Concept of Database

To store and manage data efficiently in the database let us understand some key terms:.
1) Database Schema:It is a design of the database.
Or we can say that it is a skeleton of the database that is used to represent the structure, types of data will be stored in the rows and columns, constraints, relationships between the tables..
2) Data Constraint.

Database Abstraction

A major purpose of a database is to provide the user with only as much information as is required of them.
This means that the system does not disclose all the details of the data, rather it hides some details of how the data is stored and maintained.
The complexity of databases is hidden from them which, if necessary, are ordered through multiple .

Purpose of Database

The intent of a database is that a collection of data should serve as many applications as possible.
Therefore, a database is often thought of as a repository of information needed to run certain functions in a corporation or organization.
It would permit only the retrieval of data but also the continuous modification of data needed for the control.

What are some examples of DBMS?

A DBMS also facilitates oversight and control of databases, enabling a variety of administrative operations such as:

performance monitoring
tuning
backup and recovery

Some examples of popular database software or DBMSs include:MySQL, Microsoft Access, Microsoft SQL Server, FileMaker Pro, Oracle Database, and dBASE.

What types of data are used in a database?

Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient.
The data can then be easily accessed, managed, modified, updated, controlled, and organized.

Electronic collection of classic Jewish texts

A Torah database is a collection of classic Jewish texts in electronic form, the kinds of texts which, especially in Israel, are often called The Traditional Jewish Bookshelf ; the texts are in their original languages.
These databases contain either keyed-in digital texts or a collection of page-images from printed editions.
Given the nature of traditional Jewish Torah study, which involves extensive citation and cross-referencing among hundreds of texts written over the course of thousands of years, many Torah databases also make extensive use of hypertext links.
