Difference Between GraphDB and RDBMS (With Table)

The technology regarding databases has garnered a huge expansion over the years and options are innumerable. The top contender for NoSQL is GraphDB. It has the adoption of enterprise for some time and answers some of the most intense questions using data that is very hard to interpret.

GraphDB vs RDBMS

The difference between RDBMS and GraphDB is that in certain situations data model is far too easy to change in some situations in graph databases than in RDBMS. For example, if RDBMS to change a relationship in the table a DDL should be applied with downtime potential.

GraphDB is a database in which structure of graph used to represent data. It uses graphs for a detailed knowledge and query with nodes and edges that are a part of it. It store data in a sorted fashion. The main interpreter is the graph. GraphDB is considered as a NoSQL database and primarily does data storage in form of a network graph. GraphDB is primarily composed of edges and nodes. Nodes signify entities that are specific while Edges mean the connection between the latter.

RDBMS has some pros in some areas like control of data and sorting of data is defined and also the aggregation of data is good.  RDBMS is the data storage that occurs in form of relational tables. The tables are comprised of rows and columns in which each row has a key so they can be connected to a specific row.

Comparison Table Between GraphDB and RDBMS

What is GraphDB?

GraphDB is specially built for navigation and storage. The value of databases of graphs resides in relationship building. These databases have storage of data via the nodes incorporated in them. They also have edges that are used for entity storage. The edge has the following things a starting node, node for the end, type, and direction. There is not a certain limit for a node to form an interlinking relationship particularly.

In GraphDB the relationship or joint is extremely quick as the relation is not evaluated during the time of query and is kept in the database. The advantages of GraphDB in fields like social networking, engines for a recommendation, detection of frauds especially when the need for creating of relation is needed in a hurry and quick query is needed.

Properties of GraphDB

  1. They incorporate a start node and also an end node.
  2. The graph is made a directed graph.
  3. The graphs are quite agile and new data can be incorporated in already the one that exists and that too without any functionality loss.

What is RDBMS?

RDBMS goes by the full form of the relational database management system. The model; can be presented and comprise of rows and columns. It is the inclusion of components like:  

  1. Table
  2. Record or Tuple
  3. Field
  4. Domain
  5. Instance
  6. Schema
  7. Keys

The table can refer to the data evaluated and collected and then represented in form of rows and columns. The table goes by a different name in each database. The row of the respective table goes by the name record. It can also be referred to as a tuple. The field is the heading of the column or a row. The domain can be said as the values that are permitted for a particular attribute.  If the value is beyond the domain attribute then the value cannot be accepted.

Properties of RDBMS

  1. Atomic values
  2. Presence of unique rows
  3. Values in column are of same data
  4. The column is comprised of the new name
  5. Consistency is maintained in multiple tables via integrity constraints.

Main Differences Between GraphDB and RDBMS

  1. As GraphDB is growing at a staggering rate it is important to distinguish between GraphDB and RDBMS. Both GraphDB and RDBMS has a prime focus on data relation. Each of these has its unique pros and how they interlink data between them.
  2. In GraphDB storage of data is in form of graph while in RDBMS the storage is done in form of table.
  3. One of the main differences between RDBMS and GraphDB is the entity-relationship and the storage.
  4. GraphDB has presence of nodes whereas RDBMS has presence of rows,
  5. In GraphDB record and relation is done in a separate manner and that too individually while in RDBMS structures are already defined initially.
  6. In a GraphDB the storage of relation is done at a level that is the isolated and individual level while in RDBMS there is the involvement of table definitions and at a high level.

Conclusion

By the above-mentioned properties and features of both databases, it can be concluded that each database has its ability and advantages in its own way. RDBMS shows data in a sorted manner that is in rows and columns while GraphDB shows data in a completely different manner and which is in form of graphs of three different types. Although it’s not for everyone as these graphs need a complex understanding. RDBMS is not concerned with the integrity or a structure but it only deals with data that can significantly improve the overall performance of the model.

GraphDB is very agile and flexible in its way compared to the RDBMS. GraphDB has a performance that is on a higher level especially for analytics whereas RDBMS has significantly poorer performance for analytics that are deep. The GraphDB is agile and very flexible than the RDBMS as the performance is higher and better for transactions that are not easy to interpret.
