In addition, it allows a dynamic mode, because it has an object-oriented perspective that is linked to each other, which is in contrast to a strict perspective of the SQL relationship. If you want to separate relational database tables into multiple data islands, the actually used SQL code will be much more than SPARQL-not to mention that there will be a lot of annoying JOIN descriptors in SQL. The first two lines of SPARQL are PR

For example, if a company goes bankrupt, what's the downstream effect on other assets in a mutual fund? What is happens to the companies that depended on the now bankrupt company? How should the financial institution reorganize it portfolio based on these events? SM: The first challenge the financial institution fa

Create, read, update, and delete (Create/read/update/delete,crud) operations are the most basic database operations, but they are also the most important operations. CRUD operations are usually done using the Structured Query Language (structured query language,sql) in the relational database system. As the Web becomes more data-oriented, it needs to move from sql-based crud operations to a semantic

We believe that this evolution can be performed in the following ways: (1)Semantic interval movement: from implicit semantics to standard Semantics (2)ReduceHardwiredProvides network content semantics.

Ontology is a science that studies various entities in the world and how they are associated. It obtains the knowledge of a certain field, describes the concepts of this field, and the relationship between these concepts. For example, animals and plants are different bodies.
