What Is a Relational Data Base?

Although relational databases sound intimidating, at its most basic, a database is simply a place to store information. Databases play an important role in data analytics, software engineering, data engineering, and other areas. This can look different in practice, but relational databases are a special type of database used to store and retrieve data from apps.

Because they are flexible enough to cover many industry uses, relational databases are very popular. You might be familiar with industry favorites such as SQL Server, MySQL and PostgreSQL even if you haven’t had the opportunity to use one.

What is a relational data base? You are probably familiar with Excel spreadsheets. They work in similar ways. A database can be thought of as having the same column and row structure. However, they are based on the idea of a table but have certain features that allow for data retrieval and analysis.

Multiple tables are common in databases. They can be linked together if there are overlapping columns or, in industry jargon: a primary key. Companies can use this interlinking architecture to help them make sense of the different types of data generated by their business lines.

The Relational Database Model

Let’s first look at the reasons that the relational database was created. E. F. Codd, an IBM employee, created the relational database in the 1970s. He wrote a paper outlining the rules for data storage. Each row has a unique primary key. Tables are related to each other if they have columns that correspond to the unique key. The foreign key occurs when the primary key is used in a different table.

Relational databases define the data types in each column, as well as primary keys and column names. These attributes are called the relational schema and they structure how new entries are added into a database.

This may seem too abstract. If you’re interested in analytics, it might be hard to conceptually understand why. Let’s look at an example of how businesses use them.

Let’s say you have a shoe company that sells online. They will store customer data across multiple databases depending on which data is stored when a customer orders shoes online. The columns in the Customer table could include Customer ID and Mailing Address as well as Purchase ID and Purchased Item ID. Columns in the Marketing table might include Customer ID, Transaction Amount, Purchase ID, Promotional Campaign, Purchase ID, and Purchase ID.

This simplified database shows Customer ID as the primary and foreign keys. We can now see the effect of marketing on sales generation.

Austin is the capital of Texas. It also serves as the seat of Travis County and the largest city in Travis County. Parts of Austin extend into Hays and Williamson. It was founded on December 27, 1839 and is currently the 11th most-populous US city. It is also the fourth-most populous Texas city. Since 2010, it has been one the largest and fastest-growing large cities in America. Downtown Austin and Downtown San Antonio lie approximately 80 miles (129km) apart. Both are located along the Interstate 35 corridor. Some believe the two regions could one day become a “metropolis” like Dallas or Fort Worth. Austin, the capital of the state of Texas in the contiguous United States, is a “Beta-” global city according to the Globalization and World Cities Research Network.

History

Since at least 9200 BC, Austin, Travis County, and Williamson County have been home to human habitation. According to evidence found in the region and at the well-studied Gault site, which is midway between Fort Hood and Georgetown, the area’s earliest inhabitants lived during the Pleistocene (Ice Age), they are connected to Clovis culture around 9200 BC (over 11200 years ago).

The area was inhabited by the Tonkawa tribe when European settlers arrived. It was also home to the Lipan Apaches and Comanches, who were known to have traveled through the region. Spanish colonists, including the Espinosa-Olivares-Aguirre expedition, traveled through the area, though few permanent settlements were created for some time. Three Catholic missions from East Texas were merged in 1730 and reestablished as one mission in Zilker Park in Austin. After seven months of being in the area, the mission was transferred to San Antonio de Bexar where it was split into three missions.

Climate

Austin is situated in the middle of a narrow transitional zone that separates the dry deserts and lush green regions of the American Southwest from the more humid, lusher areas of the American Southeast. Both its climate, topography and vegetation have similarities. According to the Koppen climate classification, Austin is classified as a humid subtropical climate. This climate has long, hot summers and short, mild winters. There are also warm, to hot springs and fall seasons. Average annual rainfall in Austin is 34.32 inches (872mm), distributed evenly through the year. Spring and fall are the most wet seasons.
