-### **Gardeners Green Thumb Decision Support System** (GGD-DDS)
+## **Gardeners Green Thumb Decision Support System** (GGD-DDS)
 
 An open source rule engine, GGD engine and complex event processing (CEP) engine for Java™ and the JVM Platform.
 
 Drools is a business rule management system with a forward-chaining and backward-chaining inference based rules engine, allowing fast and reliable evaluation of rules and complex event processing. 
 A rule engine is also a fundamental building block to create an expert system which, in artificial intelligence, is a computer system that emulates the decision-making ability of a human expert.
 
-Putting this together a decision support system is designed with the help of drools library which is used in the project.
-The service of decision support system is inferring knowledge from the available data of the greenhouse, the user input, and historical data what a user/the gardener should do & which action a gardener should execute to be successful with the growing process of the plants. 
-These actions are called goals. 
-The list of inferred active goals is offered to other services of the system.  
+Putting all of this together, a decision support system is designed with the help of drools library which is used in the project.
+The service of decision support system is inferring knowledge from the available data of the greenhouse, the user input, and historical data what a user/the gardener should do. 
+The inferred knowledge derived from the algorithm are presented to the gardener where an action is taken. 
+These actions can be presented as goals where each goal is offered to other services of the system (partners). 
  The approach of the DSS is based on three eu.hsrw.ias.ggd.MainExe concepts:
 
-**Fact knowledge (Knowledgebase)**
+###**Facts Knowledgesession,and Knowledgebase**
 
-1. Hardware Information(sensor data info)
-2. Data information was given by an expert that is overwriting sensor data
-3. User Input (We assume that the user is every time honest and that  input is every time correct)
+***Facts are nothing but plain old java objects (POJO) that represents the data which serves as input for rules.***
 
-**Rules (General structure, if premises then consequence)**
-1. Explicit given by expert (before and during runtime)
+***Knowledgesession :This component holds all the resources required for firing rule. 
+Here, all facts are inserted into the single session, and then matching rules are fired.***
+
+***KnowledgeBase is an interface which manages a collection of knowledge definitions like rules.
+Knowledge packages are created by grouping knowledge definition.***
+
+Since the creation of Knowledge packages is very expensive, KnowledgeBase stores and reuse them. 
+Knowledge Sessions are created from KnowledgeBase, which consumes less memory. 
+KnowledgeBase keeps track of each Knowledge Session, so that updates to knowledge base can be applied to all the session at run time. 
+Another advantage of KnowledgeBase is that, it is completely serializable. 
+We can restore serializable object of KnowledgeBase rather creating a new one.
+In the following case StatefulKnowledgeSession are used. 
+So facts are inserted first and stored to KnowledgeSession where it is latter on provided to Knowledgebase. 
+
+
+###**Rules (General structure, if premises then consequence)**
+1. Rules are given explicitly by the expert. The list of rules created for this project are:
    1. Battery
    2. Dielectric Permittivity 
    3. Precipitation

-**Goals**
-1. Goals are active rules which are able to change the fact

-#### **Build**
-Run the MainExe.java which is part of the eu.hsrw.ias.ggd package
-#### **Usage**
+
+### **Build**
+1. Go to Build and build project in order to index all the dependecies required.
+2. Run the *MainExe.java* which is part of the src/main/java/eu.hsrw.ias.ggd package
+
+### **Usage**
 You can reuse the project by changing the UserCredentials.java file located on the Credentials package.
-It is possible to create new rules tailored to the needs.
-#### **Examples**
-For each sensor mentioned in the list of rules an example is given. You may change the values based on the needs of the expert/user.
