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
Logical Structure of database is know as database schema. All database entities are defined and relation between then is represented in structured way. It includes all constraints to be apply on each identity.

A database management system (DBMS or simply database) forms the back-end of a data information retrieval system. Data retrieval is just one component of a DBMS; data input, storage and maintenance being the other major components.
A structure is a collection of primitives or other structures. A pointer is a memory address. Comparison of the two is like comparing bowling balls to cinder blocks. You can say that a structure defines the layout of the data, while a pointer points to data that is a particular structure.
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.
Database is the data stored in the server and Database administrator is the person who designs the database.
You create your own data structure in database.
A logical database is the structure of data. It is the different pieces of information and the relationships between them.
A logical database refers to the way data is organized, modeled, and accessed by users, focusing on the structure and relationships of data. In contrast, a physical database relates to how data is actually stored on disks, including indexes, partitions, and access paths designed for efficient data retrieval and storage.
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.
If you know the database structure, the data is often easily viewable.
Data refers to raw facts and figures, while a data element is a unique unit of data that represents a specific attribute or characteristic. Data elements are used as building blocks to organize and structure data within a database or system.
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.
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.
A relational database is a type of database, so in one sense there is no difference. There are various kinds of database. A relational database is one type. Others include network and hierarchical.
