Data base state vs database schema?
The database state refers to the current data stored in the database, including all records and their values. On the other hand, the database schema refers to the structure of the database, including tables, columns, constraints, and relationships. The schema defines how the data is organized and stored in the database.
Which database is most suitable for small and large organization rational or object?
There is ONLY one type of database that is underlain by sound mathematical theory (Relational Calculus/Algebra see related link below) by means of which you can prove theoretically that the database works and that operations across it are true and valid. That database is the Relational Database. It would be incorrect for an organization to trust its data to ANY database that was not provably correct (if something was to go wrong the directors could be sued for choosing a database where they could not prove it was sound). Therefore the choice would have to be to place the company data into a Relational Database. An object oriented database could be used ONLY if it was implemented in/on a underlying Relational Database engine/platform (which is possible). Further, while object databases have acquired a niche in application areas such as engineering and spatial databases, telecommunications, high energy physics, molecular biology, in embedded use in devices and in real-time systems (where the requirement for data storage and retrieval is constrained to specific, narrow tasks and where speed is essential, I know of no implementation where an object database is used for corporate/business information.
What does time is relevant mean?
That time pertains to an individual/object or space/situation and there is no overall time that is the same for everything.
Definition of manual database?

It does not matter if you pay the fines on time or not, the information about your getting a driving infraction (ticket) is still entered into (and able to be viewed) by any State Agency (or individual), it is considered a part of the public records.
What are the Advantage and disadvantages of OODBMS?
OODBMS completely negates "impedance mismatch": a problem always faced by a custom software development company in a Relational Database System. In RDBMS, there was enough wastage of time when objects had to be mapped with tables and vice versa. This is completely avoided with OODBMS.In OODBMS, data is described easily through class hierarchy.IN RDBMS, users have to face problems when identifying the records. They had to ensure that no two records had the same primary key. OODBMS completely avoids this aspect because of its unique OIDs.Since interaction between objects and database is done transparently, there is no need for a query language to access data from an Object Oriented Database Management System. But one can still use queries in OODBMS.In OODBMS, a large class can hold several medium-sized classes, which can hold even more medium-sized classes. This means that OODBMs has the ability to handle complex data compared to RDBMS.
What is the definition of a form in access?
A form is an object that allows you to input, edit, or view data from/in your database. Forms usually displays one record at a time and can be customized based on user preference.
5 Explain why the allocation of records to blocks affects database-system performance significantly?
To access a record, the entire block that containg the target record must be loaded into the main memory and it is time consuming. It involes seek time, rotational delay and block transfer time.
