Database Design and development

Database Design

For any business process where the data need to be stored for later analysis or just for maintaining inventory or record, one need to maintain the day to day transactional data management. 
For small business any approach used will work, like maintaining sheets, or csv all will work, but for mid scale or large scale companies data management is important to be done in database, since data could be fetched from different sources sometime it could be any frontend website or it may be any mobile application or computer software etc.
Management of these set of information in a structured or say tabular format is known as database management. 
Basically it categories in two types relational database and nosql database.

For relational database software used are like SQL server, oracledb, azureSQl, MySQL etc.

For nosql database we have format files file json or XML etc.

Generally relational database management system is something which is widely used because of its reliability, consistency, security and optimization features.

Now let's discuss the database design:-
To design any database first the business requirements as well as the different data component of business need to be studied then only proper designing is possible.

After having the business requirements, one can note down all the related table entities and there information attributes, then normalisation process can be applied on the entities to get the final set from it.
Relationship between the tables are important to understand and configure since it will maintain a data integrity between related tables. After doing this now scripting for tables could be done using any SQL langauge and then finally the script could be executed on the server.

Obviously optimization and testing of table in database is another set of important properties need to be discussed.

How to be a DATA Analyst

To become a data analyst one need to be good at maths, basically numbers and visuals are two things every data analyst must know about. In my experience I believe domain knowledge and understanding the business is one of the key factor one would be needing to sort out pattens or analysis from the business data. Until and unless I don't know what my details is telling to me how I can be sure what to analyse. After all these basically a series of tool is important so that the work of analyst becomes easy, let's say tools like Excel, SQL , visualisation (tableau, powerbi), cloud computing (azure,AWS), modules in python like matplotlib, scikit learn, seaborn, pandas are some of the basic necessities that need to be fullfill. Some guidelines if I have to say is: 1) always try with clean data, then move to dirty data(mostly wrong columns values, mismatch column values, redundant data) 2) making quick visuals are always a better approach to increase confidence and skill in the path 3)...

SQL Interview Question

  SQL Interview Question: You are given two unrelated tables: Product — containing product details ProductSubcategory — containing subcategory details There are no common columns , and no foreign key or primary key relationships between them. Task: Write a SQL query to perform a join between these two tables, despite having no direct relationship. Query And Related Table: The problem with the above script is when you have exact match between the "product description" column and "subname" column then this code will work, but let say you have difference like Gadget and Gadgets then in this case the query will fail.  Feel free to post you comments over this solution, my approach would be: 1) Do the match over the letter by letter then count the total letter matched and then total letters if the percentage for this is above 80% then this record must be in the join condition. Basically perform the lookup with the help of SQL code. 2) Make abridge...

HTTP request to get data import into Database

What is HTTP request? It's a logic that can be used in order to pull data using api's created by individuals both private and public. Some API's are build in house to use it for own use and some are public API's, there are series of methods that can used in order to fetch data using these public API's. Let's see some of them: 1) GET: it is used to request some data from the frontend, usually the website URL, access token is required and in the URL itself the path is specified that someone is looking for. Let's understand with an example:- For a college website xyzuniversity.com, if I need to call the record for a student name "Alex" I will be writing the URL like GET http://university.com/student-record/alex:? And in the response I will be getting the associated record in JSON format. Here we used the GET method to call this data, like this we got multiple methods like PUT, HEAD, DELETE, PATCH,OPTIONS etc that can be used based on the need. Let...
