The Substantiator Controller gives an administrator/accountant the ability to setup up to 6 campaigns including projects and business components. Each campaign supports up to 200 employees and all campaigns can run simultaneously.


Extensions are small software programs that customize the browsing experience. They enable users to tailor Chrome functionality and behavior to individual needs or preferences. They are built on web technologies such as HTML, JavaScript, and CSS. The Substantiator is not a client server type of system, it is a distributed system, related to a Webapp in some aspects. These are some of the advantages and disadvantages of distributed systems:

Advantages

  • Resource sharing − Sharing of hardware and software resources.
  • Openness − Flexibility of using hardware and software of different vendors.
  • Concurrency − Concurrent processing to enhance performance.
  • Scalability − Increased throughput by adding new resources.
  • Fault tolerance − The ability to continue in operation after a fault has occurred.

Disadvantages

It's disadvantages are −

  • Complexity − They are more complex than centralized systems.
  • Security − More susceptible to external attack.
  • Manageability − More effort required for system management.

The developers of R&D Substantiator have attempted to attenuate these security disadvantages by relying on Google's Oauth2.
