What is the difference between DBMS and Data warehouse?

Answer 1

A database is used to record, retrieve, update business transactions which are occured daily in business life. A data warehouse is used to record historical data, purely for analysis purpose for top management.

Answer 2

Data Warehouse is the place where all data has been stored. It provides easy access to the information which has to be relevant and time sensitive. Members of the company can access it any time and doesn't matter if the information needed is from the past or present.

MIS is used to analyze the information and decision making. It is the whole process of collecting and processing the information. At the end it can be shown in a form of graph or report to help management to forecast the best option for the company.

Answer 3

data mining is intended for users who are statistically inclined. These analysts look for patterns hidden in data, which they are able to extract using statistical models. Data miners engage in question formulation based primarily on the "law of large numbers" to identify potentially useful relationships between data elements, which can be profitable to companies. Data warehouse users,tend to be data experts who analyze by business dimensions directly. Data warehousing analysts are concerned with what kinds of purchases their customers make, and if the analyst can help the customer by improving the customer experience.

Answer 4

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*.

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

Data Type

Detailed data can be found in the database, whereas summary data can be found in the data warehouse.

Processing Method

While OLTP is used in databases, OLAP is used in data warehouses to analyze data (OLAP).

Usage

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.

Orientation

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.

Design Method

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.

Answer 6

A database is used to store data while a data warehouse is mostly used to facilitate reporting and analysis.
