The third level of the architecture is the internal level. The internal view is a low level representation of the entire database; it consists of many occurrences of each of many types of internal record. "Internal record" is the ANSI/SPARC term for the construct that we have been calling a stored record.

What is high-level description of a conceptual data?
A conceptual data model is a high-level overview of the structure and relationships within a database. It focuses on the entities, attributes, and relationships between entities without going into the specifics of how the data will be implemented in a physical database. It serves as a blueprint for designing a database system.

A relational database is a type of database that stores and organizes data in tables with a predefined structure.

What is database query?
A database "query" is basically a "question" that you ask the database. The results of the query is the information that is returned by the database management system. Queries are usually constructed using SQL (structured query language) which resembles a high-level programming language.
How do you explain in detail the role of dba also explain oracle tools available?
The database administrator performs a critical role within an organization and is an important and key role in Database Management Systems. The major responsibility of a database administrator is to handle the process of developing the database and maintaining the database of an organization. The database administrator is responsible for defining the internal layout of the database and ensuring the internal layout optimizes system performance.The database administrator has full access over all type of important data of an organization. The database administrator decides what data will be stored in the database and how to organize data in database so that it can be access easily on requirement or need of an organization. To design the database of an organization, the database administrator must have a meeting with users and determine their requirements.

How do you xxplain the ANSI SPARK data model?
The ANSI-SPARC Architecture, where ANSI-SPARC stands for American National Standards Institute, Standards Planning And Requirements Committee, is an abstract design standard for a Database Management System (DBMS), first proposed in 1975 .A standard three level approach to database design has been agreed.- External level- Conceptual level- Internal level (includes physical data storage)The 3 Level Architecture has the aim of enabling users to access the same data but with a personalised view of it. The distancing of the internal level from the external level means that users do not need to know how the data is physically stored in the database. This level separation also allows the Database Administrator (DBA) to change the database storage structures without affecting the users' views.External Level (User Views)A user's view of the database describes a part of the database that is relevant to a particular user. It excludes irrelevant data as well as data which the user is not authorised to access.Conceptual LevelThe conceptual level is a way of describing what data is stored within the whole database and how the data is inter-related. The conceptual level does not specify how the data is physically stored.Internal LevelThe internal level involves how the database is physically represented on the computer system. It describes how the data is actually stored in the database and on the computer hardware.Most modern commercial DBMS are based on this system. The ANSI-SPARC model however never became a formal standard.
