WHY DO STUDENTS REQUIRE ASSISTANCE IN
DATABASE ASSIGNMENTS?
Hierarchical data model - The data are
displayed in this form of the data model as a tree
with several branches on each trunk
Relational database - Information can be
organized in tables using a relational database.
It can connect data by merging tables, which
facilitates understanding and provides insights
into the relationship between different data
points
Flat model - All the data is retained on the same
level in a flat data model. All data element in the
flat database model is depicted by a single, two-
dimensional matrix, with rows having
interpersonal values and columns having values
of a comparable nature.
Network database model - In a network
database model, many files or records can be
connected to numerous owner files and vice
versa.
