“…The ORDB core data model represents objects as relational tables. Thus designers can use SQL-based data definition language to represent object-oriented concepts in ORDB (Krishnamurthy, 1999). The ORDB concepts, like abstraction, encapsulation, inheritance, and polymorphism, are inherited from the object-oriented concepts.…”

Purpose The purpose of this paper is to present an innovative agile methodology that proposes fundamental changes in managing the development of in-house information systems in small- and medium-sized enterprises (SMEs) and benchmarks it with one of two database technologies enabling these systems to be both efficient and competitive. Design/methodology/approach The objectives are achieved by presenting an elaborated design of the agile methodology that manages the system development process by addressing three basic components: roles played by system players, process needed to fulfill the system development, and artifacts to document the project. A case study is conducted as a proof of the effectiveness of the proposed methodology and measures whether the selection of the database technology affects the effectiveness of the system development process. Findings Results show that, compared with traditional methodologies, the proposed methodology reduced the cost of system development and testing by 30 percent and enhanced the IT – business alliance. Further, this work found that the selection of a suitable database technology is strongly related to the complexity and interrelationships between the data used. Originality/value Such research did not receive the needed attention (Hunter, 2004) even in the past decade. Successful adoption of IT by companies could be in the form of customized IS which could be expensive for SMEs to adopt due to a lack in technical expertise and financial resources. The proposed methodology has the potential to promote sustainable development through helping SMEs in reducing the time and cost of IT project development.

Commercial database management systems (DBMSs) have historically seen very limited use within the scientific computing community. One reason for this absence is that previous database systems lacked support for the extensible data structures and performance features required within a high-performance computing context. However, database vendors have recently enhanced the functionality of their systems by adding object extensions to the relational engine. In principle, these extensions allow for the representation of a rich collection of scientific datatypes and common statistical operations. Utilizing these new extensions, this paper presents a study of the suitability of incorporating two popular scientific formats, NetCDF and HDF, into an object-relational system. To assess the performance of the database approach, a series of solution variables from a regional weather forecast model are used to build representative small, medium and large databases. Common statistical operations and array element queries are then performed using the object-relational database, and the execution timings are compared against native NetCDF and HDF operations.
