Study Notes
Active Storage Systems
- Student information is stored in a student information system (SIS) or student records system (SRS) that allows immediate access and enables various functions such as admitting, advising, and registering students, recording grades, and storing student records.
- The system can be accessed by multiple users simultaneously, with rules created to allow access based on roles and responsibilities.
- Retention requirements must be considered when selecting a storage medium, with different retention periods for various types of records (e.g., admission records: 10 years, grade records: permanent).
Structured, Unstructured, and Semi-structured Data
- Structured data refers to data that is highly organized, easily searchable, and easily mined, such as database data.
- Examples of structured data include Nutrition Facts labels on product packaging and database records.
- Unstructured data accounts for 90% of new enterprise data, has no well-defined model or schema, and includes forms such as emails, social media posts, and images.
- Semi-structured data has some level of organization, but does not conform to a formal structure, such as HTML and XML documents.
Relational Database Management Systems (RDBMS)
- RDBMS store data in collections of tables (entities) with columns (properties) and rows (records).
- Relations are defined between tables for cross-referencing using a primary key.
- Data can be pulled from multiple tables to create a record using structured query language (SQL).
Unstructured Data
- Unstructured data is a significant challenge for organizations, and business intelligence applications and technologies can be employed to gather, store, analyze, and provide access to this data.
- Examples of unstructured data include emails, social media posts, text messages, business documents, and videos.
Non-relational, NoSQL Database
- Non-relational NoSQL databases do not use structured tables, instead using flexible schemas for unstructured data storage.
- Drawbacks of non-relational databases include less control over consistency and data relationships.
Semi-structured Data
- Semi-structured data has metadata attached that describes content, such as SharePoint lists, document libraries, and project and team sites.
- Examples of semi-structured data include XML documents, e-commerce transactions, and server application programming interfaces (APIs).
Big Data
- Big data refers to data that is too large to process with traditional database and software techniques.
- Characteristics of big data include volume, variety, velocity, veracity, value, and variability.
- Organizations can incorporate big data techniques into their existing architecture, such as using radio frequency identification (RFID) tags to track products.
Data Warehouses, Marts, Lakes, Lakehouses, and Hubs
- A data warehouse is a central repository of preprocessed, structured data for analytics and business intelligence.
- A data mart is a smaller version of a data warehouse that serves specific business units.
- A data lake is a centralized repository that allows storing all structured and unstructured data at any scale.
- A data lakehouse combines big data analytics and performance metrics.
- A data hub is used for controlled data-product distribution.
