Study Notes
- Data management involves collecting, storing, organizing, and maintaining data within an organization
- Effective data management supports decision-making and strategic planning for executives and managers
- The data management process comprises various functions to ensure data is accurate, available, and accessible
- User involvement is crucial in the data management process
Key Parts of Data Management Process
- Data architecture is designed and deployed with database systems and repositories for organizational data
- Data is generated, processed, and stored in databases, file systems, or cloud storage
- Data quality checks identify errors and inconsistencies for resolution through data cleansing
- Data models map workflows and relationships in data sets to organize information for business needs
- Data from transaction systems and other sources is integrated in data warehouses or data lakes for analysis
- Data governance programs establish data definitions and usage policies for consistency across systems
Data Management / Databases
- Data is organized into table-like structures called files, related by common fields
- Forms facilitate user input into databases, while queries retrieve data
Data Management / Data Warehouses
- Data warehouses store data extracted from various databases, including historical data
- Advanced math techniques are employed to process large volumes of data
- Data mining involves searching, retrieving, and analyzing data to discover patterns and trends, like in "Market Basket Analysis"
- Multidimensional databases and cubes are used instead of flat tables
Data Management Process
- The Data Management Process consists of Data Collection, Data Preparation, Data Storage, Data Analysis and Data Distribution
Data Analysis
- Data analysis transforms data into useful information
- Tools used for the analysis include Excel, Python, R, Tableau, and Microsoft Power BI
Data Analysis with Spreadsheets
- Spreadsheet software like Excel performs data analysis on smaller datasets collected through transactions
- Spreadsheets organize data in flat (2D) files with rows and columns
- Spreadsheets organize data, perform calculations and visualize data in charts
- Advanced tools like Solver, Pivot tables, and Power Query enhance spreadsheet analysis for complex data
Big Data
- Big Data refers to unstructured, constantly changing data from diverse sources, needing cleaning before use
- Big data has the characteristics of volume, variety, and velocity
