A database provides structure, management and other capabilities like setting up relationships between entities. A set of independent files used to represent the same set of entities for example lack these capabilities, although you could provide these features yourself in your application. However, you will have to write a lot of code to do the same and it may not be that scalable either.

What is a record in the database?
In the structure of a database, the part consisting of several uniquely named components called data fields. Several data records make up a data file, and several data files make up a database.
Data base state vs database schema?
The database schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
How do you get the image file from the database with JSP?
You can retrieve an image file from a database in JSP by writing a servlet that fetches the image from the database and streams it to the JSP page. The servlet will set the content type to "image/jpeg" or the appropriate image format and write the image data to the response output stream. In the JSP page, you can then display the image by setting the source attribute of the img tag to the servlet URL.

What is the difference between database and files?
Files is any set of information or commands stored on your computer. A database is a collection of "files" that are interconnected or along the same subject...think customer's account information. While a database on a computer is a file, or set of files, a file does not have to be a database.
What are the advantages or disadvantages of a numerical vs. alphabetical paper filing system for 40000 plus files?
The only disadvantage is when the database creater is less than professional in how the database is set up. If you use a numeric as the unique identifier for the database then the database can quickly become both useful and huge.
How many max data files can there be in an Oracle Database?
There can as many as the Operating System will support. The limitation of "how many" is set by the OS and not the database. Two Oracle parameters to research that are related to your question however.... db_files, and maxdatafiles
What is the Difference between instance and physical database?
The terms instance and database are closely related, but don't refer to the same thing. The database is the set of files where application data (the reason for a database) and meta data is stored. An instance is the software (and memory) that Oracle uses to manipulate the data in the database. In order for the instance to be able to manipulate that data, the instance must open the database. A database can be opened (or mounted) by more than one instance, however, an instance can open at most one database.
How do I set up a database for real estate?

How will you set the length of a text field in database?

What is the difference between a database management system and a database?
DBMS: Set of software applications combined w/ a database
What is the difference between traditional file based approach and database approach?
There are significant differences in physical implementation of how data is stored and used. A database allows for data to be recorded in related structures with optimization aligned to the goals of the model for efficient use. The classes or record types in a database could be considered like lists in a file, though within the framework of the database management system (dbms) that relates, stores, indexes, retrieves, and updates the data in place. Ordinarily, file-based storage is for simpler, less structured lists that do not need to be related to data in other files as dynamically as a database. In practice, their use is significantly different, but conceptually there are many overlaps. One could denormalize the data in a database into a set of files suitable for some data processing needs, and databases are implemented in system files that are managed by the dbms, through which the developer and user operate.
What is jdbc?
JDBC stands for Java Database Connectivity . It was developed by Java soft and is a part of Java Enterprise API. JDBC is the first standardized API that allows the users to develop database front ends without continously rewriting their code. JDBC provides the ability to create robust, platform-independent application and wev-based applets, wihich can acces any database through a DBS-independent mechanism. The interaction between these application and applets with SQL data sources is done through a set of relational database objects and methods defined is the JDBC API.
