....consist of record types related by one to many relationships. A stricter version of the network model is the hierarchical model where record types are organized in a tree like structure. An important step in providing more exibility and physical data independence was the introduction by Codd [8] of the relational data model, by far the most popular database model in use. The relational model is simple and elegant with sound underlying theory based on concepts of relational algebra and rst order predicate calculus. The most important research e orts that emerged in commercial products ....

....in the broad area of automata and logic which are motivated by the advent of XML. In particular, we consider unranked tree automata, tree walking automata, and automata over infinite alphabets. We focus on their connection with logic and on questions imposed by XML. 1 Introduction Since Codd [11], databases have been modeled as first order relational structures and database queries as mappings from relational structures to relational structures. It is, hence, not surprising that there is an intimate connection between database theory and (finite) model theory [58, 60] As argued by ....

....aborted . It is the responsibility of the On Line Transaction Processing Systems (OLTP) used in the business applications to guarantee these requirements of transaction atomicity. For more than two decades, both industry and research community have been showing great interest in OLTP systems [Cod70, EGLT76, LS76, Gra78, Sto79, ML83, MSF83, MLO86, MBCS92, MHL 92, MN94, Moh93, WDH 82, SKPO88, FZT 92, She93, DGS 90, SJR91, WD95] The two concepts that have revolutionized the OLTP technology are the Relational Model and the Transaction Model .

Relational Model [Cod70] paved the way for the formalization of the database systems, providing a solid theoretical foundation a very important prerequisite for the proper understanding of any system. Transaction Model [Gra78, Gra81] formalized the notions of database consistency and transaction atomicity, making ....
