In hierarchical database structure, data elements are linked together as an inverted tree structure. there's a root data element, below the root ,there are subordinate elements, each of which has its own subordinate elements and so on. It can have multiple levels. Data elements have parent-child relationship. A parent data element can have more than one subordinate elements, but a child can be connected with only one parent. Its limitation is it cannot provide flexibility in data access. because every data element can be accessed through a definite path from the root data element. All the relationships between data elements should map properly when tree structure is first designed.this database model is used in several database applications because data elements of several applications can be organized as a hierarchical tree structure.

In what order is data organised in a DBMS?
Data in a DBMS (Database Management System) is typically organized in a hierarchical manner. The highest level is the database, which is divided into tables. Within each table, data is stored in rows, with each row representing a record. And within each row, data is further organized into columns, with each column representing a specific attribute or field of the record. This hierarchical structure allows for efficient storage, retrieval, and manipulation of data.
What is the difference between DBMS and msaccess?
