Synthesizing b specifications from EB3 attribute definitions

EB^3 is a trace-based formal language created for the specification of information systems (IS). Attributes, linked to entities and associations of an IS, are computed in EB^3 by recursive functions on the valid traces of the system. We aim at synthesizing relational database transactions that correspond to EB^3 attribute definitions. Each EB3 action is translated into a transaction. EB^3 attribute definitions are analysed to determine the key values affected by each action. Some key values are retrieved from SELECT statements that correspond to first-order predicates in EB^3 attribute definitions. To avoid problems with the sequencing of SQL statements in the transactions, temporary variables and/or tables are introduced for these key values. Generation of DELETE statements is straightforward, but distinguishing updates from insertions of tuples requires more analysis.
