An Adaptable Ontology for Easy and Efficient University Data Management in Niger Delta University (Published)

The structure, variety and quantity of some current web content is limited in efficient exploration due to difficulty in searching and locating a specific content.  A case is the Niger Delta University where there is no unified online structure holding relevant university data. This is because there is no common data model to manage the data for which such query can easily be interpreted semantically. Therefore, this paper presents the application of semantic web technology for the unification of university data management. This research prepares the ground for the advent of software agents and other applications that require structured data for its computational processes. The ontology development follows an iterative path of the Object-Oriented System Analysis and Design (OOSAD) methodology. SPARQL was used as the query language for testing the ontology. The result is a semantically structured data that is deployable which can be expended and adapted in other institutions.

Influence of Information Literacy on the Use of Offline Database among the Undergraduate’s Students of Gombe State University (Published)

The research investigated on the influence of information literacy on the use of offline database among the Undergraduate’s students of Gombe State University. Five research objectives were formulated in the research and the literature was review according to the research questions. Mixed methods were used in the conduct of the study. A total of 363 were selected from the entire population. Two instruments were used in collecting the data which were interviewed and questionnaire and the data collected was analyzed and interpreted using a simple statistical method. The major research findings revealed that most of the students were unaware of the existence of offline database available in the University library. It also revealed that the library offers only one program on information literacy skills which were carried out once a year. It also revealed that most of the respondents do not have proper orientation programs such as seminars, training, and conferences etc. not done regularly for the students which will improve the influence information literacy and utilization of offline database available in the University library. Based on the recommendations observed by the researcher revealed that the awareness of offline databases should be made available via all necessary means in the library so that the undergraduate students will satisfy their information needs and demands. The researcher also recommends the adequate orientation programme should be adopted and conducted regularly to enable the students to be literate enough on searching for the information in need from the offline database available in the University library. The university library should be able to provide sufficient and adequate power supply. ICT’s infrastructures mad facilities together with more qualified that have the knowledge and skills in discharging their duties diligently and efficiently.

Developing an Efficient Database for Property Valuation in Anambra State, Nigeria (Published)

It has been observed that it takes quite a lot of time to carry out professional real estate valuation practice in Anambra State due to dearth of relevant property market data. This results to undue delays in execution of valuation jobs, even when information and communication technology have made things faster and easier. This has also made many a valuer to carry out property valuation without minding the authenticity and accuracy of sources of market information. Sequel to this, the study developed a database for efficient property valuation in Anambra State. Survey design was used to generate data. A market data generation form was developed in line with professional format, and was used to generate data about property type, location, structural details, condition, accommodation and use, neighbourhood characteristics, market value and date of property transaction. The form aided in developing the database of market transactions in the study area using MySQL (My Structured Query Language) database software package .The result of the study showed that the causes of inaccessibility to property market data are lack of organized records, lack of regular market surveys, use of traditional filing systems and non use of computer technology. Similarly, the research proved that the use of MySQL database system can indeed ensure speed and accuracy of valuation exercises and reliability of valuation figures and opinions. Finally, a customized functional property market database was developed; and the database can be accessed on www.anambrapropertydatabase.com.The study, therefore, recommended that the database should be commercialized. Further studies should be carried out to include specialized properties in the development of this database in the area.

Awareness and Utilization of Databases Subscribed to by FUTO Library among FUTO Academic Staff (Published)

This paper is an attempt to study the issues of database Awareness and utilization by Academic Staff members in Federal University of Technology, Owerri with a view to study the exposure of Academics staff to the University’s subscribed database resources. It also aims to bring to light the challenges that confront the users and recommend some remedial measures for its improvement. A test-retest reliability method of two weeks interval was conducted, response obtained were subjected to Pearson Product Moment Correlation method and a reliability co-efficient of 0.78 was obtained. The Random Sampling Technique together with a Questionnaire was used for data collection on 100 out of a population size of 1,003 academic staff members and only 74 responded giving a response rate of 74 percent.Descriptive and inferential Statistics including Frequencies count, charts, mean score, Relative Important index (R.I.I) and Percentages were used in reporting the findings. The study confirmed that the level of awareness of the subscribed electronic information resources or databases by the Library Management is rather low as well as that of the level of utilization. The paper records that the reasons why academic staff members of the Federal University of Technology, Owerri use databases; were mainly for research (48%) and current awareness (49%). It suggests further for an improvement in the training of the academic staff members , efficient power supply, and access to facilities with high Internet speed and subscription to more databases (e-resources) by the University Library.
