  Data Quality Assurance (DQA) is the process of ensuring that the data used by an organization is of high quality and fit for its intended use. It involves a set of systematic activities that are designed to identify and correct data quality issues. DQA is a continuous process that should be integrated into the organization's overall data management strategy. The main goal of DQA is to ensure that the data is accurate, complete, consistent, and relevant. The process involves several steps, including data profiling, data validation, data cleansing, and data monitoring. Data Profiling: The first step of DQA is to profile the data. This involves analyzing the data to understand its structure, content, and quality. Data profiling can be done manually or using automated tools. It helps to identify data quality issues such as missing values, duplicate records, and invalid data. For example, a company that sells products online, the data profiling process may involve analyzing customer d...

 Data quality refers to the overall fitness of data for its intended use. It encompasses several attributes such as accuracy, completeness, consistency, and relevance. Indicators of data quality include: Accuracy: The degree to which data accurately reflects the real-world phenomena it represents Completeness: The degree to which all relevant data is captured Consistency: The degree to which data is consistent across different sources and over time Relevance: The degree to which the data is relevant to the task at hand Timeliness: The degree to which the data is current Validity: The degree to which the data conforms to the rules of the data model Uniqueness: The degree to which records have a unique identifier. It's important to note that data quality can vary depending on the specific use case and context. Therefore, organizations should establish and implement specific data quality measures and indicators tailored to their needs. Accuracy : Accuracy refers to how closely the dat...
