site not responding. Last check: 2007-10-20)
A decision table is a table the displays different paths one can take to produce quality software.
The text in the first column of the table tells what the possibility is. The text box on the top is where the user enters the estimated cost for that path.
The second part is a table that tells the user what the least expensive decision is. It also shows the difference in cost between the least expensive and the rest of the decisions.

 Business Rules: The Misunderstood Decision Table
Just like the production system is an invention of the 1970's for which efficient algorithms were developed in the 1980's and 1990's, just so the decision table and tree are inventions of the 1950's for which efficient algorithms were developed in the 1960's and 1970's.
Then this simple decision table is typically converted into a different problem space which has more efficient solution algorithms.
When the efficient decision table algorithms are combined with other techniques like rule chaining, the result can be rather zippy systems for situations where inferencing is not necessary or the numbers of rules and facts are small.

 Decision tables
A decision table is a table composed of rows and columns, separated into four separate quadrants.
In order to build decision tables, you need to determine the maximum size of the table, eliminate any impossible situations, inconsistencies, or redundancies, and simplify the table as much as possible.
Calculate the maximum number of columns in the decision table by multiplying the number of alternatives for each condition.

The purpose of using DTC in a model is to create similar decision table to be referred by a program.
In the second step, you build the "decision table" for your DTC.This can be a very short excercise or a very long one, depending on the complexity of the business rules (which necessarily means the number of rules) that you are going to build into DTC.
Adding a component to the decision table is very much similar to adding a component on a model canvas.

 Clad having majority decision address table controller (US5450399)
A cell assembly disassembly facility for interconnecting a local area network and an ATM switch includes an address table and a cell buffer for receiving ATM cells from the switch.
A majority decision is made on the entry groups to determine a winner.
When a packet is received by a packet buffer, the address table is searched for a DA field using the destination of the packet as a search key, and a VPI and a VCI are read from the entry of the DA field into each ATM cell that is sent to the ATM switch.
