Be-hind the scenes, StrlTrack uses the most respected and secure database, namely Postgresql. One of the many levels of backup is in real time to an identical replica database in the Cloud.

transactions take the form of single row insertions or modiﬁ-cations to existing rows. Examples are inserting a new sales record and updating a bank account balance. Analytic workloads are characterized by smaller trans-action volume (e.g. tens per second), but each transaction examines a signiﬁcant fraction of the tuples in a table. Ex-

5 Ways to Get More From PostgreSQL - EnterpriseDB
Many enterprises are choosing PostgreSQL because it offers performance, scalability and reliability that is comparable to enterprise databases like Oracle. 2.

Reconsidering Optimistic Algorithms for Relational DBMS
The performance measure for DBMS is the number of new-order transactions per second, and for commercial databases this can run to millions. Despite this, the specification requires each clerical task to take quite a long time: up to 20 seconds for a new order, so that in a 10-minute test run a single clerk can complete 16 new orders.
Moving Oracle workloads to the cloud: 5 key decisions
the norm is 8,000 transactions per second (TPS) or more in an Oracle environment in your data center, it will not be the same in the cloud. On-premises, you may have the luxury of a massive, fiber-channel-connected box where there is an average of 150,000 input/output operations per second (IOPS). You won t see that kind of high-end

Storage Performance and Resilience Testing
An IOPS test shows the amount of I/O operations, which the system can process as a whole, at di˜erent levels of parallel requests. It shows the upper bound of operations that can be performed by applications on the storage, i.e. for example it may help estimate a hard limit of how many database transactions can be performed on the storage.
Architecture Isolation and MVCC
transactions are read-only, there is no difficulty. Also there is no problem with two transactions trying to change the row (in this case, they are entering the queue and making changes one after another). The most interesting case is how the writing and reading transactions interact. There are two simple ways.

(DBMS). We used PostgreSQL DBMS for that purpose. PostgreSQL is an open source DBMS with the support for triggers and transactions. Both were heavily used in order to maintain database integrity and avoid possible race conditions. Connection to the database is made in abstract manner so PostgreSQL can be replaced by any equally functional DBMS.

A Framework to Process Iceberg Queries using Set-intersection
Many data mining queries are fundamentally iceberg queries. For instance, market analysts execute market basket queries on large data warehouses that store customer sales transactions. These queries identify user buying patterns, by finding item pairs (and triples) that are bought together by many customers [1, 3, 4].

volumes come with a base performance of three I/O Operations Per Second (IOPS), with abilities to burst up to 3,000 IOPS on a credit basis. As a rule of thumb, check the ReadIOPS and WriteIOPS metrics for the replication instance and be sure the sum of these values does not cross the base performance for that volume.
