Records follow a uniform format, and there are no structures for indexing or recognizing relationships between records. The file is simple. A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file. Relationships can be ...
Its database utilizes a hash-file system, enabling efficient data storage and retrieval by organizing data into dynamic associative arrays managed by associative files. Data within the Pick system is organized into a hierarchical structure of accounts, dictionaries, files, and sub-files based on a hash-table model with linear probing.
