What is the .DDB File Extension?

.DDB File Extension Description:

ProWORX Nxt is a program from Schneider Electric that is used to manage PCLs (Programmable Logic Controller). PCLs are used in the managing of automatic processes and devices. These are often used in assembly lines to manage the actions of machinery that work on the products. ProWORX Nxt is a part of the ProWORX line of software used to manage Schneider Electric's own line of PCLs. Schneider is no longer developing the program.

Files with the DDB file extension are used by ProWORX Nxt to store descriptor data. These files are used when it comes to blocking certain processes. ProWORX Nxt allows users to set parameters when it comes to the processes. The application can be used to monitor the resources and processes that are currently being run under the PCL. If the system reaches a specific limit, the application will begin blocking scheduled processes. The parameters are saved with the DDB file extension. The program monitors the system and references the files with the file extension .ddb when it senses a spike or extreme change in system resources.

The Protel 99SE program also uses the DDB file extension. Protel 99SE is used to design circuit boards for personal computers. The program is used to create designs for circuit boards. Protel 99SE also comes with the tools necessary to analyze the efficiency and benefits of the circuit board design.

The program uses the .ddb file extension to store designs. Files with the file extension DDB are actually design databases, which provide the user with storage for all the designs that have already been created as well as the designs that are already in the market. The user can refer to files with the .ddb file extension at any time.

The DDB file extension is also used by the INMOS TDS (Transputer Development System). INMOS is a company that specialized in creating chips and accessories for computers. The company developed a microprocessor called the transputer. The chip was designed to increase the capability of CPUs (Central processing Units) by acting as the building blocks for parallel computing systems. The transputer was designed to increase the system's capacity for processing simultaneous tasks.

INMOS TDS was a program released by INMOS to encourage the development of firmware and software for the transputer. Firmware handles the processes of the microprocessor without needing additional instructions from the user. The INMOS TDS application used files with the .ddb file extension in the debugging of written source code. Debugging is done to check for errors in the programming script. Users can write processes using the Occam programming language. Using the INMOS TDS debugger tool can then test source code files. The program then checks files with the .ddb file extension to test for errors. Files with the .ddb file extension store the descriptions of errors that can be found in Occam script.
