The Impact

Databases are an important part of today’s applications where large amounts of data need to be stored, processed, and accessed quickly. One of the important criteria when choosing to use a database technology is its data processing performance. In this paper, some methods for optimizing the database structure and queries were applied on two popular open-source database management systems: MySQL as a relational DBMS, and document-based MySQL as a non-relational DBMS. The main objective of this paper was to conduct a comparative analysis of the impact that the proposed optimization methods have on each specific DBMS when carrying out CRUD (CREATE, READ, UPDATE, DELETE) requests. To perform the analysis and performance evaluation of CRUD operations for different amounts of data, a case study testing architecture based on Java was developed and used to show how the databases’ proposed optimization methods can influence the performance of the application, and to highlight the differences in response time and complexity. The results obtained show the degree to which the proposed optimization methods contributed to the application’s performance improvement in the case of both databases; based on these, a detailed analysis and several conclusions are presented to support a decision for choosing a specific approach.

Bojanala Platinum District Municipality (BPDM), in the North West Province is endowed with the extractive economy. The District experiences challenges of capacity development of service delivery structures and programmes. It is in this context that this paper explains how local government responses to challenges of capacity development in the District Municipality. In addition, the paper explores ways in which they can be overcome for enhanced service delivery. The purpose of this study is to examine challenges related to the use of capacity development structures and programmes related to service delivery and explores how to overcome them. The study examines the structures and programmes, facilitators and inhibitors of skills development and performance initiatives within the context of local government capacity development. This study develops a theoretical framing incorporating scholarship on human capital and performance improvement in the context of local government. This framing is premised on the scholarly evidence that capacity development is an enabler of service delivery, influenced by skills development and municipal performance improvement. The research is a single case qualitative case study approach and employs an interpretative paradigm. The paper employs senior managers in the municipalities as the unit of analysis. That study reveals that there are difficulties associated with skills retention and organisational relations. In conclusion, political abandonment, poor communication and stakeholder engagements contribute to weakened inter-municipal co-operation and inadequate use of resources. The interface between learning and skills development contributes to the body knowledge.

Current Experience

In the era of globalization and borderless economies, performance improvement is not an option. It is a must for enhancing government's global competitiveness. Quality and performance of government employees need substantial improvement. In that regard, this study focuses on how performance-related pay (PRP) strategies strengthen the pay-performance link. Establishing PRP programs in government seems to be a good idea, but the Korean government's current experience with PRP shows a number of limitations. Recently, PRP and performance measures faced serious criticism from government employees for various reasons. PRP and performance measures must be improved in order to alleviate complaints and dissatisfaction. Cultural transformation, in particular, must occur for successful implementation of PRP measures.
