XML is platform independent, which means that every program designed to use XML can read and manage XML data, regardless of hardware or operating system. For example, with the right XML tags, you will be able to use a program to open and operate data from a central computer. Also, regardless of whether the XML data is created by someone else, you can manage it using MS Office programs. As it is fully portable, XML has become one of the most popular technologies for exchanging data between databases and user desktops.
Quick review of the schemes
Don’t be intimidated by the word “diagram”. A schema is simply an XML file that contains the rules referring to the content of an XML data file. Schema files use the extension .xsd, while XML data files use the extension .xml.
The diagrams will allow programs to validate the data. This provides a framework for structuring data, ensuring that data has meaning for the creator and any other user. For example, if a user enters incorrect data, such as text in a data field, the program will warn the user to enter the correct data. As long as the data in an XML file is entered taking into account the rules of a given schema, any program that accepts XML can be used as a schema to read, interpret and modify the data.
Schemes that allow the applications to split XML data
The schemes can become complex. You will have to know how they are looking, even if you are not going to use them. However, this is only for making a difference between them. You will never need them as a simple user, and your IT department is responsible for creating the schemes, so you must contact them whenever you have problems.
Don’t worry if you can’t understand it. Just keep in mind the following aspects:
The elements of the line are called declarations. If you need additional information about an animal, such as color and brand, there is a chance that IT will add it to the diagram. The XML system can be changed as the system evolves.
Statements provide enormous control over the structure of the data. For example, the declaration <xsd: sequence> tells you that tags, such as <NAME> and <BREED> can be displayed in the correct order. Statements can also control the type of data that users can enter. For example, the scheme requires a positive integer for the age of the dog and a logical yes / no value for the Altered and Declawed tags.
The data conforms to the rules proposed by the diagram, and it is considered that the characters entered are valid. The biggest advantage of schemas is that they make sure that all the data is valid and that they also facilitate the process of detecting incorrect data, warning users of this aspect.
