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.
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.
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.
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.
A piece or item of information in a database is typically referred to as a "data point" or a "database record." It represents a specific value or set of values within a database structure that can be accessed, edited, or manipulated according to the needs of the user or system.
They would call it a record, a row or a tuple.
A mixed database is a system that contains different records that are set up in different files. This means that the database system will run several workloads simultaneously.
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.
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.
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
You can set up any database for real estate. If you have large data, better go for no-sql 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.
Depends on the database programming language
DBMS: Set of software applications combined w/ a database
Access is a database. Records are what each set of data is, so they are a key aspect of Access and any database. So that is why the icon is like it is.Access is a database.

a file when referring to electronic systems can be a programme or sequence event recoding structure a database file is a set of created datasets used for storing information in an information management system . database files can then be used to retrieve the input information or used to inform a series of preset and manually created reports
