The spiral model is called a meta model since it encompasses all other life cycle
models. Risk handling is inherently built into this model. The spiral model is
suitable for development of technically challenging software products that are
prone to several kinds of risks. However, this model is much more complex than
the other models - this is probably a factor deterring its use in ordinary projects.

Spiral Model is called meta model because it is composed of several other models.For example a single loop spiral actually represent the Waterfall Model.The spiral model uses prototyping approach before embarking on the actual product development effort.Also the spiral model can be considered as supporting the evolutionary model-the iterations along the spiral can be considered as evolutionary levels through which the complete system is built.This enables the developer to understand and resolve the risks at each evolutionary level.The spiral model uses prototyping as a risk reduction mechanism and also retain the systematic step approach of waterfall model.(Courtsey-Rajiv mall)

What is difference between incremental model and spiral model?
spiral model is just like incremental model but in spiral emphasize is on risk analysis.
What are data about data called?
Data about data are called metadata. See the related question "What are metadata?" for more details.
What is the difference between waterfall model iterative waterfall model successive model prototyping model and spiral model?
I will try to answer this quickly as I don't have much time. As the name suggests, the waterfall model follows the path of an waterfall. It starts in the first stage of orientation, and ends at the release. It can only go one way (to the end goal) and the stages are very strict (you cant go back to a earlier stage). The Spiral model understands that reality doesn't always follow theory, and that an project should be designed to follow that reality. There are multiple prototypes released, and phases can be repeated until the desired result is reached (hence the spiral). The iterative model combines those two, making (IMHO) the waterfall model more ready for the real world. You should try googling yourself, I found lots of info about the differences in this article about the advantages of the waterfall model: http://www.waterfall-model.com/the-waterfall-model-avantages-and-disadvantages
What is a data dictionary in software engineering?
Data dictionary is a set of meta-data which contains the definition and representation of data elements.It gives a single point of reference of data repository of an organization.Data dictionary lists all data elements but does not say anything about relationships between data elements.
Is it possible to combine the process models?
Yes it is possible to combine process models. It is the spiral process model.This model of development combines the features of the prototyping model and the waterfall model Let us consider the case study of the baggage-handling system at the Denver International Airport (DIA) again. Initially, DIA had intended that each individual airline would be responsible for building its own baggage-handling system. However, as the construction of the airport progressed, a larger vision emerged for the inclusion of an airport-wide integrated baggage-handling system that could provide a major improvement in the efficiency of luggage delivery and no one gave any thought to risk assessment. The essential concept of the Spiral Model is to minimize risks by the repeated use of prototypes and other means. Unlike other models, at every stage risk analysis is performed. The Spiral Model works by building progressively more complete versions of the software by starting at the center of the spiral and working outwards.
Why spiral model is a meta model describe it in the base of rad model?
The spiral model is called a meta model since it encloses all other life cycle model.
What is the meta model of all the models of software development life cycle?
Spiral model is called the meta model of all s/w life cycle.
Why spiral model called meta model?
The spiral model is called a meta model since it encompasses all other life cyclemodels. Risk handling is inherently built into this model. The spiral model issuitable for development of technically challenging software products that areprone to several kinds of risks. However, this model is much more complex thanthe other models - this is probably a factor deterring its use in ordinary projects.The spiral model is called a meta model since it encompasses all other life cyclemodels.

Difference between spiral model and win win spiral model?
The win-win spiral approach is very similar to the spiral model in that it is simply an extension of the spiral model. In the win-win model approach, everyone discusses things together to figure out what should go into the new version of the software.

Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
Why spiral model is called U process model?
because, there can be back process of every step in waterfall model, see the book of software engg by somerville.
What is difference between Spiral model and Prototype?
prototype model is suitable when user requirement are not very clear, while spiral model suitable for large projects whether customer requirement are not known in the beginning
Why spiral model does not contain maintenance phase?
In spiral model the main emphasis is on the management to evaluate and resolve risks in the software project. There is no maintenance phase in spiral model because instead risk is evaluated .
