S. Urmela and others  have described a study completely based on the data mining techniques. According to the writers, DDM refers to the distributed data mining. It is an important data mining environment that have the ability to mine larger data in less time. Data mining is a kind of process which is capable to extract effective information from datasets and facts so that reliable decisions can be developed . The writers provided a way where numerous DDM techniques can be reviewed and the level of understanding can be improved. Researchers have classified distributed data mining into major three sections for example agent-based, a classifier based and privacy-preserving. The writers included qualitative designs that helped to gain effective information about DDM techniques and also conducted a literature review in order to evaluate the techniques are applying in recent research. In terms of effectiveness, this paper is more effective that provided complete information about distributed data mining and also included viewpoints of other writers. However, the researchers did not cover benefits and challenges linked with the distributed data mining techniques that produced a research gap but future research will cover such information.
Yuan Huang and others  have reviewed data mining programs used for cloud networks and AI systems. This paper provided a platform to demonstrate applications and importance of data mining algorithms among cloud and AI devices .

David Savage and other  proposed novel algorithm based on the distributed mining programs. The objective of this research is to develop a significant algorithm for mining contrast patterns based on distributed techniques . According to the writers, mining for contrast pattern is a critical task but distributed mining is more effective which is capable to extract information and patterns from images effectively. Numerous kinds of methods are included for example qualitative design, inductive approach, and secondary data collection and content analysis techniques. It is found that current data extraction approaches for contrast patterns are not able to manage dense and larger databases but distributed mining-based programs are more effective that helped to manage such problems. The writers provided a significant mining algorithm by which data can be extracted from larger dimensional databases easily. The writers tested a spark cluster using distributed data mining programs. The future research will include applications and different types of algorithms used in distributed data mining companies.
A few research frameworks currently exist    for using data mining in distributed fashion. Some of them are designed for general environment to execute mining tasks . Some are implemented by using single data mining algorithms. But more algorithms are required for distributed environment. So a general framework is required for applying data mining tools and techniques  . Some researchers have introduced the rationale as new architecture due to huge amount of data and increasing data rapidly. Moreover, data complexity, diversity is also increasing .
Some advance data mining in distributed environment like national security and crime detection are essential  . Such tasks process knowledge discovery in databases   . Data mining in distributed environment is a scientific computing task. It provides facilities of remote computer connected through a network (TCP/IP) to its scientific partners. So using data mining in distributed environment researchers concern in field of Simulation, Data Analysis and Machine Learning  . Due to vast development of Internet data mining are taking place in distributed environment and suitable frameworks are needed in common fashion  .
There are some important requirements those cannot be handle easily in distributed environment, such as Corporate Decision Handling, Decision support system, Management support system, Strategic policy making, Information retrieval, Knowledge analysis, Intrusion detection, etc.
3. Proposed Framework
This proposed framework can play a significant role in distributed database for effective computational and application regarding knowledge discovery  . The proposed framework will provide an environment to perform analysis, clustering, classification, associate etc to find hidden information from large distributed database. Strategic policy or vital decision can be made from that information. A knowledge discovery  also works for actionable knowledge. The actionable knowledge provides a good solution to make decision and also provides an idea of path selection to reach in a certain goal. Decision tree is an important issue in this area. Different data mining algorithms  can be used. A sample diagram of the proposed framework is shown in Figure 1.

data are stored in local database. This may be different work stations or computers those are connected through network  . The model provides better algorithms and performance in distributed architecture . The main steps of the framework that we have proposed:
· Perform the data mining query in the distributed database;
· Create a local data mining model in local level;
· Combined the local model in central site;
· Produce a single model based on combination;
· Apply query on the central combined model to produce required result;
· In necessary back to lower level for better analysis.
Our proposed research work can also be seen as a knowledge framework. It will be as a system for knowledge discovery (KDD)  in distributed database. KDD plays important role in data mining process. The proposed framework will use actionable knowledge   to build specific knowledge discovery services. The framework will provide users with high-level abstractions and a set of services by which is possible to integrate distributed resources to support all the phases of the KDD process. Therefore, it will allow end-users or decision maker to discover knowledge without worrying about distributed environment.
We will use some techniques in the proposed framework. Some techniques may be changed depending on situation whenever developing the framework and also novel techniques can be added. Available techniques are as the followings:
· Classifier learning with meta learning and knowledge discovery framework;
· Collective and collaboration data mining;
· Clustering and association rule mining in distributed environment.
There are many popular algorithms available for distributed model. Most of the model is support by decision tree algorithm and Naïve Bayes algorithm . Due to get some facilities researchers are also using association rule  . Our proposed framework to study data mining to deal complex systems   . Distributed data sources that we proposed will work with both homogeneous and heterogeneous data .
The key requirements to do mining in this framework is using the better applications of algorithms based on Attribute-value description and required output  . Also, we want to use data mining algorithms to created data model for data analysis. The algorithms should be studied for specific pattern and trends.
We will try to use at agriculture and bank sector in Bangladesh. Using this novel technique long term strategic policy in agriculture or bank will be made. So, these sectors will be developed more and there will be a big change for wellbeing  .
The proposed framework is designed for learning association rules , classifier and meta classifier , link analysis, frequent episodes  for sequence analysis and supporting distributed environment. While, analyzing and summarizing raw data is an essential task for this framework. There are some similar successful projects as Nimrod, Keplar, Taverna, WEKA, GridMiner, RapidMiner, R Language, etc.
Advanced tools and techniques play significant roles in distributed environments over the wireless and wired network. The environment deals with many sources of data and unlimited computer nodes with unlimited user. To analysis data, suitable framework is required to work with the complex system.
