A data structure is the internal representation of the data. It may be a list, a linked list, a stack, heap or just about anything else that can be immagined and represented internal to the machine. For example, the data structure may be a linked list of control blocks for a specific product that is progressing through an automated machining facility. The control block may include information regarding the product, the tolerances, date/time that the product entered the different machining centers and the inspectors who verified the product at different points along the way. The data structure (control block) may or may not be stored in a database during the manufacturing process. Some application engineers may determine that the data needs to remain in memory to address real-time issues and for speed concerns. On the other hand, the data may be handed off to a database application for archiving. A well defined database links the similar data elements together and provides lookup "keys" that allow subsequent users to view and manipulate the data.
difference between serch data structure and allocation data structure
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.
You create your own data structure in database.
Database is the data stored in the server and Database administrator is the person who designs the database.
A logical database is the structure of data. It is the different pieces of information and the relationships between them.
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 data type and a data structure?"please send very soon within 1 day its very urgent.
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.
a manual data is created by a person but a electronic database is created by computer ect
File is a collection of records whereas database is a collection of data in a file
A database is used to store data while a data warehouse is mostly used to facilitate reporting and analysis.
data base is collection of information and data model is a previews data
If you know the database structure, the data is often easily viewable.
A database is a collection of data that is intended as a permanent resource. A business might have a database containing information about customers and products. A telephone company might have a database of telephone numbers, names, and addresses. A database could be as simple as a cabinet full of paper files where the data is written, even a stack of paper on the corner of a desk, but usually the word database is used to refer to data stored using a computer with a database management system. A data structure is a way of organizing data. A database will almost always use at least one data structure, because having organization allows the database to be used more easily, but a database could be a pile of scraps of paper on the floor and so be said to be completely unstructured. The term data structure will often mean the organization and not the data, so that two databases that are organized in the same way could be said to share the same data structure even if they contain different data and are separated by thousands of miles. It is also possible to have a data structure without a database if the data structure is being used for a temporary purpose and will be discarded afterward. This is common practice for the inner working of computers. In a restaurant a waiter may write down orders on pieces of paper and pass those pieces of paper in a queue to the kitchen. This would not normally be called a database because it is data that is only used once and then abandoned, but it is certainly a data structure. When the waiter makes a list of credit card numbers from the customers, then he is creating a database.
data is like the files that are put on table .while data base system is a system which is base on data and query.
DATABASE is a repository of data...... it is a place which holds the entire data together......while DATA DICTIONARY defines the basis to distinguish the data....this can be in the form of tables, views
Integrity refers to the structure of the data and how it matches the schema of the database. Correctness could refer to either the integrity of the data or its accuracy (for example, a phone number being incorrect).
database system is organized collection of data.data base management is a software and ti controls the data in a data base.
"Metadata" defines the structure of the data stored.
In general, a database is a collection of related data. In more specific terms, a database is typically a collection of computer files, usually stored on disk, used to contain and manage this data. The logical structure of a database (as organized in tables, indexes, views, etc.) does not necessarily correspond directly to its physical structure (the data files, transaction log files, etc.). A database instance is the instantiation of memory structures and processes by a database management system manages the logical and physical structures and the data organized and stored therein. An application program must connect to and interact with the database instance in order to insert, retrieve, modify, and/or delete data stored in the database.
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.
data in database is more secure as compared to file system.
They are both the data storage systems. In the case of data bank is emphasised the long time storage.
The representation of a particular data structure in the memory of a computer is called a storage structure.
