海外TECH	DEV Community	What is the difference between SQL and SQL Server (and similar tools)? 😇🎉	https://dev.to/aashish/what-is-the-difference-between-sql-and-sql-server-and-similar-tools-3n3o	What is the difference between SQL and SQL Server and similar tools Hey people I am a programmer and have been one since last years I completed my B Tech degree back in and I must admit I was not particularly a big fan of DBMS somehow I managed to complete the course and secure passing grades I know it is an important subject but it never appealed me as much and therefore I never took as much interest I always felt guilty of it As established it is not an epiphany for me that it is an important subject and I must get my hand dirty with it so I decided to pursue it and complete at least projects in the next couple of weeks This way sans Big Data I am slowly working on that too I will have all my grounds covered as a full stack data scientist Thats enough about me now lets literally get to the title of this blog post I know many beginning with SQL will have this question in mind So here I am explaining the basics as I learn Please feel free to point out anything you feel should be corrected I ll appreciate the feedback Lets first get to know what SQL is in brief Definition SQLBy definition SQL Structured Query Language is a query language It is generally used with Structured Databases or for processing data streams in real time in relational data stream management system to query manipulate the relational database data GotchaSo basically SQL is a language As this is a language and a quite popular one there are various dialects of this language And anyone familiar with computers or even remotely acquainted with how computer works will know a language needs some kind of environment to be executed in It is environment that interprets the commands of the language identifies different dialect and executes the command particular to the dialect Let s park this environment concept for now and we will come back to it later in this post Let s talk about SQL a little more SQL comprises of major sub languages Data Definition Language DDL to create and modify the structure of the databaseData Manipulation Language DML to perform read insert update and delete operations on the data of the databaseData Control Language DCL to control the access of the data stored in the databaseDefinition SQL ServerSQL Server is proprietary software or an RDBMS tool that executes the SQL statements It also provides some additional features and functionalities so that the user can properly interact with the database and can perform all the database operations efficiently GotchaSo basically it is a database software It uses SQL as a language to query the database The popular ones include MySQL SQL Server Oracle Informix Postgres etc They are mix of open source and proprietary software available to use I hope that clarifies your doubt and you are good to go ahead and understand which to use where It should also make you clear with what you are using and what are different softwares you can compare I know I haven t been quite comprehensive with the list but then which softwares we use actually depends on the requirement which concerns security control features compatibility with the server or the source of distribution People who know more about it please share your opinion through the comments Thanks until next time	2021-07-11 12:39:30
海外TECH	DEV Community	useLocal: the useState hook for a properly-synced state	https://dev.to/theluk/uselocal-the-usestate-hook-for-a-properly-synced-state-32kp	useLocal the useState hook for a properly synced stateAs you might know the React hook useState takes one argument which will initialize its internal state to that given value When React with Hooks got released I found it a little bit confusing but it perfectly makes sense No matter what there are still situations where you need to update the state based on the incoming props Usually that is done using a useEffect hook where you listen on the incoming prop to change and then update your local state This is a great way of handling it because you as the owner of the component can perfectly control if the parent prop change is actually what you want It could even break your component if the parent decides to update a prop during a critical state of your component But there are also situations where not much can happen There are simple scenarios where you basically want to hold a local version and not propagate it up the tree until a certain condition happen During that time you still want to allow the parent controlling component to update the local value if that is what it wants Here is an example how to allow the parent controlling component set and update if necessary the from and to values It can happen that for example for whatever reason there is another component that can set a date range for that we would want that from and to can be updated const RangeDatepicker value from to onChange gt const from setFrom useLocal from const to setTo useLocal to const update gt if from amp amp to onChange from to useEffect update from to return lt MyCalendarRangePicker from from to to onChangeFrom setFrom onChangeTo setTo gt the easiest implementation of such a hook in Typscript looks like this One further improvement would be to pass in some conditional function that checks if it is allowed to update the local state You can visit the gist here	2021-07-11 12:28:56
海外TECH	DEV Community	The Four Stages Of Full Software Testing	https://dev.to/jarjanazy/the-four-stages-of-full-software-testing-2fgp	The Four Stages Of Full Software TestingTesting software is crucial to assure that it does what we expect it to do and to catch problems as early as possible to speed up the development process The process of testing can be divided into stages starting from writing code and ending with deploying to production ️⃣Commit StageThis includes tests that fail fastA total run time of minutes or less is preferred What kind of tests Unit testsTesting isolated units of behavior Controller testsFor example Given that we send a POST request to this endpoint it should fail because the parameters are invalid Database testsFor example Given those records in the DB this method should get them Coding standards testsThis test fails because at file X you have empty lines ️⃣Acceptance Stage What kind of tests Acceptance testsFor example When user X logs in and orders a new book we should create a new order request and send an email Performance tests Configuration tests Any other tests that we want to run prior to release ️⃣Release StageThis stage comes after building the software and attaching all its components together What kind of tests Smoke testTest the system s most important features Sign in book purchase etc Canary release testingReleasing the new version of the system to places of low impact For example Netflix uses Canary releasing by releasing new updates to geographic locations in the world where it s AM so if any failure happens only few people experience it Exception tracking ️⃣Product StageThis stage is executed after the system is deployed to production and is under use What kind of tests Can it scale up down Is it using a lot of memory disk CPU What is the request response time Do performance metrics match predications Security For example Netflix has teams to test those aspects and try to break the system Chaos monkeys Latency monkeys Security monkeys This material in this post is mainly derived from Dave Farley amazing video on testing	2021-07-11 12:21:27
