Question

Compare the memory and processing requirements for a DDMS to an object-oriented database system.

Include the following in your comparison:

• Types of memory
• Memory requirements
• Types of processing
• Required transfer rates
• Record types
• Storage architectures
• Considerations related to the overall system performance and scalability

Answer 1

DDMS:

1.)They move data from disk to memory

2.)Data elements need to access individually.

3.)No relationship between data.

4.)Normalization is not present.

5.)It does not support distributed database.

6.)It stores data in either a navigational or hierarchical form.

7.)The data is subject to low security levels with regards to data manipulation.

8.)Data redundancy is common in this model.

9.)It stores data as file.

1.)Object based Storage memory

2.)An object identifier (OID) is an unambiguous, long-term name for any type of object or entity.

3.)Data Encapsulation.

4.)Class describes a group of objects that have common relationships, behaviors, and also have similar properties.

5.)Stores data as well as methods to use it.

6.)Handles larger and complex data than RDBMS.
