What Is a Database?
In a database, information is organized into tables. Rows and columns make up the structure of a table. Attributes are shown in the columns. Attributes such as ID, name, city, location, mark1, mark2, etc. can be found in the student table in the school database. In the database, each row represents a distinct individual. In this case, each row represents a single student's whole record collection. Maintaining a database is usually a good idea because it helps keep track of information. There may be different tables for teachers, students, courses, and so on in a school database.
The software that assists in the management of databases is known as a database management system (DBMS). Database management systems (DBMSs) such as MySQL, MSSQL, Oracle, and PostgreSQL are among the most used. Structured Query Language (SQL) can be used by the user to perform database operations. OLTP, or Online Transactional Processing, refers to the method used to run database queries online. Because of this, OLTP is used by a database. Overall, a database helps to organize a collection of information.
What is a Data Warehouse?
The use of Business Intelligence (BI) can help businesses grow. It transforms raw data into information that may be used for business analysis. As a result, end users benefit from better business insights. Support for the business intelligence process is provided by using a data warehouse. Oracle, MySQL, and other databases can be used by a corporation. In some databases, it is not possible to see the data directly. This problem can be solved with a data warehouse. Integration and processing are carried out on the data it collects and processes. A visual representation of this data is possible. Subject-oriented, integrated, time-variant and nonvolatile are the characteristics of data warehouses.
Difference Between Database and Data Warehouse
Detailed data can be found in the database, whereas summary data can be found in the data warehouse.
While OLTP is used in databases, OLAP is used in data warehouses to analyze data (OLAP).
Data warehouses and databases are two separate tools that can be used to conduct basic business functions.
Speed and Accuracy
Using a data warehouse instead of a database is faster and more accurate.
A database's primary focus is on serving a specific business need. Subject-oriented data warehousing. Instead of storing information based on a certain application, it organizes it according to the business topic.
Tables and Joins
Normalized tables and joins in a database make them more difficult to understand. This reduces the amount of redundant data. Contrarily, denormalized data warehousing tables and joins are much easier to work with. Analytical inquiries can take a long time to answer, so here is a way to speed up the process.
A database can be designed with the help of entity relationship modeling. The development of a data warehouse is made easier by the use of data modeling techniques.
A DBMS is a Database management System, it consists of the tools needed to access or build a database. A Data Warehouse is merely a collection of data from one or more sources collected together to enhance the the activities of data mining, which is performed with a DBMS or a RDBMS*.
*Relational Database Management System
what is difference between traditional DBMS and data warehousing?
Traditional FPS and DBMS both are different from each other. In DBMS there is security of data as well as integrated data while this is not in FPS.
A centralized DBMS, or database management system, has data maintained and stored in one location. A distributed DBMS has data stored in storage devices that are in other locations.
DBMS overcomes all the disadvantage of traditional FPS. The main difference between FPS and DBMS is that FPS do not support data sharing, data security and non redundancy.
File system is the traditional method where data is stored and retrieved from files. But modern DBMS stores data in the database tables and retrieves them.
Relationship is purely a construct of the er data model.Relation is a structure of the relational data model.
A DBMS stores data in a table where the entries are filed under a specific category and are properly indexed. This allowed programmers to have a lot more structure when saving or retrieving data. A relational database contains data in more than one table. Each table contains a database that is then linked to other tables with respect to their relationships.

A data warehouse has multiple functional areas whereby a centralized organizational unit is responsible for implementing it. On the contrary, data marts focus on particular functional areas hence are simple forms of a data warehouse.
Redundancy is controlled when the dbms ensures that multiple copies of the same data are consistent. If the dbms has no control over this, uncontrolled redundancy.
Data warehouse is the database on which we apply data mining.
A database is used to store data while a data warehouse is mostly used to facilitate reporting and analysis.
SCHEMA is the physical arrangement of the data as it appears in the DBMS. SUB-SCHEMA is the logical view of the data as it appears to the application program.
