Introduction

Living in the era of computer technology, the information storage techniques are aimed at easy accessing and utilizing data at an external level. Thereby, library and information science has expanded their studies and has included the analysis of database management.

There are different approaches for retrieving and storing information in the database: hierarchical, relational, and network models that represent information to the users, particularly to students and school librarians. Significant contribution in the database management is increasing access to full-text databases.

Due to the fact that demand for such services has considerably increased as the information is constantly growing, it is often difficult to define which techniques are applicable to a learning process and, what is more important, to the improvement of school librarians’ access to magazine indexes.

Research Question

An access to information is ensured by specific models of database systems. This model is defined by modeling language that determines the schema for hosting each database in the DBMS. Therefore, in this scientific paper, we seek to determine which approaches foster the process of database search of online libraries and catalogues, which is of great value for an academic process.

Due to the fact that the relational database model is considered to be prevailing, it is still necessary to consider the recent techniques and strategies of information retrieval in accordance with the type of index searching and information processing.

Literature Review

Defining the terms

Panneerselvam distinguishes three basic data models: hierarchical, relational, and network (67). Hence, the first model “consists of a set of nested relationships having one-to-many (1: M) and one-to-one (1:1) associations” (67). The second approach consists in using two-dimensional tables providing data in the form of highly discipline files (Pannerselam 71).

Finally, the third model is represented through a set of files and polar associations between the files. It refer to many accesses and records and, therefore, the model is based on many-to-many (M: M) relationships.

Kedar provides a more expanded variant of database models. Beside the above-presented models, the scholar singles out entity relationship model and object model (2-1).

Hence, entity relationship model is based on defining the set of entities or one entity serving as a key component in the searching process. It can refer to people and books. In contrast, object model allows users to handle pictures, graphics, and text, which is especially important due to the rapid technological expansion and assignment sophistication.

Historical overview

The first experience of database application was acquired by large corporations, hospitals, universities, and banks (Bangia18). These institutions deal with large amounts of information, including records and documentation that should be properly stored. While using hierarchical and network models, the major problems were connected with confusing physical storage and conceptional relationships.

In particular, the models failed to provide sufficient flexibility to access the information when new requests were identified. In order to solve this problem, relational and object model were designed that successful eliminated the previously emerging problems (Bengia 19). Currently, the models are being constantly updated through the introduction of new platforms and applications (Kothuri, Godfrind, and Beinat 4).

Based on the above-presented considerations, the significance of the full-text databases consist in increasing efficiency of books and articles retrieval with the help of indexes is crucial.

In particular, Pastine states that the search for articles and other important resources may “involve an additional step – locating the needed journal through another index that lists the periodicals and their holdings that are located in the library” (215). Such a complicated process provides significant difficulties in utilizing database systems.

Methodology

In order to efficiently estimate various models of database management, it is necessary to apply to a combination of qualitative and qualitative analysis of organizations’ proficiency.

Specifically, it is possible to carry out the research on educational establishment and libraries to define what database models they use and how effectively they implement search with the help of indexes. The research will focus on two types of organizations: library and university to pursue the advantages and limitations to using a particular database model and search techniques.

The quantitative analysis will involve the survey of libraries, and universities using various approaches to database management. The information obtained from the survey will help compile statistics and define the prevailing models used in the establishments. Numerical data can also be used to defining the least applied methods.

Results and Evaluation

The analysis of qualitative and quantitative characteristics of database models has revealed that the object-oriented model is the easiest one in providing the most accurate results of the search.

Due to this fact that this model is based on searching for images, books, and graphics, it can help students and librarians to search for computer data and digital information, which is impossible without those techniques. Such strategies are also crucial for those students whose specialization is computer graphics, design, or engineering, although other disciplines will also benefit from using this model.

Limitations to the research

In spite of the fact that rapid development of communication network and online search, database management still fails to receive sufficient attention.

In this regard, the research under considerations can have serious difficulties in exploring network management functions and resources needed to access the information. Therefore, school librarians should focus their attention on the fact that online library catalogues still lack sophistication.

Conclusion

The value of the research consists in presenting new techniques and innovation in the sphere of library science that is of great importance for educational and training purposes. In particular, the research proposal will contribute to better and more flexible information organization.

More importantly, the research will help students and school librarians to access and retrieve information with the help of indices. Further researchers should be dedicated to the exploration of more efficient techniques of information organization and security.
