Five types of databases ideal for Big Data

We’re talking about the ideal database types to handle Big Data. Big Data has emerged as a key IT concept in recent years. This is a term that can be applied to some very specific characteristics related to data scaling and analysis mmc996 Singapore, and it is not necessarily something that can only be used by large companies such as Facebook and Google.

The top five types of NoSQL databases

Five main types of NoSQL databases have emerged: columnar, documentary, graphical, key-value, and XML.

We are going to look at each of these five types of databases, also looking at the type of data analysis that best fits each of them.

Columnar databases

These are the most similar NoSQL databases to conventional relational databases. They store structured data in individual columns (instead of tables).

These databases use groups of columns. They work well for machine-generated data, structured data sources too large to be handled by a single computer, and for quick data queries.

If you are thinking of fast and accurate data-machine analysis, these may be the ideal database types. Apache Cassandra and Apache HBase are some of them.

Documentary databases

These types of databases are based on document storage rather than structured data.

They are good for unstructured data, such as open text from a letter or email, and semi-structured data such as academic documents.

You will have to pay attention to them if you are thinking about text analysis of documents too big for conventional databases. Some of the best known are MongoDB and Apache Couch DB.

Graphical databases

These types of databases use a graphical structure that is essentially a diagram of the relationships within the data, rather than tables.

They are good database engines for driving web applications that must provide information very quickly, such as those used for online shopping and social media platforms.

You will need to look at these types of databases if your main interest is a quick application, and you can live with some analysis approaches. Some of the best known are Neo4J from Neo Technologies and Microsoft Horton.


These are designed for simple and easy application development.

They are good for situations where you need to work with rapidly developing applications and where all other considerations are secondary. Some of the best known are Basho Technologies’ Riak and Redis.


These types of databases use the XML language, which is the underlying language of the Web and many other information exchange systems, to define the data structure.

They are good for data management that cannot be obtained with any other type of database, and a good match when you have a large amount of data in non-traditional formats, such as video and audio.

You’ll need to look at these types of databases when you need to dig deeper into unstructured data analytics like voice or video analytics. Some big names in these types of databases are Mark Logic and Sedna.

How much the playground mat cost

A play mat for outdoor toys is an essential thing for babies and small children for doing any kinds of activities. If you have a play mat, then you can allow your children to roll around on the ground and play at any time without worrying that they are unsecured on the ground surface.

A play mat is a top rated finding out tool which gives out a good pastime for the baby and helps within the growth of motor potential. You can improve the quality of child that is quite affordable and surely warranted to be loved at the growth phase of toddler.


Most Common Mistakes In A Database Design

Some of these problems are unavoidable and beyond your control. However, some of them are due to the quality of the database design.

Poor Pre-planning

If you are building a house, you would not hire a contractor and would immediately require them to start laying the foundation in an hour.

Bad design planning can lead to structural problems that would be costly to resolve once the database has been implemented.

Inadequate standardization

Database design is not a rigidly deterministic process. Two developers could follow the same design rules but still end up with completely different data designs.

That’s largely due to the inherent place of creativity in any software engineering project.

However, there are certain basic design principles that are vital to ensure that the database works optimally. One of these principles is standardization.

Standardization refers to the techniques used to disaggregate tables into constituent parts.

This is done until each table represents a single thing, while the columns describe the attributes of the element that the table represents.

Standardization is an old computing concept and has been around for more than three decades.

Bad indexing

Sometimes a user or an application may need to query numerous columns of a table.

As the number of records in the table increases, the time it takes for these queries will constantly increase.

To speed up queries and reduce the impact of overall table size, it is useful to index table columns so that the entries in each are available almost immediately when a SELECT query is invoked.

Unfortunately, accelerating the SELECT statement generally results in a slowdown of the INSERT, UPDATE, and DELETE statements.

A single table for all domain values

An all-encompassing domain table is not the best approach to database design.

Remember that relational databases are based on the idea that each object in the database is representative of one thing.

There should be no ambiguity about any dataset.

When navigating through the primary key, table name, column name, and relationships, one must quickly decipher what a data set means.

However, a persistent misconception about database design is that the more tables there are, the more confusing and complex the database will become.

This is often the reason for condensing multiple tables into one table, assuming it will simplify the layout.

This is true from an implementation point of view, but it is not the best way to design a database.

  • Small domain tables will fit on a single page on your hard drive, unlike a large domain table that will likely span multiple sections of the disk. Having the tables on a single page means that data extraction can be accomplished with a single disk read.
  • Having multiple domain tables does not prevent you from using an editor for all rows. Domain tables probably have the same underlying usage/structure.
