A Note on Program Examples
Many examples in this documentation use data from the Aviation.Event SQL table. If you wish to use this sample data, it is available at https://github.com/intersystems/Samples-AviationOpens in a new tab. (You do not need to know anything about GitHub or have a GitHub account.) Locate the contents of the README.md file, which appears below the filenames and directories included in the GitHub repository. Scroll to the “Setup instructions” section at the bottom of the README.md file and complete the steps.
Many of the program examples in this manual begin by deleting a domain (or its data) and then loading all data from the original text files into an empty domain. For the purpose of these examples, this guarantees that the NLP indexed source data is an exact match with the contents of the file(s) or SQL table(s) from which it was loaded.
This delete/reload methodology is not recommended for real-world applications processing large numbers of text sources. Instead, you should perform the time-consuming load of all sources for a domain once. You can then add or delete individual sources to keep the indexed source data current with the contents of the original text files or SQL tables.
