Data structure and tables

Now that we have an idea of ​​the salient features of SQL Server and PostgreSQL, let’s dive deeper into the differences between the two. You can use the factors mentioned below to identify which database management system best suits your needs.

Availability
PostgreSQL offers a wide range of solutions to ensure high availability for users, such as write-ahead log shipping, shared disk failover, data partitioning, and various replication methods. Tools such as EDB Postgres Failover Manager provide automatic failover to ensure high availability by monitoring and identifying database failures.

On the other hand, SQL Server includes several high availability tools such as log shipping, failover clusters, and replication. SQL Server availability groups, which operate around the clock, provide automatic hong kong whatsapp number data failover when certain conditions are met. However, this offering is only available in the enterprise edition of SQL Server.

PostgreSQL offers its users the procedural programming language PL/pgSQL to make it easier. Additional features to standard SQL in PostgreSQL include user-defined types, custom modules, extensions, JSON support, and additional options for triggers and other features.

SQL Server uses T-SQL, which resembles standard SQL. T-SQL includes additional support for data and string processing, procedural programming, and local variables.

If you want to better understand how systems cache and process requests, PostgreSQL isolates processes by treating them as separate processes from the operating system. Each database has a separate memory and runs its own process. This makes monitoring and management easier, but at the same time makes it difficult to scale multiple databases.

SQL Server uses a buffer pool that can be limited or increased based on processing needs. All work is done in a single pool, with no multiple pages, unlike PostgreSQL.

Both PostgreSQL and SQL Server support temporary tables, which allow you to store intermediate results of complex branching logic and complex procedures. Temporary tables can help improve database organization and performance by isolating intermediate information from essential information.
