海外TECH	DEV Community	My First Month in the SCA Cloud School: A journey of Learning and growth.	https://dev.to/jeptoo/my-first-month-in-the-sca-cloud-school-a-journey-of-learning-and-growth-1a5g	My First Month in the SCA Cloud School A journey of Learning and growth I ve always been fascinated by the field of SRE and the crucial part it plays in maintaining the availability and smooth operation of digital services Despite the fact that I had no prior expertise in SRE I had worked in software engineering for a while and had witnessed firsthand the value of having a solid infrastructure I came across the She Codes Africa SRE boot camp sponsored by Deimos which was an ideal chance to expand my knowledge of SRE tenets and best practices when I learned about it The program s focus on practical knowledge and abilities as well as its reputation for producing excellent SREs attracted my attention in particular The program began on st of March and it runs for two months There are evaluations and projects that are to be covered during this period I will break down what I have learnt during the first four weeks WEEK ONEWe were introduced to cloud computing and AWS fundamentals including the different cloud deployment models and AWS services such as EC S and IAM We learned how to set up an AWS account create an EC instance and configure it with appropriate security settings We further explored on security best practices for AWS resources such as access control policy and monitoring I had an opportunity to practice my skills by creating an EC instance and writing and article about it you can check it out hereBy the end of week one I had a solid understanding of cloud computing and AWS fundamentaals and I had gained practical experience with creating and securing an EC instance WEEK TWOWe learned about Azure and its concepts including the architectural components of Azure and how to create an Azure account We explored further into Azure core services which included Azure compute services storage services Azure analytics Azure databases We delved into core solutions and management on Azure where we learnt about IoT services AI services serverless technology and management and configuration on Azure environment We finally learned about monitoring services for Azure and how to use them to keep your Azure resources secure and performant By the end of the second week I had a full understanding of Azure s services and how to manage them effectively I then wrote an article on how to create an Azure App Service to host the web applicationWEEK THREELearned about the general security and network security features on Azure including how to protect against threats and secure network connectivity We explored Identity governance privacy and compliance features on Azure which are essential for maintaining the security and compliance of your Azure resources We also learned about Azure cost management and service level agreements SLAs which are critical for managing your Azure resources effectively and ensuring that you are getting the best value for your money Finally we deployed a virtual machine on the Azure portal which gave me hands on experience with creating and managing Azure resources I also wrote an article on How to Deploy a virtual machine on Azure portalAt the end of week three I gained clarity on how to secure Azure resources and manage their cost effectively I practiced creating and managing a virtual machine on Azure portal WEEK FOURWe were introduces to SQL and learned about its fundamental concepts and how it is used in the context of Azure Learned about deployment and configuration of servers instances and databases for Azure SQL which involved creating and configuring SQL instances and databases on the Azure platform We practiced connecting user created instances to SQL Server Management Studio SSMS which is a crucial tool for managing and querying SQL databases We learned how to backup and restore databases using SSMS which is essential for ensuring data integrity and recoverability We explored on how to secure data using Azure SQL including data encryption and access control measures Finally you learned how to deliver consistent performance with Azure SQL which is critical for ensuring that your SQL databases are fast and reliable By the end of week four I had solid understanding on Azure SQL and how it is used in the context of Azure CONCLUSIONThe first four weeks of the She Codes Africa SRE boot camp have been a fantastic experience for me I have learned a lot about cloud computing Azure general security network security SQL and database management and I have gained practical experience with creating and managing cloud resources on Azure I am now looking forward to the next phase of the boot camp where I will deepen my knowledge of cloud technologies and gain more practical experience with using them One of the things that have impressed me the most about this boot camp is the amazing community of learners and facilitators that I have had the privilege of interacting with The community is incredibly supportive and always ready to help each other out which has made the learning process both enjoyable and productive The facilitators are also knowledgeable and experienced and they have provided excellent guidance and feedback throughout the boot camp As a woman in tech I would like to recommend She Code Africa to other women who are interested in cloud computing and want to gain practical experience with using cloud technologies SCA is a fantastic organization that is committed to increasing the number of women in tech and providing them with the support and resources they need to succeed I am grateful for the opportunity to be part of this boot camp and I am confident that the skills and knowledge that I am gaining will be invaluable in my future career as an SRE	2023-05-01 21:23:48
海外TECH	DEV Community	Understanding Primary Keys, Foreign Keys, and Constraints in SQL	https://dev.to/jolamemushaj/understanding-primary-keys-foreign-keys-and-constraints-in-sql-22co	Understanding Primary Keys Foreign Keys and Constraints in SQLSQL stands for Structured Query Language which is a standard programming language used for managing relational databases It is used to create modify and retrieve data from a database as well as to manage database objects such as tables views indexes and stored procedures Important concepts in SQL databases that are used to establish relationships between tables and ensure data integrity are primary keys foreign keys and foreign key constraints A primary key is a unique identifier for a row in a table It is a column or a combination of columns that uniquely identify each row in the table Primary keys are used to enforce entity integrity which means that each row in the table must be uniquely identifiable A foreign key is a column or a combination of columns in one table that refers to the primary key of another table It can be used to ensure referential integrity which means that the values in the column or columns that refer to the primary key of another table must match one of the values in that primary key A foreign key constraint is a rule that enforces referential integrity between two tables It specifies that the values in a foreign key column or columns must match one of the values in the primary key of another table and can be used to ensure that data is consistent and accurate across multiple related tables Here s a simple example to illustrate the concepts of primary keys foreign keys and foreign key constraints in SQL databases Suppose we have two tables customers and orders The customers table has columns for customer id name and email and the orders table has columns for order id customer id date and total To establish a relationship between the two tables we can define the customer id column in the customers table as the primary key and the customer id column in the orders table as the foreign key Here s the SQL code to create these tables and define the primary key and foreign key constraints CREATE TABLE customers customer id INT NOT NULL PRIMARY KEY name VARCHAR email VARCHAR CREATE TABLE orders order id INT NOT NULL customer id INT NOT NULL date DATE total DECIMAL PRIMARY KEY order id FOREIGN KEY customer id REFERENCES customers customer id In this example the customer id column in the customers table is the primary key which means that it uniquely identifies each customer in the table The customer id column in the orders table is the foreign key which refers to the primary key in the customers table The foreign key constraint is defined using the REFERENCES keyword which specifies that the customer id column in the orders table references the customer id column in the customers table This constraint ensures that each order in the orders table is associated with a valid customer in the customers table So when we insert data into the orders table the foreign key constraint ensures that the value in the customer id column matches one of the values in the customer id column in the customers table If the value in the customer id column does not match a valid value in the customers table the foreign key constraint will prevent the data from being inserted ensuring that the data is consistent and accurate across both tables	2023-05-01 21:22:09
