In order to improve the work efficiency and reduce the cost of enterprises, the management mode of enterprise's purchase, sale and storage must be highly integrated with information technology. This system uses PHP, MySQL, Apache, Bootstrap front-end framework and other technologies to design an easy-to-operate purchase, sale and storage system, in order to achieve the systematization, standardization and automation of enterprise information management. A architecture of separation of presentation layer, business layer and data layer is realized by using ThinkPHP development framework, which is convenient for development, management and expansion.
Cloud computing attracts a large number of users by its good scalability, low cost, on-demand payment and other advantages, but due to the related technology is not mature enough, imperfect legal supervision and so on, the privacy and security problems of cloud computing are serious at present. This paper proposes a privacy data protection model based on the analysis of the security and privacy problems in cloud computing, which classifies data into private data and non-private data according to the privacy attributes of data, and considers encryption, decryption technology and data partitioning technology to protect privacy data in data transmission and data storage. Experiments indicate that this model can improve the security of privacy data to a certain degree.
Education Lecturers’ Perception and Attitude towards Massive Open Online Courses Attitude of School Administrators in Niger State, Nigeria
This study investigated the perception and attitude of education lecturers towards Massive Open Online Courses (MOOCs) in institutions of higher learning within Niger State, Nigeria. The influence of gender was also examined. The study adopted a descriptive survey design and 138 participants were selected through a multi-stage sampling technique. Four research questions and two null hypotheses guided the study, and a 14-item questionnaire was used as instrument for data collection. The questionnaire was subjected to both validation and reliability checks. Data gathered from the administration of the instrument were analyzed using Mean, Standard Deviation and t-test statistics. A decision rule was set, in which, a mean score of 3.0 and above was considered Agreed (positive perception/attitude) while a mean score below 3.0 was considered Disagreed (negative perception/attitude). Findings revealed that lecturers’ perception and attitude towards massive open online courses were positive with cumulative mean scores of 4.07 and 4.03 out of possible 5.0. Also, gender as a moderating variable, had influence on lecturers’ perception and attitude towards MOOCs. Based on these findings, it was recommended among others that education lecturers should be encouraged to participate in MOOCs in order to update their knowledge and skills. This can be achieved through the provision of enabling work environment such as internet wi-fi and learning tools that support synchronous and asynchronous online learning and by recognizing relevant certificates obtained through MOOCs during staff promotion exercise.

This study was carried out to ascertain the preparedness and attitude of school administrators in Niger State towards conduct of Senior School Certificate Examination (SSCE) in electronic mode. Descriptive survey research design was adopted and the sample for the study comprised 300 school administrators from 150 (75 public and 75 private) secondary schools in Niger State. A combination of purposive, proportionate stratified sampling and simple random sampling techniques were used to select respondents for this study. Researchers-designed questionnaire that was divided into section A, B and C was used to collect data on demographic profiles, attitude and preparedness respectively. Using Cronbach alpha formula, the reliability coefficients of the questionnaire for sections B and C were 0.89 and 0.96 respectively. The collected data were analyzed using mean, standard deviation and independent sample t-test statistics. Two research questions were answered and two null hypotheses were tested at 0.05 alpha level of significance. The results revealed that school administrators in Niger State have positive attitude towards conduct of SSCE in electronic mode, but are not fully prepared for it. It also was discovered that while attitudes of school administrators do not differ based on school type, significant difference exists in the level of preparedness for conduct of SSCE in electronic mode. Hence, it was recommended among others that appropriate governments, non-governmental agencies and school administrators should place more priority on making provision for adequate basic facilities in terms of human and materials needed for effective and efficient e-exams system particularly in the public schools.
