The need for a robust system architecture to support software development is well known. In enterprise software development, this must be realized in a multi-tier environment for deployment to a software framework. Many popular integrated development environment (IDE) tools for component-based frameworks push multi-tier partitioning by assisting developers with convenient code generation tools and software deployment tools which package the code. However, if components are not packaged wisely, modifying and adding components becomes difficult and expensive. To help manage change, vertical partitioning can be applied to compartmentalize components according to function and role, resulting in a grid partitioning. This thesis is to advocate a design methodology that enforces vertical partitioning on top of the horizontal multitier partitioning, and to provide guidelines that document the grid partitioning realization in enterprise software development processes as applied in the J2EE framework.

Companies are looking for ways to improve their business practices to work more efficiently.They are also looking for technology that can improve their workflows and customer service systems.  Here comes the need of enterprise software applications, theses softwares allows companies to cut costs and standardize the way they work, ensuring that everyone is working towards the same goal. The objective of this study is an assignment from Ericsson Business Support Solutions with the purpose of studying the effect of transitioning from the currently used process (CSV files) to an interactive web UI, when it comes to the process of handling offering of software capabilities.In this study, we aim to study the challenges and opportunities of developing an enterprise application software(EAS) and its impact on the productivity of end users.This research will also study the challenges and benefits of developing an enterprise software application (Digital marketplace) that will be used in a large (+500 employees) organization. In addition, the study will research security aspects that should be considered when developing enterprise softwares. Two sorts of studies have been conducted to answer the research questions. In order to understand and gain knowledge about the process of enterprise software development and to be able to point out which challenges and benefits there are and to get closer view of which security aspects should be in consideration when developing a software on this scale, a literature study was conducted. In order to observe and investigate whether web interfaces are a better solution / method than CSV files, and thus see the possibility of whether web interfaces can generally replace CSV files when it comes to CRUD, search and filtering information an empirical study was carried out through the development of a user interface and a usability test survey was conducted. The overall results of the study consistently show that UI is a more resourceful alternate to the  CSV files if the challenges posed by the enterprise software are sufficiently engaged and taken care of. A solid insight and expertise into information technology, pragmatic solutions to the security challenges, and careful consideration of the participants' complaints will be helpful in creating functional enterprise software.
