A database is a collection of tables that is used for some purpose (typically an application of some sort). A database model is a description of that database, and describes how the tables relate to each other. Typically, a model is designed first, then the actual database is implemented using the model as a blueprint.

Contrast of database and database system?
A database is simply a collection of pieces of information (data). A text file storing names and phone numbers is a database. A database management system (DBMS) is some software that manages the data within the database such as MySQL. Both the software and the database are considered together when thinking of a DBMS.
What is the difference between a stored database procedure and a batch of SQL statements submitted by a client application?
Stored procedures prevent unauthorized access to data
What is the difference between a programming language and a database?
Programming language is to develop an application where a database is a place at which we can store the data about any objects and a software which maintains this database is called DBMS.
Why relational database approach is better than earlier method?
Relational model helps in logical relation between two dimensional tables . It maintains data integrity and eliminates data redundancy. Earlier methods involved redundant set of data for maintaining relations between set of data.
What is difference between object and entity?
A database object is represented as one of the following: database, schema, table, column, primary key, and foreign key A database Entity is: An entity is a thing or object of importance about which data must be captured. All things aren't entities - only those about which information should be captured. Information about an entity is captured in the form of attributes and/or relationships. If something is a candidate for being an entity and it has no attributes or relationships, it isn't an entity. Database entities appear in a data model as a box with a title. The title is the name of the entity.
What is the difference between data model and schema in database?
As I understand it, a database schema is a physical entity, it describes the structure of exactly how the data is stored and is itself stored by DBMS for reference. Data model, on the other hand, is an abstract representation of database.
What are the advantages and disadvantages of network data model?
Network data model is just like a normal database model. In network model the data is seen as related to each other by links. Or we can say the relation between the data is represented by links.
What is the difference between database and database administrator?
Database is the data stored in the server and Database administrator is the person who designs the database.
Difference between database and relational database explain with example?
Database = Generic name for a system to store data Relational Database = A specific type of database that utilizes relationships between data to not only store the data but further its efficiency in its manipulation.
What is the difference between a model-driven and data-driven DSS?
What is the difference between a model-driven and data-driven DSS?
Difference between logical database and physical database?
The logical database is how the data is percieved in the tables, the way the data is actually stored on the storage medium is the physical view of the database.
Is there a difference between a database and a data capture form?
Yes, a very fundamental one. The form is the interface that allows you (or a user) to add data to the database. The database is the thing that stores the information and retrieves it when queried by the database operator.
What is difference between data dictionary and database schema?
A data dictionary is a collection of metadata about the data elements in a database, where as, a database schema is a design blueprint for how data is structured and organized within a database. The data dictionary describes the data, while the schema defines how the data is stored.
How does data modelling lead to the design of a database?
The data model identifies the objects/entities involved in the application and the relationships between them. From that, the ER diagram is solidified and this forms the basis of the database design.
Difference between Object-based Data Model and Record-based Data Model?
RECORD type works only in PL/SQL. But OBJECT type gets stored in database and can be used in both SQL and PL/SQL (without redefining it in PL/SQL).
What are the Classification of data model?
what are database models
What is the difference between dataset and database?
A data set (or dataset) is a collection of data, usually presented in tabular form whereas A database is an organized collection of data for one or more purposes, usually in digital form.
