Experiences in the Implementation of a Process-centered Software Engineering Environment using Object-Oriented Technology
No full textSoftware engineering environments (SEEs) pose complex and critical requirements to the supporting repositories. Object-oriented Database Management Systems (ODBMSs) are expected to provide suitable features to successfully address these issues. SPADE is a process-centered SEE being developed at CE-FRIEL and Politecnico di Milano. SPADE is built on top of an OODBMS and features process modeling and enactment, management of process data and facilities to integrate development tools. This paper reports the experiences gained by the authors in defining the requirements for SPADE’s process data repository, and in assessing six different OODBMSs against these requirements. The assessment has been carried out through several prototypes and within the context of the ESPRIT project GoodStep
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The architecture of the SPADE-1 Process-Centered SEE
No full textSPADE is a project carried out at CEFRIEL and Politecnico di Milano. It aims at defining a process modeling language (called SLANG) and a Process-centered Software Engineering Environment (PSEE) based on this language. PSEEs support software activities through the execution of the model of the software process. Such a model integrates the description of human activities and of the interaction between humans and software development tools. Moreover, PSEEs must provide the means to manage and persistently store the artifacts developed within the process. SPADE-1 is an implementation of the SPADE concept. In particular, it includes a SLANG interpreter and facilities to store process artifacts in an object-oriented database (O2), and to interface the process interpreter with an integrated tool environment (DEC FUSE). This paper summarizes the architectural requirements derived from SPADE and provides a description of the SPADE-1 prototype
