Database is a term used for the collection of data.There are several frameworks and models that have been introduced over the time for putting data into realistic structure.Two of the examples are relational and Object oriented database. It is about the structures that we encounter.Database management is done with the help of computer programs .These computer programs are known as Database management systems.For example,if we need to run a test on a large dataset,we can use DBMS tools to accomplish it.SQL,Oracle are the two known DBMS tools used across the industry.
We can summarize database management as a system that helps the user to interact with the database. User can perform desired operations. Moreover, it is the big thing these days.Most of the companies are working to accomplish the most optimized way of managing data.For example, Google has trillions of pages embedded in their database, but we search a query and get instant results.How is that possible? It is possible with the help of effective database management tools and structure.With the help of inverted indexes Google manage to achieve it.You can learn more about such concepts by using database management assignment help offered by us.
Relational Databases are the widely used structures in the industry.Data is organized in the form of tables. It is easy to perform operations on a tabular structure.Before you start writing your first database assignment, we would like you to learn something about RDBMS terminology.
Rows and Columns:Row is known as tuple and column is termed as an attribute.Row is a single unit of data.Column, on the other hand, is the label for an entity.For example, Date of birth, Employee ID, etc.
Keys : There is a concept of keys in databases.Foreign keys and primary keys play a vital role in uniquely identifying the rows in a database.We can see a primary key as a unique identification for a row. However, foreign key is a primary key from the another table.
Indexes: It is an interesting concept.You can understand the concept of indexed by relating it to the table of content in your book.You get to know the page number from the index and do not waste time searching the item. Similarly,the indexing in the database helps us to find a row in a short time.
