The first step to thoroughly understanding the Pathmaker product, is to understand
the purpose of the product and how it works with other Tandem products. This
section addresses these issues by:
Introducing some of the benefits and features of the Pathmaker product.
Describing online transaction processing (OLTP) applications.
Discussing some of the benefits and features of the Pathway product and
introducing Pathway terminology.
Describing the main purpose of several related Tandem products including
NonStop SQL, Enscribe, Enscribe Data Definition Language (DDL), and the
Transaction Monitoring Facility (TMF) product.
Overview of
Pathmaker
The Pathmaker product is a tool that assists in the creation of Pathway requester-
server applications for computer systems that use the Tandem NonStop Kernel. These
applications require the full support of all Tandem features such as fault tolerance,
linear expandability, security, data integrity, and high performance.
The Pathmaker product can improve the productivity of professional application
developers by removing many of the labor-intensive coding tasks associated with
creating an application. Applications created with the Pathmaker product can access
data from NonStop SQL and Enscribe databases.
Benefits of Using
Pathmaker
Some of the benefits gained by using the Pathmaker product include:
Shorter development time for online transaction processing (OLTP) applications.
Shorter maintenance time for OLTP applications.
More application developers without Pathway experience are able to code
Pathway programs because the Pathmaker product generates the program
statements specific to Pathway applications.
A unified application development environment.
Improved project control because the components of an application are stored in a
central location.
Significant end user input allowed prior to coding.
Support for the development of a wide range of applications.
Production of Pathway applications that utilize the full power of the Tandem
multiprocessor system architecture.
Note The Pathmaker product is not a fourth generation language or tool for developing decision-support
applications that do not require the Tandem fundamentals.
