In e-government, the mining techniques are considered as a procedure for extracting data from the related web
application to be converted into useful knowledge. In addition, there are different methods of mining that can be applied to different government data. The significant ideas behind this paper are to produce a comprehensive study amongst the previous research work in improving the speed of queries to access the database and obtaining specific predictions. The provided study compares data mining methods, database management, and types of data. Moreover, a proposed model is introduced to put these different methods together for improving the online applications. These applications produce the ability to retrieve the information, matching keywords,
indexing database, and performing the prediction from a vast amount of data.

Salsa (20) cipher is speedier than AES cipher and its offered superior security. Salsa (8) and Salsa (12) are specified
for apps wherever the grade of security is less necessary than speed. The concept of this research is to suggest super salsa keystream utilizing various volumes matrices size (array (4, 4), array (4, 8), array (4, 16)) are used to increase the complexity of key stream and make it more reluctant to linear and differential attacks. Furthermore, in each iteration, the diffusion of generated keystream will increase due the effect of changing the volume acting for one element of the array is not fixed. The generated keys of the suggested Super SALSA keystream are depicted as simple operations and a high hardiness randomly keystream by exceeding the five benchmark tests. Likewise, it's presenting a situation of equilibrium between complexity and speed for Salsa (8, 12 and 20).

The increasing in the number of vehicles on streets has led to traffic congestion. In order to reduce the waiting time
in cases of emergency, the idea of this work is suggested. This work is divided into two parts, the particular part and software part. The first circular particular part is a model which consists of four lanes junction of a traffic light, it also has GSM system (Global System for Mobile Communications). The GSM and lamps of the traffic light are connected to Arduino UNO. The Arduino controls every signal which is coming from the inputs (GSM) to software and display to the outputs (lamps) The second circular particular part is a model which consist same components the first circuit except replace the GSM with IR(infrared Remote).The goal from this work is to help us in the emergence cases, the opening and closing of the traffic light are controlled by using GSM system and IR, the time of each lane, is controlled that means reduce the crowding.

Clinical decisions are crucial because they are related to human lives. Thus, managers and decision makers in
the clinical environment seek new solutions that can support their decisions. A clinical data warehouse (CDW) is an
important solution that is used to achieve clinical stakeholders’ goals by merging heterogeneous data sources in a central repository and using this repository to find answers related to the strategic clinical domain, thereby supporting clinical decisions. CDW implementation faces numerous obstacles, starting with the data sources and ending with the tools that view the clinical information. This paper presents a systematic overview of purpose of CDWs as well as the characteristics; requirements; data sources; extract, transform and load (ETL) process; security and privacy concerns; design approach; architecture; and challenges and difficulties related to implementing a successful CDW. PubMed and Google Scholar are used to find papers related to CDW. Among the total of 784
papers, only 42 are included in the literature review. These papers are classified based on five perspectives, namely
methodology, data, system, ETL tool and purpose, to find insights related to aspects of CDW. This review can contribute answers to questions related to CDW and provide recommendations for implementing a successful CDW.

Generally, the electronic technology has been implemented to automate the traditional systems. So, different
copy of management systems in different scope were presented.
These systems include the services provided to company as well as people, such as, healthcare. The traditional data
management systems for pharmacy as example, suffer from the capacity, time consuming, medicines accessibility,
managing the medicines store as well as the need of qualified staff according to the requirements of employer expectations. In this paper, a hospital e-pharmacy system is proposed in order to facilitate the job, outdo the mentioned problems. A data management system to the Iraqi hospital's pharmacy is proposed which is divided into two main parts: database, and Graphical User Interface (GUI) frames. The database built using SQL Server contains the pharmacy information related to the medicines, patient information….etc. the GUI frames ease the use of the proposed system by unskilled users. The proposal system is responsible on monitoring and controlling the work of pharmacy in hospital in terms of management of medicine issuing ordering and hospital reports.

All the important information is exchanged between facilities using the internet and networks, all these data should be
secret and secured probably, the personal information of person in each of these institutions day by day need to organized secretly and the need of the cryptography systems is raised which can easily encrypt the personal and critical data and it can be shared with other centers via internet without and concerns about privacy.
Chaotic performance is added to different phases of AES but very few apply it on key generation and choosing Chebyshev Polynomial will provide a chaotic map which will led to random strong key. our system based on modified advanced encryption standard (AES) , with encryption and decryption in real time taking to consideration the criticality of data images that been encrypted the main encryption algorithm is the same the modification is done by replacing the key generation algorithm by Chebyshev Polynomial to generate key with the required key size.
