“…Another dimension is that certain types of databases more typically afford guarantees that others do not; for example, many relational databases offer grades of ACID (Atomicity, Consistency, Isolation and Durability) guarantees [42], while few document-oriented or RDF triple stores do, partly due to technicalities arising from realising these guarantees in these settings. An additional advantage to relational databases is that extensive research on them has yielded well-known methods to "tune" performance, such as ways to factor tables to avoid otherwise computationally expensive query operations, the creation of indexes and so on, whereas such methods and query performance predictability is remains less well established for other database types.…”

This chapter argues that technical architectures that facilitate the longitudinal, decentralised and individual-centric personal collection and curation of data will be an important, but partial, response to the pressing problem of the autonomy of the data subject, and the asymmetry of power between the subject and large scale service providers/data consumers. Towards framing the scope and role of such Personal Data Stores (PDSes), the legalistic notion of personal data is examined, and it is argued that a more inclusive, intuitive notion expresses more accurately what individuals require in order to preserve their autonomy in a data-driven world of large aggregators. Six challenges towards realising the PDS vision are set out: the requirement to store data for long periods; the difficulties of managing data for individuals; the need to reconsider the regulatory basis for third-party access to data; the need to comply with international data handling standards; the need to integrate privacy-enhancing technologies; and the need to future-proof data gathering against the evolution of social norms. The open experimental PDS platform INDX is introduced and described, as a means of beginning to address at least some of these six challenges.

“…A number of FDBS transaction management algorithms have been proposed for a failure-free environment [21,9,16,3,13,18]. Recently, researchers have addressed the issue of transaction management in a failure-prone environment and a number of proposal have been made [4,25,1,12,24,20,7,26]. Each proposed recovery algorithm imposes some restrictions, which affect different aspects of local autonomy.…”

Transaction recovery in federated autonomous databases

Abstract. Transaction management for federated database systems (FDBSs), where each participating DBMS is autonomous, supports global transactions that can access more than one database. A number of concurrency control algorithms exist for the failure-free environment. Handling transaction failure, due to concurrency control or site related reasons, becomes especially difficult in the presence of autonomy. Due to local autonomy, carrying out 2-phase commit may not be possible. This can be simulated by providing a server on top of the pre-existing DBMS at each site, which is responsible for submitting the local operations to the associated DBMS and communicating with the transaction's originating site. In this paper we formalize the problem of ensuring transaction consistency in an FDBS environment in the presence of failure. The key problem is that due to autonomy, the local DBMS and FDBS may have different views of an execution sequence generated at a site. Local recoverability is identified as the property of local execution sequences necessary for correctness. The other main problem is of guaranteeing that the various locally recoverable histories are consistent with each other. These identified properties are necessary and sufficient conditions for the correctness of FDBS recovery algorithms, and can be used to evaluate the correctness of the proposed algorithms. This paper also presents an FDBS recovery algorithm that has been proved to be correct. Formal proofs of all properties and a comparison of different algorithms are provided.
