Layer4: Analytical Data Warehouses

Big Data Analytics

In order to make sense of huge data, existing analytics tools and approaches will be quite useful. There is, however, a catch. These tools' algorithms must be capable of dealing with massive amounts of possibly real-time and diverse data. Additionally, manufacturers of analytics tools must ensure that their algorithms work across distributed implementations. We foresee a new class of tools to help make sense of large data due to these complications.

In this layer of our reference architecture, we list three types of tools:

Reporting and dashboards

These tools display information from many sources in a "user-friendly" style. Despite being a stalwart in the traditional data world, this area is still evolving for big data, despite being a stalwart. Traditional technologies are being used, but they can now access the new types of databases collectively known as NoSQL databases.

Visualization

These technologies represent the next level in reporting's progression. The resulting result is usually highly interactive and lively. Animation is another major feature between reports and graphical output. Business users can use a range of visualisation approaches to track data changes, such as mind maps, heat maps, infographics, and connection diagrams. Reporting and visualisation are frequently done towards the end of commercial activity. This is the final stage, even though the data can be loaded into another tool for further processing or analysis.

Analytics and advanced analytics

These tools enter the data warehouse and process the information for human consumption. Trends or events that are transformative, distinctive, or revolutionary to current business practice should be explained using advanced analytics. This science is exemplified by predictive analytics and sentiment analytics.

Analysis Type

When it comes to analytics, there are a variety of options to consider.

Basic analytics

If you're not sure what you have but think it's valuable, you can apply basic analytics to investigate it. Basic analysis is frequently used when dealing with vast amounts of heterogeneous data.

• Slicing and dicing: Breaking down your data into smaller sets that are easier to investigate is referred to as slicing and dicing.
   
• Basic monitoring: Users also wish to keep a real-time eye on enormous amounts of data. For example, you might wish to monitor the water column properties in the preceding example every second for a long time from hundreds of sites and at different heights in the water column. This would result in a massive data set.

• Anomaly identification: The user may want to look for anomalies in your data, such as an occurrence where the actual observation differs from what you expected, because this could indicate that something is wrong with your organization, manufacturing process, or other factors.

Advanced analytics

Advanced analytics provides algorithms for the complex analysis of either structured or unstructured data. Statistical models, machine learning, neural networks, text analytics, and other advanced data-mining approaches are all included.
 

Here are a few examples of advanced analytics for big data:

• Predictive modeling: One of the most common big data advanced analytics use cases is predictive modelling. A predictive model is a statistical or data-mining solution that combines algorithms and strategies to forecast future outcomes from both structured and unstructured data (either together or separately).
   
• Text analytics: Because unstructured data makes up so much of big data, text analytics — the process of analysing unstructured text, extracting useful information, and translating it into structured data that can be used in a variety of ways — has emerged as a critical component of the big data ecosystem. Text analytics employs techniques from computational linguistics, statistics, and other computer science disciplines in their analysis and extraction procedures.
   
• Other statistical and data-mining algorithms: Advanced forecasting, optimization, cluster analysis for segmentation or even microsegmentation, and affinity analysis are all examples of this.

FAQs

What is an analytical datawarehouse?

A data warehouse is an analytics database that stores and processes your data for analytical purposes. Your data warehouse will be responsible for two major purposes in your analytics: storing and processing your analytical data.

What are data warehouses used for?

Data warehouses are relational environments for analysing data, mainly historical data. Data warehouses are used by businesses to uncover patterns and relationships in their data over time.
 

What is data warehouse layer?

The staging area, which is a temporary storage area used in the Extract Load and Transform (ELT) process, and the data warehouse, which is a more permanent storage place for data in a denormalized format, make up the data warehouse layer.
