Filename data is the name assigned to a file or document to identify it uniquely. It usually consists of a name and an extension, separated by a dot. For example, in the file name "document.docx", "document" is the name of the file and "docx" is the file extension that identifies it as a Microsoft Word document. The file name and extension are used by the computer's operating system and applications to locate, open, and process the file.
XML has not been widely adopted for web development and web services for several reasons:
Verbosity: XML documents can be verbose, making them larger and more difficult to transfer over networks than alternative data formats. This can slow down data transfer times, especially for web services that rely on fast response times.
Processing overhead: XML parsing and processing can be slow and resource-intensive, requiring significant processing power and memory. This can be problematic for web services that need to handle high volumes of data in real-time.
Hierarchical structure: The hierarchical structure of XML can make it difficult to efficiently search and analyze data, leading to slow query times.
JSON, in particular, has become a popular data format for web services due to its simplicity, ease of use, and support for real-time data transfer. JSON data is often smaller and faster to transfer than XML data, making it a good choice for web services that need to return data to client applications quickly. Additionally, JSON is supported by many programming languages, making it easier to integrate with existing web development technologies.
