Change Management Systems or a version control mechanism is the pillar stone of success for any software development effort. Rapid changes and concurrent streams of development due to business complexity, legal, or any other reason needs the best version control mechanism to manage these changes. Business changes more often than not results in modifications for the underlying database system as that is where the data is stored. Very few organizations realize that how difficult it is to undo a database change in a relational database management system (RDBMS) [1]. If by mistake an incorrect version of the application code is deployed, the correct version can be re-deployed and for the most part, everything will be fine. Whereas incorrect database change can be destructive, incur partial data loss to a complete data loss, or even result in database restore. That is a huge cost to pay in absence of effective change management system. In today’s software organizations, time-to-market is paramount [2]. To achieve this, organizations develop software in a highly aggressive schedule with multiple streams (or releases) being worked upon concurrently. This provides a huge challenge to ensure that only the exact change(s) are deployed in various Development, Test, Performance, Pre-Production, and Production environment. This is where a Database Change Management System can help and this document explains exactly how that can be done.

SAP HANA is an in-memory, column based, relational database management system (RDBMS) created and showcased by SAP. It's essential capacity as database server is to store and recover information as requested by the applications. Moreover, it performs advanced analytics (spatial data processing, predictive analytics, streaming analytics, graph data processing, text analytics, text search) and includes ETL capabilities as well as an application server. The key distinctions between HANA and previous generation SAP systems are that it is an in-memory, column based database that combines OLAP and OLTP operations into a single system. Storing data in main memory rather on disk provides faster data access and, by extension, faster querying and processing. This article aims at explaining what SAP HANA Express Edition is and how it can be implemented using Google Cloud Platform.

This qualitative case study elicits personal attributes of applicants who wish to enroll in the Program for Excellent Student-Teachers in colleges of education in Israel. As a democracy, which bases its education system on democratic values, Israel considers itself as part of the Western world. A set of qualitative tools and methodology were used to elicit each individual's personal attributes and to determine their strength. Tools that are currently in use, which are based on the existing standardized tools that focus mainly on cognitive competencies, do not supply a sufficiently detailed foundation to differentiate between applicants. When tools are interesting, meaningful, and taken from real life, tacit knowledge is easily revealed. Applicants in this study document their reflection and their academic, vocational, or personal growth as a major part of the raw data for analysis. The study included 68 participants aged 20−25. The model presenting detailed differentiation between individuals is the major theoretical contribution of this study. The practical contribution of this study is the positive impact that these students had on the climate of teaching and learning in the college and the absorption of excellent teachers to enhance the teaching force. These procedures can easily be applied by teacher education faculty members.

It is no longer news that the standard of education in the third world countries is fast falling. Nigeria is not an exception. This may not be unconnected with human factors, infrastructural decay and government lackadaisical attitude in tackling the problems in the education sector. Many universities especially the recently established ones can boast of very view experienced lecturers. The economic crisis in the country coupled with poor remuneration for teachers has contributed in no small measure to brain drain in the system. The challenge therefore is to optimize the little ‘brain’ that is left for the benefit of all students across the whole countries as opposed to the current trend of localizing the lecturers. This paper discusses e-learning, it examine the challenges and prospect of e-learning paradigm and propose integrated e-learning system architecture for the purpose of sharing the knowledge of few experts and professional still remaining in the universities system.

Road accident is a special case of trauma that constitutes a major cause of disability, untimely death and loss of loved ones as well as family bread winners. Therefore, predicting the likelihood of road accident on high ways with particular emphasis on Lagos – Ibadan express road, Nigeria in order to prevent accident is very important. Various attempts had been made to identify the cause(s) of accidents on highways using different techniques and system and to reduce accident on the roads but the rate of accident keep on increasing. In this study, the various techniques used to analyse the causes of accidents along this route and the effects of accidents were examined. A technique of using data mining tool to predict the likely occurrence of accident on highways, the likely cause of the accident and accident prone locations was proposed using Lagos –Ibadan highway as a case study. WEKA software was used to analyse accident data gathered along this road. The results showed that causes of accidents, specific time/condition that could trigger accident and accident prone areas could be effectively identified.

In this paper, our research objective is to develop a database virtualization technique in order to let data analysts or other users who apply data mining methods to their jobs use all ubiquitous databases on the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet databases and data cleansing works. In this study, firstly we examine XML schema advantages and propose a database virtualization method by which such ubiquitous databases as relational databases, object-oriented databases, and XML databases are accessed as if they all behave as a single database. Then, we show the method of virtualization of ubiquitous databases that can describe ubiquitous database schema in a unified fashion using the XML schema. It consists of a high-level concept of distributed database management of the same type and of different types, and also of a location transparency feature. Next, we discuss about the development of a common schema generation method and propose the virtual database query language for use in the virtualized ubiquitous database environment. Finally, we propose a database incompatibility trouble-recovery technique for use in a virtualized ubiquitous database environment.

A cancer registry is an important program component for the evaluation of cancer care. Accurate and timely collection of cancer patient data with appropriate follow-up is required by the Commission on Cancer. electronic medical information system (EMIS) and medical database (MDB) as basises for health service planning and resource allocation are vital importance in settings with limitted resources. Whether the data is collected on paper or electronically does not matter at the end important is the involvment of the staff responsible for its collection and the tangible benefits for the health professionals. This paper present Spatial Information System (SIS) for cancer patients' registry in Egypt which will be very important from the reference and legal point of views for the consultant and administration and also will play vital role in treatment, follow up, medical researches and statistical reports in hospitals.

It is clear that in today’s organizations, new and existing applications require access to data stored in several pre-existing databases held at several local and remote locations. Therefore, a main criterion required by most complex organizations, is the provision of collaboration possibilities and information integration mechanisms among distributed, heterogeneous, and autonomous database systems. The development of an application provides interoperability and information integration among distributed systems, via the deployment of database standards and emerging Internet technologies. It is one of the most challenging approaches in the area of integrating heterogeneous information from autonomous sites. In this context, the work described in this paper focuses on the design and development of a Generic Information Exchange (GIE) System. The system supports a wide variety of applications with efficient means for their interconnection and interoperation, while preserving their heterogeneity, distribution, and full autonomy. An example of the interoperability problem is found in the healthcare domain, where each hospital, or even each department in a hospital, maintains its own database. In this environment it is very important to permit users to locate and access data from several remote databases, supporting the needs of patient care, daily operations of the hospitals and research consultations. It necessitates the sharing and exchange of data related to clinical, administrative, managerial and research (statistical) information.
