Hello!

Im pretty new in database world, so Im interested in the way the records are writenn in database, for example, in dBase. Is this happens cronologicaly, one by one, relaed to the time each record is created?

The general answer is: Each database engine is free to choose how it will store data, and how it will access data. Some database engines always do given operations is a single way, but most will choose between multiple options to get the best overall system performance.

Specific answers require VERY specific analysis.

Thank you for your answer, but I am confused.
Is it some kind of default setting that each new record comes after last one in the database?

How can one be sure that record X is created after or before record Y?

And one more question, please:

What is ODBS, is it the way application communicate with database? Also, what is DBF flat file system? Can someone explain me this in few words?

Thank you in advance!

It depends on the database engine, but in most cases you can't do that.This one is easy, since if the row doesn't have any data to allow you to determine the order in which it was received, there isn't a reliable way to tell.I don't recognize ODBS as a database related acronym. An OODBMS is an Object Oriented Database Management System which can be either an OOP wrapper for standard database calls or a full-blown OOP database which is a whole different kind of thing.[quote=RisBoW]A "Flat File" database is a VSAM file oriented database, meaning that the records stored are in a single file and all records have uniform size. Most flat file databases support but do not require indicies.
