In the modern world there is almost no website left constructed on static contents. The vast majority of web pages is generated dynamically on server side. As a rule, creation of the web page happens by means of different execution of scripts. It provides simplicity of development and modification of the website. Evolution of web development led to emergence of CMS giving to the web master almost everything that it is necessary for creation of a resource. However there are not always enough CMS opportunities. Therefore it is necessary to write scripts for the website still sometimes.
It is required to you
- - specialized development environment or the editor with syntax highlighting;
- - Internet access;
- - modern browser.
Instruction
1. Plan functionality of future script. Accurately answer questions of what it will intend for what will solve problems and what this to process. Record requirements to a script in the form of the simple list of theses.
2. Think over architecture of a script. If the script is rather difficult, it is necessary to be predeterminated with the choice of its structure, approaches to the organization of storage, processing and data exchange. Also it makes sense to study existing solutions.
3. Select technologies by means of which the main functionality of a script will be implemented. Select a programming language, technologies of storage (DBMS, file formats) and special processing (graphic, cryptographic and other libraries) of data.
4. Study the manuals and documentation on the technologies and products selected the third step. Answer a question of expediency of application of a separate product or technology. If it is necessary, correct the list of technologies, having found acceptable alternatives.
5. Make the technical development plan of a script. Even if it seems that development process will be rather simple, following to the accurate plan will allow to save considerable amount of time and will increase efficiency of work. If it is planned to create a difficult script, then at the initial stage it makes sense to make the plan of implementation of its framework with the minimum functionality (the majority of the code can be replaced with stubs).
6. Implement a part of functionality of a script according to the plan developed on the previous step.
7. Make testing of a script. You enter the revealed errors in the special list. View the list of errors and assign by it priority indicators according to which they will improve. Sort the list of errors on the basis of priority indicators.
8. Correct the errors found at the previous stage.
9. Consider need of further work on a script. For this purpose analyze compliance of the current characteristics to the planned functionality. In need of further work pass to a step 5.
