Difference Between Fact Table and Dimension Table

Main difference

A fact table is known as the document that contains all the measures, dimensions, costs and events related to the process of a business or undertaking carried out within a particular range. An all-dimensional table is known as the document that contains all the measures related to the design and has descriptions of the factors, such as other attributes, lengths, time, and textual fields, such as discrete numbers.

Definition The document that contains all the measures, dimensions, costs and events related to the process of a business or undertaking carried out within a fixed range. The document that contains all the measures related to the design and has descriptions of all the factors such as attributes, lengths, time, and other textual fields such as discrete numbers.
Format It contains the data corresponding to a certain business process. Contains details about each instance of an object.
Content It is made up of commercial novelties and remote keys that allude to essential keys in the measurement tables It is primarily composed of graphic features that are printed fields.

What is the fact table?

A fact table is known as the document that contains all the measures, dimensions, costs and events related to the process of a business or undertaking carried out within a certain range. It helps to keep track of all the things that help to complete the task. In information storage, a fact table comprises the estimates, measurements, or facts of a business proceeding. It is situated at the focal point of a star map or snowflake outline surrounded by analysis charts. When different fact tables are used, they are organized as a celestial body construction of reality. A fact table typically has two types of segments: those that contain certainties and those that are a foreign key to the measurement tables. The essential key of a fact table is usually a composite kernel that is made up of most of its remote keys. Fact tables contain the essence of the clearinghouse and store distinctive types of measures such as aggregate substance, non-aggregate substance, and semi-aggregate element rules. A reality table contains the information that needs to be broken down, and a measure table stores information about the paths in which the information in the fact table can be investigated. In this way, the fact table is made up of two types of sections. The foreign key segment allows joining with metric tables, and the metric sections contain the information being dissected. There must be exceptional care in taking care of the proportions and the rate.

What is the dimension table?

A dimension table is known as the document that contains all the measurements related to the design and has descriptions of all the factors like attributes, lengths, time, and other textual fields like discrete numbers. It helps to ensure that all the things are completed as per the requirement. In information storage, a measurement is a collection of baseline data about a quantifiable occasion. These events are known as truths and are stored in a reality table. Measurements classify and describe the facts and measurements of the clearinghouse in ways that reinforce meaningful answers to business questions. They shape the very center of the dimensional display. The dimension tables contain information about each protest case. For example, the object dimension table would contain a record of everything sold in the store. You can enter data such as item cost, vendor, shading, sizes, and comparative information. Truth tables and measure tables identify each other. On the other hand, going back to our retail screen, the reality table for a customer exchange would likely contain a foreign key reference to the object measurement table, where the section is compared to an essential key in that table for a record that portrays the acquired object. For example, in the local situation, we talk about purchases, returns and calls being current. On the other hand, customers, workers, things, and stores are measures and must be included in dimension tables. Going back to our retail screen, the reality table for a customer’s exchange will likely contain a foreign key reference to the object measurement table, where the section is compared to an essential key in that table for a record that portrays the object. acquired. For example, in the local situation, we talk about purchases, returns and calls being topical. On the other hand, customers, workers, things, and stores are measures and must be included in dimension tables. Going back to our retail screen, the reality table for a customer’s exchange will likely contain a foreign key reference to the object measurement table, where the section is compared to an essential key in that table for a record that portrays the object. acquired. For example, in the local situation, we talk about purchases, returns and calls being topical. On the other hand, customers, workers, things, and stores are measures and must be included in dimension tables.

Key differences

  1. A fact table is known as the document that contains all the measures, dimensions, costs and events related to the process of a business or undertaking carried out within a certain range.
  2. A dimension table is known as the document that contains all the measurements related to the design and has descriptions of all the factors such as attributes, lengths, time, and other textual fields such as discrete numbers.
  3. Fact tables contain data that is relevant to a particular business process. On the other hand, dimension tables contain details about each instance of an object.
  4. The fact table is mainly made up of business updates and remote keys that allude to essential keys in the measurement tables. On the other hand, a dimension table is essentially made up of graphical features that are printed fields.
  5. A dimension table contains a surrogate key, a feature key, and a property layout. on the other hand, a fact table contains a remote key, estimates, and rejected measurements.
  6. The size of a fact table becomes much larger than the size of a dimension table, since the latter becomes part of the former and includes the details needed to complete the full cycle.
