1. RAD型号:
RAD模型是指快速应用程序开发,它是增量模型的类型。组件或功能是并行开发的,它可以处理小型项目以及中型项目。在此模型中,可以在任何阶段进行任何更改。由于人数较少,因此生产率很高。
2.增量模型:
增量模型是一种软件开发模型,其中对产品进行增量分析,设计,实施和测试,直到完成产品为止。发生了多个开发周期,并将这些周期划分为更多较小的模块。通常,在第一个模块期间会生产增量模型的工作软件。该模块的每个后续发行版都会在先前发行版中添加函数。在增量模型中,过程一直持续到完成整个系统为止。
RAD模型和增量模型之间的区别:
S.No. | RAD Model | Incremental Model |
---|---|---|
1. | Rad model is a software development model where by the components or functions are developed in parallel as if they were mini projects. | Incremental Model is a software development model where the product is, analyzed, designed, implemented and tested incrementally until the product is finished. |
2. | Rad model requirements and early stage planning is not necessary. | In incremental model requirements and early stage planning is necessary. |
3. | RAD model is used between large and small project. | Incremental model can’t handle large project. |
4. | There is low amount risk in RAD model. | There is also low amount risk in incremental model. |
5. | In RAD model small team size is required. | In incremental model large team is not required. |
6. | Flexibility to change in rad model is Easy. | Flexibility to change in incremental model is Easy. |
7. | In rad model overlapping of phases is possible. | In incremental model overlapping of phases is possible. |
8. | Testing is done in rad model after completion of coding. | Testing is done in incremental model after every iteration of phase. |
9. | Returning to previous stage/phase in rad model is possible. | Returning to previous stage/phase in incremental model is possible. |
10. | Cost of rad model is also Low. | Cost of incremental model is also Low. |
