When comparing two files in Cobol code, there are several factors to consider before choosing a method. Firstly, the type of data contained in the files should be taken into account. If both files contain structured data, SQL queries may be the most efficient and effective method for comparison. However, if one or both files contain unstructured data, a file comparison tool or scripting language may be more suitable.
Another consideration is the complexity of the comparison required. For simple comparisons, a file comparison tool may be sufficient. However, if you need to perform complex analysis or comparisons, using a scripting language can provide greater flexibility and control over the comparison process.
It’s also important to consider the resources available to you. SQL queries may require additional software and hardware, while file comparison tools and scripting languages are often built into standard operating systems and can be run on any computer with an internet connection.
In conclusion, when comparing two files in Cobol code, it’s important to carefully consider the type of data contained in the files, the complexity of the comparison required, and the resources available to you. With these factors in mind, you can choose the most appropriate method for your needs and effectively compare your data.
