The func_ref expression evaluates to a (generic or specific) function identifier, which may be the same as the function that the expression is a part of, thus allowing recursive function invocations. The expression labelled arg evaluates to an arbitrary object or aggregate object. The semantics of evaluating function applications was discussed in detail in section 2. For example, to set the name of a person, we evaluate the following expression FunAssign(function name.person) (p1,'John') In this example, the first expression is itself a function call, applying the function FunAssign to the function name.person (an example of a specific function reference). This returns the oid of the function that sets a person's name, which is subsequently applied to a tuple of two elements, the oid of the person and the new name (a string o...

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 application/pdf text http //citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.33.8596 http //www.edbt2000.uni-konstanz.de/phd-workshop/papers/Josinski.pdf en 10.1.1.27.4704 10.1.1.51.8352 Metadata may be used without restrictions as long as the oai identifier remains attached to it." } }

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...

The func_ref expression evaluates to a (generic or specific) function identifier, which may be the same as the function that the expression is a part of, thus allowing recursive function invocations. The expression labelled arg evaluates to an arbitrary object or aggregate object. The semantics of evaluating function applications was discussed in detail in section 2. For example, to set the name of a person, we evaluate the following expression FunAssign(function name.person) (p1,'John') In this example, the first expression is itself a function call, applying the function FunAssign to the function name.person (an example of a specific function reference). This returns the oid of the function that sets a person's name, which is subsequently applied to a tuple of two elements, the oid of the person and the new name (a string o...

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 application/pdf text http //citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.33.8596 http //www.edbt2000.uni-konstanz.de/phd-workshop/papers/Josinski.pdf en 10.1.1.27.4704 10.1.1.51.8352 Metadata may be used without restrictions as long as the oai identifier remains attached to it." } }

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...

The func_ref expression evaluates to a (generic or specific) function identifier, which may be the same as the function that the expression is a part of, thus allowing recursive function invocations. The expression labelled arg evaluates to an arbitrary object or aggregate object. The semantics of evaluating function applications was discussed in detail in section 2. For example, to set the name of a person, we evaluate the following expression FunAssign(function name.person) (p1,'John') In this example, the first expression is itself a function call, applying the function FunAssign to the function name.person (an example of a specific function reference). This returns the oid of the function that sets a person's name, which is subsequently applied to a tuple of two elements, the oid of the person and the new name (a string o...

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...

In such a system, global transactions are executed under the control of the MDBS. Independently, local transactions are executed under the control of the local DBMSs. Each local DBMS integrated by the MDBS may employ a different transaction management scheme. In addition, each local DBMS has complete control over all transactions (global and local) executing at its site, including the ability to abort at any point any of the transactions executing at its site. Typically, no design or internal DBMS structure changes are allowed in order to accommodate the MDBS.

In addition, a database system with rule processing capabilities provides a useful platform for large and efficient knowledge-base and expert systems. Database systems with production rules are referred to as active database systems, and the field of active database systems has indeed been active. This chapter summarizes current work in active database systems topics covered include active database rule models and languages, rule execution semantics, and implementation issues. 1 Introduction Conventional database systems are passive they only execute queries or transactions explicitly submitted by a user or an application program.

In addition, a database system with rule processing capabilities provides a useful platform for large and efficient knowledge-base and expert systems. Database systems with production rules are referred to as active database systems, and the field of active database systems has indeed been active. This chapter summarizes current work in active database systems topics covered include active database rule models and languages, rule execution semantics, and implementation issues. 1 Introduction Conventional database systems are passive they only execute queries or transactions explicitly submitted by a user or an application program.

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...

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 application/pdf text http //citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.33.8596 http //www.edbt2000.uni-konstanz.de/phd-workshop/papers/Josinski.pdf en 10.1.1.27.4704 10.1.1.51.8352 Metadata may be used without restrictions as long as the oai identifier remains attached to it." } }
