INTRODUCTION<\/h2>\n\n\n\n

With the gushing rush of data flow, Amazon DynamoDB tutorial provides a non-SQL or non-relational database (commonly known as NoSQL) providing a mechanism for storage, processing and retrieval of data. It also allows graphs, documents, columns among its data model.<\/p>\n\n\n\n

    1.Dynamo DB?<\/h2>\n\n\n\n

    DynamoDB tutorial, being a NoSQL database, does not use the common structured query language. It provides fast and predictable performance with seamless scalability, offered by Amazon Web Services (AWS). <\/p>\n\n\n\n

    A user first stores the data in DynamoDB tables and then interacts with it through PUT and GET queries which are written and read operations, respectively.<\/p>\n\n\n\n

    DynamoDB consists of 3 basic units referred to as item, table and attribute.<\/p>\n\n\n\n

    2.Terms related to DynamoDB –<\/h2>\n\n\n\n

    The common terminologies related to DynamoDB are described as below;<\/p>\n\n\n\n

    Table, Items, Attributes<\/strong><\/p>\n\n\n\n

    1. A table is an amalgamation of rows and columns. For example; In Student Details, you will have Student Name, Student ID, Roll No., Standard and Residential Address.<\/li>
    2. A bunch of attributes in a table is called an item. For example, many attributes that uniquely define an entry inserted into a table are called an item. As an example, an item in Student Details will identify a single student.<\/li>
    3. A single field that is attached to an item is called an attribute\u2014for example, Student Name.<\/li><\/ol>\n\n\n\n

      1. Primary Key<\/strong><\/p>\n\n\n\n

      A unique attribute that is essential for the creation of a table is known as the Primary Key.<\/p>\n\n\n\n

       2. Simple Primary Key<\/strong><\/p>\n\n\n\n

      A simple primary key is also known as the Partition key, and this is in real; a single attribute. DynamoDB with the help of the Partition key\u2019s value to differentiate items inserted in the table. Example: Student ID in the Student Details table.<\/p>\n\n\n\n

       3. Composite Primary Key<\/strong><\/p>\n\n\n\n

      A composite primary key is also referred to as the Partition Key, and the Sort key having 2 elements.<\/p>\n\n\n\n

      3.DynamoDB Streams<\/h2>\n\n\n\n

      This is an add-on feature provided by Amazon DynamoDB tutorial to track any data modification events in the table in the database.<\/p>\n\n\n\n

      4.Accessing Amazon DynamoDB<\/h2>\n\n\n\n

         Accessing DynamoDB is very easy to access and can be accessed using the following methods:<\/p>\n\n\n\n
