A schema for storing the meta data that describes relational databases. Advantageously, the schema can be used in both database vendor environments and toolkit vendor environments, thereby facilitating the sharing of relational database types. In addition, by describing the schema in a standard ...
It’s difficult for other types of databases to maintain this level of timely consistency with large amounts of data. Some recent databases, such as NoSQL, can supply only “eventual consistency.” Under this principle, when the database is scaled or when multiple users access the same data ...
