Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Software Design shopping experience:
1. Compare - without doubt the biggest advantage that the Software Design offers shoppers today is the ability to compare thousands of Software Design at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Software Design? Wrong! If the Software Design is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Software Design then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Software Design? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Software Design and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Software Design wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Software Design then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Software Design site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Software Design, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Software Design, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
Software design is a process of problem-solving and planning for a software solution. After the purpose and specifications of software is determined, software developers will design or employ
designers to develop a plan for a solution. It includes low-level component and algorithm implementation issues as well as the architectural view.
The software requirements analysis (SRA) step of a
software development process yields
specifications that are used in software engineering. If the software is "semiautomated" or
user centered design, software design may involve user experience design yielding a story board to help determine those specifications. If the software is completely
automation (meaning no user or user interface), a software design may be as simple as a
flow chart or text describing a planned sequence of events. There are also semi-formal methods like
Unified Modeling Language and
Fundamental modeling concepts. In either case some documentation of the plan is usually the product of the design.
A software design may be platform-independent model or platform-specific model, depending on the availability of the technology called for by the design.
Design Considerations
There are many aspects to consider in the design of a piece of software. The importance of each should reflect the goals the software is trying to achieve. Some of these aspects are:
- Extensibility - New capabilities can be added to the software without major changes to the underlying architecture.
- Robustness - The software is able to operate under stress or tolerate unpredictable or invalid input. For example, it can be designed with a resilience to low memory conditions.
- Reliability - The software is able to perform a required function under stated conditions for a specified period of time.
- Fault-tolerance - The software is resistant to and able to recover from component failure.
- Security - The software is able to withstand hostile acts and influences.
- Maintainability - The software can be restored to a specified condition within a specified period of time. For example, virus software may include the ability to periodically receive virus definition updates in order to maintain the software's effectiveness.
- Compatibility - The software is able to operate with other products that are designed for interoperability with another product. For example, a piece of software may be backward-compatible with an older version of itself.
- Modularity - the resulting software comprises of well defined, independent components. That leads to better maintainability. The components could be then implemented and tested in isolation before being integrated to form a desired software system. This allows division of work in a software development project.
- Reuse - the modular components designed should capture the essence of the functionality expected out of them and no more or less. This single-minded purpose render the components reusable wherever there are similar needs in other designs.
Design Patterns
A software designer or architect may identify a design problem which has been solved by others before. A template or pattern describing a solution to a common problem is known as a design pattern. (Design pattern (computer science)). The reuse of such patterns can speed up the software development process, having been tested and proved in the past.
Usage
Software design documentation may be reviewed or presented to allow constraints, specifications and even requirements to be adjusted prior to
programming. Redesign may occur after review of a programmed simulation or
prototype. It is possible to design software in the process of programming, without a plan or requirement analysis, but for more complex projects this would not be considered a professional approach. A separate design prior to programming allows for multidisciplinary designers and Subject Matter Experts (SMEs) to collaborate with highly-skilled programmers for software that is both useful and technically sound.
