Advantages and Disadvantages of SQL

It is not an extreme case, for example many web apps allow to customize the table name prefix at installation time. SQL databases can be more secure than other database options because they use a structured data model. This means that it is easier to control access to data and ensure that it is protected. SQL also supports encryption, which means that you can encrypt data to protect it from unauthorized access. Finally, SQL databases can be audited, which means that you can track who has accessed data and when. One of the biggest disadvantages is that it can be difficult to scale.

Pros and cons of SQL

SQL is also compatible with many big data tools, which means that you can use it to manage data across different platforms. SQL also supports parallel processing, which means that you can analyze large amounts of data quickly. A significant benefit of NoSQL is that you don’t have to define a schema upfront (or ever). This makes it easy to add new columns without dealing with all the issues involved in altering a vast table with lots of data already in it. Regarding support, you’ll generally find that more help is available for SQL databases than NoSQL. This is because SQL is a more established technology and thus has many more users and developers who can help you with your problems.

When to use SQL vs NoSQL

Despite the presence of the international standard ANSI SQL-92, many companies engaged in DBMS development make changes to the SQL language used in the developed DBMS, thus deviating from the standard. With SQL, the programmer only describes what data should be extracted or modified. The way of doing this is decided by the DBMS directly when processing the SQL query. However, one should not think that this is a completely universal principle – the programmer describes the data set to be extracted or modified, but it is useful to imagine how the DBMS will parse his query text. The more complex the query is designed, the more writing options it allows, varying in execution speed but equal in the final data set. The absence of these properties makes the data stored in a NoSQL database less trustworthy than those stored in SQL databases.

  • On the plus side, they are more scalable than traditional relational databases and can store a variety of formats.
  • You can intelligently monitor, tune, and manage large-scale PostgreSQL installations from a single GUI console.
  • With helping of rich transactional support, SQL programming is capable to keep manage the enlarge records and other numerous transaction.
  • Due to some hidden corporate term and conditions, SQL doesn’t allow developer the fully control over the databases.
  • All these factors have a direct impact on your business performance.
  • Disabling SQL Browser only prevents name resolution, but instances can still be found by port.

SQL is used by many different types of organizations, including businesses, governments, and nonprofits. It is commonly used for tasks such as storing customer information, tracking inventory, managing financial records, and analyzing data. I like long explicit when to use NoSQL vs SQL table names (it’s not uncommon to be more than 100 characters) because I use many tables and if the names aren’t explicit, I might get confused as to what each table stores. I have done some tests using them vs. not and have seen some processing gains.

While it may be a comparatively simple programming language to learn, SQL also suffers from having a steep learning curve at first. This is partly a result of the superficial complexity of query structures, and the possibility for a lot of variety in the way that certain actions are completed. Obviously, if you’re looking for a non-relational database setup, a different approach is needed, but for straightforward data storage and transformation, SQL ticks all the boxes.

Pros and cons of SQL

While SQL calls for ACID properties, NoSQL follows the CAP theory (although some NoSQL databases — such as IBM’s DB2, MongoDB, AWS’s DynamoDB and Apache’s CouchDB — can also integrate and follow ACID rules). Generally I try and abbreviate the table name to 1 or 2 representative letters. You need them if you’re going to join a table to itself, or if you use the column again in a subquery… Microsoft SQL’s query optimiser benefits from using either fully qualified names or aliases. If you have column names that occur in more than one table, specifying the table name as part of the column reference is a must, and thus a table alias will allow for a shorter syntax.

Declaracy of PROS AND CONS

Also, NoSQL supports a denormalized data model which allows all the information to be stored in a single record. And since the multi-row transaction is not a mandate today, updating multiple rows is not required. This puts less load on the system thus giving a boost to the performance. PostgreSQL has fewer GUI options than MS SQL Server because it is mostly based on the Linux and Unix operating systems and on command platform consoles.


The drawbacks, however, make it highly unsuitable for certain types of projects. The main problem with SQL is that it is very difficult to scale as much as a database grows larger. The data type is defined as the type of data that any column or variable can store in MS SQL Server. 5 Database management trends impacting database administrationIn the realm of database management systems, moreover half (52%) of your competitors feel…

Advantages and Disadvantages of SQL

It’s a powerful language that can help you do many data-related things but also has some downsides. NoSQL databases offer horizontal scalability, meaning that more servers simply need to be added to increase their data load. This means that NoSQL databases are better for modern cloud-based infrastructures, which offer distributed resources. In addition to supporting data storage and queries, they both also allow one to retrieve, update, and delete stored data. However, under the surface lie some significant differences that affect NoSQL versus SQL performance, scalability, and flexibility.

Pros and cons of SQL

Also, I’ll compare PostgreSQL and MS SQL Server databases for each factor. Instance hiding has the advantage of making the instance completely invisible to unauthorized users querying SQL Server. They cannot enumerate or discover hidden instances through any means. Selecting or suggesting a database is a key responsibility for most database experts, and “SQL vs. NoSQL” is a helpful rubric for informed decision-making. When considering either database, it is also important to consider critical data needs and acceptable tradeoffs conducive to meeting performance and uptime goals.

Pros and cons of SQL

SQL is an open-source programming language that allows to build (RDBMS) relational database management systems. Thus, it is great solution for developers who are seeking for a community of professionals to learn from off. With over four decades of presence, Structured Query Language (SQL) works with relational database management systems (RDBMS). It is the traditional way of creating databases and managing large volumes of data.

NoSQL is absolutely worth using, providing the circumstances are appropriate. Using a hammer with screws, or a screwdriver with nails, tends not to work very well. NoSQL databases provide abilities that traditional relational databases cannot. They are useful for handling large amounts of data for research and development purposes and should be selected based on the needs of the organization and the project. Because NoSQL databases can store data in their native formats, developers aren’t required to adapt the data for storage purposes. By storing data “as it is,” a front-end ETL process is no longer necessary to modify semi-structured data so it can be placed in the row and column formats supported by SQL.
