Introduction  The multidatabase system (MDBS) approach, as a solution for 
integrated access to information distributed among diverse data sources, has 
gained a lot of attention in recent years. The multidatabase system is a 
database system which integrates pre--existing databases allowing the users to 
access simultaneously database systems (DBMSs) formulating a global query based 
on a global schema.  The component DBMSs are assumed to be heterogeneous and 
autonomous. Heterogeneity refers to different user interfaces, data models, 
query
  languages, and query optimization strategies [5]. Local autonomy means that 
each DBMS retains complete control over local data and processing. As result of 
this, its cost model may not be available to the global query optimizer.  When 
a global query is submitted, it is decomposed into two types of queries [1]   
-- subqueries, operating on sharable data items from local databases,  -- 
assembling queries, consisting of, CiteSeerX  2009-04-15 2007-11-22 2000

Workflows are activities involving the coordinated execution of multiple tasks 
performed by different processing entities. A task defines some work to be done 
and can be specified in a number of ways, including a textual description in a 
file or an email, a form, a message, or a computer program. A processing entity 
that performs the tasks may be a person or a software system (e.g., a mailer,

Introduction  The multidatabase system (MDBS) approach, as a solution for 
integrated access to information distributed among diverse data sources, has 
gained a lot of attention in recent years. The multidatabase system is a 
database system which integrates pre--existing databases allowing the users to 
access simultaneously database systems (DBMSs) formulating a global query based 
on a global schema.  The component DBMSs are assumed to be heterogeneous and 
autonomous. Heterogeneity refers to different user interfaces, data models, 
query
  languages, and query optimization strategies [5]. Local autonomy means that 
each DBMS retains complete control over local data and processing. As result of 
this, its cost model may not be available to the global query optimizer.  When 
a global query is submitted, it is decomposed into two types of queries [1]   
-- subqueries, operating on sharable data items from local databases,  -- 
assembling queries, consisting of, CiteSeerX  2009-04-15 2007-11-22 2000

Workflows are activities involving the coordinated execution of multiple tasks 
performed by different processing entities. A task defines some work to be done 
and can be specified in a number of ways, including a textual description in a 
file or an email, a form, a message, or a computer program. A processing entity 
that performs the tasks may be a person or a software system (e.g., a mailer,

Introduction  The multidatabase system (MDBS) approach, as a solution for 
integrated access to information distributed among diverse data sources, has 
gained a lot of attention in recent years. The multidatabase system is a 
database system which integrates pre--existing databases allowing the users to 
access simultaneously database systems (DBMSs) formulating a global query based 
on a global schema.  The component DBMSs are assumed to be heterogeneous and 
autonomous. Heterogeneity refers to different user interfaces, data models, 
query
  languages, and query optimization strategies [5]. Local autonomy means that 
each DBMS retains complete control over local data and processing. As result of 
this, its cost model may not be available to the global query optimizer.  When 
a global query is submitted, it is decomposed into two types of queries [1]

Sheth", "misc": "2009-04-13 The basic transaction model has evolved over time 
to incorporate more complex transaction structures  and to selectively modify 
the atomicity and isolation properties. In this chapter we discuss the 
application  of transaction concepts to activities that involve coordinated 
execution of multiple tasks (possibly of  different types) over different 
processing entities. Such applications are referred to as transactional  
workflows. In this chapter we discuss the specification of such workflows
  and the issues involved in their  execution.  1 What is a Workflow?  
Workflows are activities involving the coordinated execution of multiple tasks 
performed by different processing entities. A task defines some work to be done 
and can be specified in a number of ways, including a textual description in a 
file or an email, a form, a message, or a computer program. A processing entity 
that performs the tasks may be a person or a software system (e.g., a mailer, 
an application program, a database mana... CiteSeerX ACM Press 2009-04-13
