Define Monolithic Architecture.
A traditional software development model that uses one code base to perform multiple business functions.
What is Layered Architecture?
Each layer provides specific functionalities and services to the layers above it.
Layered Architecture is good for which scenarios?
- Demand maintainability
- Budget constraints
- Small and simple applications
What does Pipeline Architecture structure?
Structures the processing of data or tasks as a series of connected processing stages.
What is the role of Pipes in Pipeline Architecture?
- Form the communication channel between filters
- Typically unidirectional and point-to-point between filters
- Payload may contain any data structure, but small amounts are favored
What are Filters in Pipeline Architecture?
- Self-contained
- Independent from other filters
- Generally stateless
- Should perform one task only
- Composite tasks should be handled by a sequence of filters
What is the function of a Producer in Pipeline Architecture?
The starting point of a process, outbound only, sometimes called the source.
What does a Transformer do in Pipeline Architecture?
Accepts input, optionally performs transformation on some or all of the data, then forwards it to the outbound pipe.
True or False: A Tester in Pipeline Architecture accepts input and tests one or more criteria.
True
What is the role of a Consumer in Pipeline Architecture?
The termination point for the pipeline flow, sometimes persisting the final result to a database or displaying results on a user interface.
