The work of a data analyst involves working with data throughout the data analysis pipeline. This means working with data in various ways.
The primary steps in the data analytics process are data mining, data management, statistical analysis, and data presentation. The importance and balance of these steps depend on the data being used and the goal of the analysis. Data mining is an essential process for many data analytics tasks. This involves extracting data from unstructured data sources. These may include written text, large complex databases, or raw sensor data.
The key steps in this process are to extract, transform, and load data often called ETL. These steps convert raw data into a useful and manageable format. This prepares data for storage and analysis. Data mining is generally the most time-intensive step in the data analysis pipeline.
Data warehousing involves designing and implementing databases that allow easy access to the results of data mining. This step generally involves creating and managing SQL databases. Non-relational and NoSQL databases are becoming more common as well. Statistical analysis is the heart of data analytics. This is how the insights are created from data. Both statistics and machine learning techniques are used to analyze data. Big data is used to create statistical models that reveal trends in data.
These models can then be applied to new data to make predictions and inform decision making. Statistical programming languages such as R or Python with pandas are essential to this process. In addition, open source libraries and packages such as TensorFlow enable advanced analysis.The International Conference on Big Data Analytics and Data Science provide an international forum for the presentation of original research results, as well as exchange and dissemination of innovative, practical development experiences.
