Storage structure

This is the fundamental difference between the two. In a relational database, each individual piece of information is stored as a separate file, independent of the others, and there is no support for persistent storage of objects with a complex structure.
The focus is on more direct data .
Object-oriented databases use identifiers to label each object, along with indexing techniques to locate pages on disk. As a result, the system can support more complexly structured objects.
Information retrieval method
For your data to be truly useful, you also need turkey phone number list an effective recovery method. Without this, it will not be practical to apply it to day-to-day decision making.
An object-oriented database, as we have already mentioned, uses object identifiers, which are like labels.
When you perform a search for one of these tags, the system brings up the set of files and information it contains. And, within that object, there may be other types of hierarchies and internal relationships.
The relational model, in turn, makes use of two relational keys. The primary, as already mentioned, is the base, usually represented in the first column of the table, which identifies each row. Then a foreign key is used, which is related to the primary. Together they serve as a coordinate to locate the information sought .
There may also be secondary or tertiary keys, which act as search filters. In this way, it is possible to use other keys and separate those that have specific information in a given area or those that have an empty area.
