A.: Using Goals and Quality Models to Support the Matching Analysis During COTS Selection

Abstract. The selection process is a crucial activity of the development of COTS-based systems. A key step of the evaluation of COTS components carried out during selection is the matching between user requirements and COTS features. We propose a goal-based approach to guide the matching process, using quality models for leveraging goals and COTS features. The different mismatch situations that may arise are reasoned by means of exploratory scenarios. We demonstrate the approach with the mail server case study.

Domain Analysis for Supporting Commercial Off-The-Shelf Components Selection

Abstract. Though new technological trends and paradigms arise for developing complex software systems, systematic reuse continues to be an elusive goal. In this context, the adoption of Commercial Off-The-Shelf (COTS) technologies introduces many challenges that still have not been fully overcome, such as the lack of comprehensive mechanisms to record and manage the required information for supporting COTS components selection. In this paper we present a domain analysis approach for gathering the information needed to describe COTS market segments as required for effective COTS components selection. Due to the diversity of the information to capture, we propose different dimensions of interest for COTS components selection that are covered by different domain models. These models are articulated by means of a single framework based on a widespread software quality standard.

A 2,3-butanedione protected chiral glycine equivalent - A new building block for the stereoselective synthesis of enantiopure N-protected α-amino acids

A new chiral glycine equivalent 7 has been synthesised from glycidol using a chiral memory protocol, and its use in the synthesis of N-Z protected alpha-amino acids was demonstrated in a series of diasteroselective lithium enolate alkylation reactions and subsequent acid hydrolyses
