FAQ on Analytical Database System for Informed Decision Making

Analytical database stores are meant to manage big data, including business, market, retail, customer data, which has to be compiled and analyzed for business intelligence (BI) purposes. Typical analytical databases are those who are fine-tuned for optimized querying and high-level scalability. This article is made in the form of an FAQ with an objective to shed light on the missions and purposes of analytical databases in light of the modern-day enterprise data needs.

FAQ on Analytical Databases

Q1. What is Analytical Database?

At the baseline, an analytical database is a software that specializes in huge volume data or big data management for business intelligence services and applications. Databases focused on analytical purposes are effectively optimized to offer instant query response and high-end analytical features. These are also much scalable compared to the traditional databases and are often tend to be columnar databases, which are more efficient in write and read operations to and from the hard disks. Analytical databases also feature in-memory loading of the data in compressed form and help search for data through various standard attributes.

Q2. How are analytical databases used?

As we have seen, analytical databases are designed to quickly analyze huge volumes of data, which is like performing at a speed of about 1000 times faster than the operational databases. This is necessary to keep up with the demands of analytical operations. The business analysts, financial analysts, researchers, big data analysts, geospatial data analysts, data scientists, etc. largely rely on such high availability of analytical databases to handle huge data volumes.

In typical analytical databases, the historical data is compared with the current operational data. Historical data is the data, which is not real-time, but a few hours older or more than that. Contrasting operational and analytical data will help determine the best transactions and other business and research decisions.

Q3: What are some examples of data for analytical databases?

  • Market data – The historical volume and price-related data for the financial markets for devising trading strategies or financial forecasting.
  • Transactional data – Date related to past transactions, which may include the purchasing patterns for better marketing.
  • Sensor data — Date from various sensors that monitor the changes in weather, heat, cold, and so on.
  • Natural language data is the study of posts on social media, blogs, and other such content for research.
  • Process data – Study various processes to understand the logistics better and identify bottlenecks, if any.
  • Machine data – These are data related to hardware and software-generated data from different products to enhance efficiency.

Q4: What are the major differences between Analytical DB and Operational DB?

An analytical database is primarily known as OLAP or Online Analytical Processing. This is primarily used for quick processing of huge volumes of data with little or no filters. Operational databases, on the other hand, are called OLTP or Online Transaction Processing databases. These are used to look up single rows of info for easy and instant updates of a group’s daily operations.

The operational data is meant to record the business happenings. However, the complexity of analytical DBs helps to determine business strategies and make the better decision making. Operational databases contain only a transactional database, while analytical databases are meant for a more efficient and accurate data analysis. To better understand the differences between OLAP and OLTP in light of your enterprise requirements, you may get the assistance of expert service provides like RemoteDBA.com.

Q5: What are the business benefits of an analytical database?

As we can see, Interest in analytical DBs has risen largely over the last one and a half-decade as there is an increasing number of data analysis tools are coming up. Combined with these tools, analytical databases can enable real-time data processing from various sources as IoT connected devices, mobile devices, biometrics devices,remote sensors, video streaming, and media software, etc.

Q4: What are some of the higher-level analytical database benefits to mention?

Here are some of the high-level benefits of analytical databases.

  • Columnar storage – Column versus row-based database design allows for a very quick and easy analysis of larger data sets within a column. The traditional row-based structure is not that easy to scale up for larger data volume as the way how column-based DBs can do it.
  • Better data compression – Columnar database design of the OLAP databases offer the most efficient version of data compression, which is how the database space and speed can be maximized.
  • Distributed workloads – Data can be stored on a cluster of servers, which are also called the nodes. When data gets stored across different servers set parallel, the queries can be processed throughout the cluster. This will enable more efficient and quicker processing of huge volume datasets.

Some other high-level analytical databases’ benefits include horizontal scalability, SQL compatibility, advanced statistical functionality, etc.

Q5: Spreadsheet of the doc?

The primary question to answer is the nature of the data you handle. If you see a very clean and logical connection (between the equivalent columns and rows as in a spreadsheet), you probably think of a relational DB. Relational databases are ideal when you know about each piece of data that fits all other data types. MySQL, BigQuery, Amazon Redshift, PostgreSQL, etc., are ideal relational DBs to consider.

On the other hand, if you see that your data follows less logical patterns, but is focused more on the flow, like in the case of a document, you have to think of a non-relational DB. If you have the additional requirement to perform analytics on the data like podcasts, social media, GIS info, or email, etc., then these sorts of analytical tasks can be better handled by the non-relational DB, which offers a lot of data points to mine from. MongoDB and Apache Hadoop etc., are solid nonrelational databases.

After figuring out all the primary needs, you also need to consider the type of data you handle and how much data you need to analyze. As a rule of thumb, the non-relational databases can work the best with larger sets of data. The non-relational DBs are not structured in the conventional rigid row-column design of the relational DBS, so they can easily read and write a huge amount of data quicker.
