Understanding Core Data Concepts
Before delving into Azure services, candidates must first grasp essential data concepts. These principles act as the scaffolding for all subsequent learning and help contextualize the functionality of data tools.
Types of Data
Data manifests in several forms, each with unique characteristics and processing requirements.
Structured data is highly organized and typically resides in relational databases. Examples include financial transactions or employee records.
Semi-structured data has some organizational properties but does not fit neatly into relational tables. JSON files and XML documents are common examples.
Unstructured data lacks a predefined schema. This category includes emails, video files, images, and audio recordings. Processing unstructured data often requires advanced tools such as machine learning models.
Data Characteristics
Understanding the defining attributes of data helps professionals make decisions about storage, processing, and analysis. These characteristics are often summarized using the five Vs:
Volume refers to the quantity of data generated, often measured in gigabytes, terabytes, or petabytes.
Velocity indicates the speed at which data is produced and needs to be processed.
Variety encompasses the diverse formats and sources of data, from flat files to sensor readings.
Veracity assesses the quality and trustworthiness of data, which directly impacts the reliability of insights.
Value speaks to the potential of data to deliver business benefits when analyzed effectively.
Introduction to Databases
At its core, a database is an organized collection of data. Databases allow users to store, retrieve, and manipulate information in a structured way. Within Azure, multiple database services cater to different needs, but all follow some foundational principles.
Relational databases are based on the relational model and use structured tables. They excel in transactional systems where data consistency and integrity are critical.
Non-relational databases are more flexible and are optimized for handling large volumes of diverse and rapidly changing data.
DP-900 explores both paradigms, providing candidates with a comprehensive view of database systems and their real-world applications.
Relational Data in Azure
Relational databases have been a mainstay of data storage for decades. They are ideal for scenarios where data relationships must be preserved and transactional accuracy is paramount.
Azure offers several relational database services, all designed to minimize administrative overhead while providing scalability and high availability.
Key Concepts in Relational Databases
A relational database organizes data into tables composed of rows and columns. Each row represents a record, and each column corresponds to a data attribute.
Primary keys are unique identifiers for records within a table. They ensure data integrity and facilitate fast retrieval.
Foreign keys establish relationships between tables. For instance, an order table might contain a customer ID that links to a customer table.
Normalization is the process of minimizing data redundancy by organizing data into related tables.
Structured Query Language (SQL) is the standard language used to interact with relational databases. SQL enables users to perform queries, insert records, and update or delete data as needed.
Relational Database Services in Azure
Azure SQL Database is a fully managed platform-as-a-service offering that supports scalable, relational data storage with minimal maintenance.
Azure Database for MySQL and Azure Database for PostgreSQL provide managed environments for popular open-source database engines. These services cater to applications that require compatibility with existing systems built on MySQL or PostgreSQL.
These Azure services handle backups, high availability, scaling, and patching automatically, freeing users to focus on data modeling and application development.
Non-Relational Data in Azure
While relational databases are effective for structured data, many modern applications generate data that is semi-structured or unstructured. In such cases, non-relational databases, also known as NoSQL databases, offer superior flexibility and performance.
Azure provides robust support for non-relational workloads through services such as Azure Cosmos DB and Azure Table Storage.
Types of Non-Relational Data Models
Key-value stores associate unique identifiers (keys) with values. They are often used for caching and high-speed retrieval scenarios.
Document databases store data in flexible document formats like JSON. This model is ideal for content management systems or product catalogs.
Column-family stores organize data by columns rather than rows, making them efficient for analytical queries over large datasets.
Graph databases represent data as nodes and relationships, which is particularly useful for modeling social networks or recommendation systems.
Azure Cosmos DB
