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 Level
The 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 Level
The 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.
What else can I help you with?
Compare the three level of ansi-sparc?
Conceptual database design is the process of constructing a model based on the enterprise. Logical database design is the process of constructing a specific data model. Physical database design is the process of producing of the database on the secondary storage.
What Is ANSI SQL?
ANSI SQL is the American National Standards Institute standardized Structured Query Language. ANSI SQL is the base for several different SQL languages such as T-SQL and PL/SQL. ANSI SQL is used to Create, Alter, and View data stored within a database. For more information about ANSI: http://www.ansi.org/ For more information about SQL: http://en.wikipedia.org/wiki/SQL

What is ANSI 837 encounter?
ANSI 837 Encounter is a standardized electronic format used in the healthcare industry for submitting claims related to services provided to patients, especially in outpatient settings. It is part of the ANSI X12 EDI (Electronic Data Interchange) standards and is commonly utilized by healthcare providers to transmit encounter data to insurers, Medicaid, or Medicare. This format ensures consistent data exchange, streamlining the billing process, and facilitating efficient claims processing and reimbursement.
How do you xxplain difference between grouped and ungrouped data?
Grouped Data:Where the data you have can fit into a group for example Large, Small, 2D Shapes, 3D ShapesUnGrouped Data:Where the data you have does not fit into a group (E.g. 1cm, 4, Brown, Yellow
Does a Software Company require permission from ANSI X12 organization to build a product that reads and writes ANSI X12 compliant data?
I'm not sure that they would need permission to create a product to read or write the data, I don't think so. However, they would need the standards data files to do validation, which I believe have to be purchased from them. Sorry I wasn't much help!1
Difference between void pointer and null pointer?
A Null pointer has the value 0. void pointer is a generic pointer introduced by ANSI. Before ANSI, char pointers are used as generic pointer. Generic pointer can hold the address of any data type. Pointers point to a memory address, and data can be stored at that address.
Explain data model?
Explain data model?
Define data models and list different types of data models?
A data model is a collection of concepts that can be used to describe the structure of a database and provides the necessary means to achieve this abstraction whereas structure of a database means the data types,relationships and constraints that should hold on the data. Data model are divided into three different groups they are 1)object based logical model 2)record based logical models 3)physical models Types: Entity-Relationship (E-R) Data Model Object-Oriented Data Model Physical Data Model functional data model
Can you explain how to use Spark to analyze big data sets efficiently?
Spark is a powerful tool for analyzing large data sets efficiently. To use Spark effectively, you need to write code in a programming language like Scala or Python. You can use Spark's APIs to perform various data processing tasks, such as filtering, aggregating, and joining data. Spark also allows you to distribute your data across multiple nodes in a cluster, enabling parallel processing and faster analysis. By leveraging Spark's in-memory processing capabilities and fault tolerance mechanisms, you can analyze big data sets quickly and effectively.
What is data model?
In computer science, data modeling is the process of creating a data model by applying a data model theory to create a data model instance. A data model theory is a formal data model description.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
