What is Microsoft SQL Server?

SQL Server is a popular Relational Database Management System. It was developed by Microsoft and launched on April 24, 1989. It was written in programming languages C and C++. It follows a relational model architecture that was invented by E.F.Codd. 

The Relational Model stores the data in a structured format and generates relations between each table. The data is organized in the form of rows and columns where the column represents an attribute or feature and the row represents the value or record.

SQL Server comes in many versions, each with a slightly different feature set and query limits. The versions are Express, Enterprise, Standard, Web, and Developer

In case you want to install SQL Server, you may click here and download a version as per your system requirements.

Key Features of SQL Server

• Cloud Database Support: Microsoft SQL Server is readily integrable with Cloud applications like Azure and Microsoft SQL. all the versions have in-built security and data management tools. This cloud support enables the data to be readily available and allows for better management in case of failures.
• Ease of Management: Microsoft SQL Server uses the Kubernetes for its server management and deployment. It can be easily combined with Windows and Linux operating systems. 
• High-Security: SQL Server meets all the Data Security regulations. It also has a high level of encryption to data that is added. Tables can be protected using passwords and also has access control options. 
• End-to-End Business Data Solutions: SQL Server offers an end-to-end solution for business data. It offers tools for Data Administrator, ETL solutions, Data Mining, and many others.

Methods to Migrate Data from Amazon S3 to SQL Server

Data can be migrated from Amazon S3 to SQL Server via two different methods. 

• Method 1: Migrate Data from S3 to SQL Server via AWS Services
• Method 2: Automated S3 to SQL Server Migration using Hevo Data

Method 1: Migrate Data from S3 to SQL Server via AWS Services

• Step 1: Create an AWS S3 Bucket
• Step 2: Add Sample Data as CSV Files in S3 Buckets
• Step 3: Configure SQL Server Database Tables & Objects 
• Step 4: Create the IAM Policy for accessing S3
• Step 5: Push Data from S3 to SQL Server Instance

Step 1: Create an AWS S3 Bucket

• Log in to your Amazon Console. 
• Click on Find Services and search for S3.

• Now, click on the Create Bucket button.
• Enter the bucket name and select the region.

• Click on the Create Button. 
• Search for the Bucket, and check for access. It should not be public.

Step 2: Add Sample Data as CSV Files in S3 Buckets

• Create a file “employee_Hevo.csv.”
• Add the following components:

Employee_Id,Employee_First,Employee_Last,Employee_Title
1,Jane,Doe,Software Developer
2,Vikas,Sharma,Marketing
3,Rajesh,Kumar,Project Manager
4,Akshay,Ram,Customer Support

• In the S3 console, select the bucket name you just created. 
• Click on the upload option and follow the onscreen instructions.

Step 3: Configure SQL Server Database Tables & Objects

• Open SQL Server Management Studio and run the script below or create a similar table.

CREATE TABLE [dbo].[Employees](
[Employee_Id] [int] IDENTITY(1,1) NOT NULL,
[Employee_First] [varchar](25) NULL,
[Employee_Last] [varchar](25) NULL,
[Employee_Title] [varchar](50) NULL,
CONSTRAINT [PK_Employees] PRIMARY KEY CLUSTERED
(
[Employee_Id] ASC
)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

Step 4: Create the IAM Policy for Accessing S3

• Before the data is migrated from S3 to SQL Server, you need to set up IAM policies so that the bucket you created earlier is accessible.
• Click on AWS search and search IAM.

• In the policies section, click on create policy

• Click on the choose a service button to search for S3.

• Complete and fill all the access levels and parameters.

• In the resources tab, select the bucket name and click on the Add ARN button. Enter the bucket name.

• Add the CSV file by specifying the ARN.

• Go to the review policy section and click on Create Policy.

• Create the IAM role to use the policy. Open the AWS Console, and go to IAM. Select the Roles tab. 
• Click on create the role. Follow the below mentioned order:
  • AWS service (at the top.)
  • RDS (in the middle list, “select a service to view use cases”.)
  • RDS — Add Role to Database (towards the bottom in the “Select your use case” section.)
• Click on the next: permission button. Attach the permission policies by entering the name of the policy.
• Follow the instructions on the screen. Click on review role, enter the values and then click on create the role. 

Step 5: Push Data from S3 to SQL Server Instance

• Open the AWS Console and click on RDS.
• Choose the SQL server instance name to load data from S3 to SQL Server.
• In the security and connectivity tab, select the IAM roles and click on Add IAM Roles.
• Choose S3_integration in the feature section.
• Click on Add Role button.

Limitations of a Manual Approach

• The manual method for loading data from S3 to SQL Server requires a lot more technical expertise.
• There are many steps involved in the manual method for S3 to SQL Server and in case a step gets mixed up, all the steps need to run from the start. 
• Creating IAM roles and access control is difficult.
