Hackathon event in Chennai - Save the Hacker

Start: May 09, 2015 12:00AM
End:  May 11, 2015 12:00AM

Venue: Freshdesk, 7th Floor, SP Infocity, Block-B, MGR Main Road, Perungudi, Chennai, Tamil Nadu 600096, India

Description: Not so long ago, when tech jobs weren’t a commodity, people got excited about writing code. They fired up terminals, cloned repositories and went out of their way to build ideas from scratch. Google, Apple and Facebook happened. Life was awesome.

But then, somewhere along the way, the world got lost in a sea of corporate bullshit, incompetent project managers and made-up job roles. Writing awesome code didn’t really matter anymore, work lives became a 9 to 5 thing and god-level geeks allowed themselves to pursue strategic mediocrity. Today, the hacker is a dying species, endangered by pointless hierarchies, outrageous dress codes, and teammates who are hell-bent on being lazy.

But wait, there’s still hope.

Last year, Freshdesk, a startup from Chennai set out on a mission to save smart programmers from dead-end jobs by inviting them to Save the Hacker – a two-day hackathon that went on to change their lives. This year, we’re back, and we can’t wait to rescue more developers and see them build great products. So come join us in our mission, show us what you’ve got, and while at it, win some amazing prizes.

Dimension Table vs Fact Table

     Dimension table and fact table are mainly used in data warehousing. The fact table mainly consists of business facts and foreign keys that refer to primary keys in the dimension tables. A dimension table consists mainly of descriptive attributes that are textual fields.
      Dimension tables provide descriptive or contextual information for the measurement of a fact table. On the other hand, fact tables provide the measurement of an enterprise. A dimension table contains a surrogate key, natural key, and a set of attributes. On the contrary, a fact table contains a foreign key, measurements, and degenerated dimensions.
     When comparing the size of the two tables, the fact table is bigger than the dimensional table. In a comparison table, more dimensions are presented than the fact tables. In a fact table, less numbers of facts are observed. In a dimension table, the values are text representations or numeric. In a fact table the values are in integer form or numeric.
     A fact table normally contains two columns – one that contains the facts and the other foreign keys to the dimension table. Dimension tables are also called reference tables.
     When dimension tables can be loaded directly, it is not possible with a fact table. In a fact table, the dimension table has to be loaded first. While loading the fact tables, one should have to look at the dimension table. This is because the fact table has measures, facts, and foreign keys that are the primary keys in the dimension table.

Dimension Table features :
1. It provides the context /descriptive information for a fact table measurements.
2. Provides entry points to data.
3. Structure of Dimension - Surrogate key , one or more other fields that compose the natural key (nk) and set of Attributes.
4. Size of Dimension Table is smaller than Fact Table.
5. In a schema more number of dimensions are presented than Fact Table.
6. Surrogate Key is used to prevent the primary key (pk) violation(store historical data).
7. Values of fields are in numeric and text representation.

Fact Table features :
1. It provides measurement of an enterprise. 
2. Measurement is the amount determined by observation. 
3. Structure of Fact Table - foreign key (fk), Degenerated Dimension and Measurements. 
4. Size of Fact Table is larger than Dimension Table. 
5. In a schema less number of Fact Tables observed compared to Dimension Tables. 
6. Compose of Degenerate Dimension fields act as Primary Key. 
7. Values of the fields always in numeric or integer form. 

Difference between dimension and fact tables: 

1.dimension data is de-normalized where as fact table contains normalized data 2.dimension table contains many columns where as fact table contains less columns only 2 in fact 
3. the data in the dimension tables are less compared to the data in the fact tables 
4. The data in the dimension table is static and descriptive in nature where as the fact table contains numeric and will change regularly 
5. dimension tables generally called as look up or reference table as well. facts tables are the key performance indicators of the business 

Summary:
     The fact table mainly consists of business facts and foreign keys that refer to primary keys in the dimension tables. A dimension table consists mainly of descriptive attributes that are textual fields.
     A dimension table contains a surrogate key, natural key, and a set of attributes. On the contrary, a fact table contains a foreign key, measurements, and degenerated dimensions.
     Dimension tables provide descriptive or contextual information for the measurement of a fact table. On the other hand, fact tables provide the measurements of an enterprise.
