“…Additionally, mostly in the Object Oriented DB context, several general approaches have been developed in order to cope with data versioning and with some of the issues related to proposal vetting (see, e.g., the survey in [27]). Recently, some object-oriented approaches also consider, besides data versioning, valid and transaction times (see, e.g., [28][29][30]). A main difference between object-oriented approaches and relational approaches has been pointed-out by Sciore [31, A few works have taken into account some form of support for alternatives within the relational context.…”

Abstract-The cooperative construction of data/knowledge bases has recently had a significant impulse (see, e.g., Wikipedia [1]). In cases in which data/knowledge quality and reliability are crucial, proposals of update/insertion/deletion need to be evaluated by experts. To the best of our knowledge, no theoretical framework has been devised to model the semantics of update proposal/evaluation in the relational context. Since time is an intrinsic part of most domains (as well as of the proposal/evaluation process itself), semantic approaches to temporal relational databases (specifically, Bitemporal Conceptual Data Model (henceforth, BCDM) [2]) are the starting point of our approach. In this paper, we propose BCDM PV , a semantic temporal relational model that extends BCDM to deal with multiple update/insertion/deletion proposals and with acceptances/rejections of proposals themselves. We propose a theoretical framework, defining the new data structures, manipulation operations and temporal relational algebra and proving some basic properties, namely that BCDM PV is a consistent extension of BCDM and that it is reducible to BCDM. These properties ensure consistency with most relational temporal database frameworks, facilitating implementations.

“…In order to extract data from a TVM base, a query language called TVQL -Temporal Versioned Query Language -was defined [26]. It is based on SQL, in a way that static elements and temporal versioned ones may be treated uniformly.…”

Temporal Versions Model (TVM) is an object-oriented data model with versioning facilities, allowing revisions and project alternatives, and temporal features, used to maintain the history of the system evolution. This paper presents TVM under a Software Configuration Management (SCM) perspective, compares this model with available SCM tools, and describes why TVM is adequate to be used as the basis of an SCM environment. A modeling example and the implementation of TVM on a commercial Database Management System (DBMS), which is an ongoing work, are also presented.
