Java can handle simple parsing of semi-structured JSON data, but has difficulty in handling the in-depth processing. esProc, which supports set operations, order-related operations and dynamic script execution, can help reduce the difficulty. A Java application will execute an esProc script in the same way as it execut...

Sometimes you need to query a big text file, instead of the database. In those cases, you need to retrieve the file in a stream style to perform the query algorithm, in which parallel processing is needed to improve the computing performance. As Java lacks the class library for doing these, you have to use hardcoding t...

Encapsulated lots of functions for handling structured file computing, esProc can import text files with complex formats, implement cursor-style processing with big files and simplify multithreaded parallel processing. A Java application can pass in parameters, execute an esProc script the same way as it executes a dat...

Java provides functions for handling the basic file processing, which refers to the retrieval of small text files, in a simple, unstructured way. But in handling files requiring structured format, holding data of various formats and having particular requirements, or big files that cannot be entirely loaded into memory...

In some cases, data must be stored in the file system, rather than in a database. That requires handling file-based data computing manually. Since Java lacks the related class library, you have to hardcode the structured file computing, which produces complicated and unreadable code.
Yet, you can make up for this defic...
