Shared Database
• Integrate applications by having them
store their data in a single Shared
Database, and define the schema of the
database to handle all the needs of the
different applications
Shared
data
Characteristics
• SQL-based relational databases
• All application development platforms can
work with SQL
• Transaction management systems
• Applications are always consistent all of
the time
Side Effects
• Applications coupled to the database
• Semantic dissonance
• Performance bottleneck
• Can cause deadlocks
• The unified schema can result in a schema that
programmers find difficult to work with
• Most packaged applications won't work with a
schema other than their own
• Software vendors usually reserve the right to
change the schema with every new release of
the software
