Смысл: The main idea is that globals are low-level, highly efficient B-tree structures that can serve as a flexible 'constructor' for building various types of databases (Key-Value, Document, Relational) with superior performance in handling sparse, hierarchical, and massive datasets.
Globals in M/MUMPS act as a high-performance B-tree constructor capable of efficiently implementing everything from simple key-value stores to complex, schema-less hierarchical databases.
Смысл: The main idea is to introduce 'globals' as a highly efficient, tree-based persistent storage mechanism that outperforms traditional relational databases in specific high-load scenarios due to its inherent indexing and sorting capabilities.
Globals are persistent, automatically indexed hierarchical arrays that offer superior performance for data insertion and sub-tree deletion compared to relational databases.
Смысл: The main idea is that B-trees are essential for handling large-scale data storage because they minimize expensive disk I/O operations by utilizing a high branching factor to keep the tree height low.
B-trees are balanced search trees optimized for disk storage that reduce the number of I/O operations by allowing nodes to have more than two children.
Смысл: The main idea is that B-trees are superior to binary search trees for database indexing because they are optimized for physical hardware, reducing disk I/O by utilizing sequential access and maintaining a low tree height through multi-value nodes and self-balancing.
B-trees achieve high performance in databases by grouping multiple values into pages to minimize slow random disk access and using self-balancing to keep search depths shallow.
