Is a logical description of some portion of database that is required by user to perform some task.
implementation level
three levels of data abstraction are: 1. Physical level : how the data is stored physically and where it is stored in database. 2. Logical level : what information or data is stored in the database (like what is the datatype or what is format of data. 3.View level : end users work on view level. if any amendment is made it can be saved by other name. for the database to be usable it must retrieve data efficently.this efficency led designer to use complex data structure in the database
Data binding is a very useful feature used in software development technologies. It acts as a bridge between the overview and business logic for the application. AngularJS follow Two-Way Data Binding. Data can be binded in two ways: 1.One -Way data binding 2.Two-Way data binding Silicon Valley provides services like: Angular JS application Development Node JS Development React Native Development
A remote data object is one that would be located on a different "node". For instance, a node the hardware where the operating system resides, which houses a database. Nodes have IP addresses and names. Say that the main database resided on node "Payroll" (10.128.132.10). Via a database link, an object from another node "Accounting" (10.128.142.11) is referenced. An example of this could be a view which pulls data from a table in the Payroll database and joins it to a table in the Accounting database and the view shows data from both nodes.
Your order is incorrect. The database exists and is populated with the data wanted on the page, Java extracts the data needed from the database and renders the page in the necessary HTML for the browser to view. You could see a JSP reference in the address for Jave Server Page or not.
A graph is a visual view of data; a table is the numerical view of data.
form view
In Microsoft Access, a valid report view includes options like "Print Preview" and "Layout View." However, "Data Sheet View" is not a valid report view; it is used for tables and queries. Reports are specifically designed for presenting formatted data, while Data Sheet View is oriented towards data entry and manipulation.
A data sheet view shows the data in the database. It allows you to enter and edit the data, but you cannot change the format of the database. Design view allows you to create or change the table, form or any other database object.
a data model
The logical view presents data as they would be perceived by end users or business specialists, whereas the physical view shows how data are actually organized and structured on physical storage media.
Design View
One of the views a form has is Design View. It is used when designing the form, so it does not show the actual data. There is also a view called Form View, which shows the data.

Form View.
View is a virtual table that do not have any data of its own but have data that is derived from another table called base table. Create view is the command used to create a view (virtual table).
