Db2

IBM's Db2 is the most low latency enterprises database which supports for faster realtime as well as supporting low latency transactions equipped with full availability. Our use case for in order to use Db2 is to store all our banking related datas ( user data, bank/ATM branches data, Transaction purpose ), Assets inventory and some data of our own datalake which helds massive amount of data for showcasing analysis for various use cases.

We use Db2 as the Application Databases that we have and the processes that utilize them at SSE/OVO Energy. A Db2 Sub-system can itself be part of a Db2 Data Sharing Group. Db2 Data Sharing allows us to spread the workload and resources of Db2 over more than one LPAR. The assigned Application databases are accessible through the Db2 sub-systems of the group. At SSE, we have several Data Sharing Groups. Each one has two sub-systems, these sub-systems running on separate LPARs. Each Data Sharing Group has its own unique name, there are several ways to connect to Db2 when wishing to access the databases. The Application that we use here is called the Customer System (also known as the CS Database). CS comprises 17 databases totaling over 1100 tables.

Db2 has been a critical component of our organization's data management strategy, delivering several advantages to satisfy our business needs. It helps us to achieve our goals. One of the main advantages of Db2 is its dependability, which has continuously supplied us with secure and rapid access to our data.

IBM Db2 is a highly scalable, secure, and reliable database management system. It has capabilities such as advanced query optimization and efficient resource management. The biggest problem that my company faces with third-party logistics is that every movement of every shipment is captured. And for that, we require a reliable and efficient database management system. This is where Db2 comes in. Various projects like landing profiles, weak links capturing in a logistics network, etc. are all dependent on Db2. All the Power BI dashboards are also linked with Db2 for real-time accurate KPIs visibility.

After almost 4 years with Db2, I can confirm its reliability and accurateness and many features. As an illustration of its stability, it handles our situation with many transactions without issues and complaints. Also, due to its cross-platform interoperability, our efficiency increased, and we gained useful information. Finally, troubleshooting is very easy if any issue arises and can be solved very easily with detailed documentation and a helpful community.

Db2 is used in factories, to collect all data about products produced. It is used to insert/follow up orders of products We also have a datawarehouse where we create all kind of statistics/reports

IBM Db2 is one of most highly reliable,scalable and high performance db tool I ever worked with.during my Tenure worked as a product admin my experience with this application is constantly demonstrated its reliability and comprehensive features set.it provide full set of data redundancy and 100% availabilitie like other famous db.

Our main student information system uses a Db2 backend. This allows us to store basic information on students, staff and parents.
We then use it to track academic marks, reports and pastoral comments.
We can then use a range of tools to produce reports and experts for different areas of our school.

DB2 helps design, store, and handle large collections of data. DB2 provides both on-premises and cloud hosting solutions. DB2 can be fine-tuned to scale according to the load, improving performance. DB2 can handle structured, unstructured, and relational data on one platform itself.

Db2 is an object-relational database. It supports database servers; it also extends to support object–relational features and non-relational structures like JSON and XML. It provides high availability and helps with zero downtime and no data loss. It also aids in data partitioning by indexing and delivering optimal performance since it has data governance in Unity catalogs in Data Lakehouse.

Our organization use IBM Db2 to leverages its features such as Performance Optimization, backup and recovery, and resource management to ensure the reliability, scalability and performance of our backend used for demanding API-driven applications. It also plays a crucial role in making sure data integrity, security and compliance with regulatory requirements.

It is used widely company wise by different department and different applications, mostly it is lagacy system, created in house or vendors. DB2 have very important company data, transnational and reporting.

We leverage Db2 as a reliable dependable powerful scalable relational database management system that handles massive data storage with all the data quality and governance enhancing value delivery delivered by relational databases architected for corporate cross functional integrations and actionability.

Db2 is the database of choice for all our mainframe applications in our organization. Many mission critical applications are using Db2 database to manage their work. It is a very high performance database. There are excellent tools available to manage the database such as Platinum etc. You can use it us dbeaver or other windows based software client.

Its a highly underrated DBMS system which has lot of capabilities.
We have been using this for large scale OLTP applications . It has good capability to handle huge number of concurrent users . We have few thousand's of users accessing this system. We have very minimal performance problems and very has good performance tuning solutions available . Implemented encryption as well.

Because Db2 is scalable, it can be used by both big and small businesses with different types of data requirements. To obtain data and test my applications using various data sets, I primarily utilize SQL scripts. The financial and demographic data that form the foundation of our system are ideal for the Db2 database. With all of our sensitive data, the system's security is ideal.

to collect all info in factories - consolidate info

DB2 runs the bulk of our company processes including inventory, accounting, manufacturing, order management, CRM, business intelligence, and data warehousing. It is the main database for nearly everything and is considered the source of record for most transactions. We also use it as the database for loading and cleansing data before interfacing with any other databases.

An essential part used in the company is the IBM Db2 software to provide the database management cloud solution on our mainframe infrastructure. Super reliable and integrates exceptionally with the Cobol language, offering excellent performance in queries that require a large workload on the DBMS. We've tested several and it was the only one that could handle our data stream and responses in milliseconds. IBM still provides support for the tool, which also has a large community, mainly banks, which help and contribute to solving doubts and programming.

Inventory, ingest and question open information designs utilizing a solitary stage that upholds tight joining with your information lake over cloud object capacity. While implementing of the data over cloud for analytics the queries, the implementation of data analytics over cloud is much simpler and efficient here. Provides a stage that limited grating for clients by being exceptionally viable with existing SQL code, and simple to incorporate with SAP applications.

We use DB2 as a generic database for a wide range of front end employee facing applications - HTML and non HTML based (proprietary user interface). We extensively use DB2 for our Lotus Notes application. This application is used for task tracking, logging, project management, change control requests, incident tracking and response tracking on those said incidents.

As a Db2 admin, among the projects I’ve handled that involved Db2 are:

• Setup of HADR Table Partitioning Upgrade of Db2 from 10.5 to 11.5 and Fix
• Pack Applications Database Replication using IBM WebSphere MQ
• Installation and setup of Db2 databases and client servers

Most of the issues I’ve encountered were related to:

• Restoration of local backup from one server to another
• Long duration of local backups HADR Replication

<ul><li>From the perspective of the engineer who designs the common infrastructure for our usage of Db2:</li></ul><ul><li>We use Db2 mostly for OLTP applications, some of them business critical with multi-million transactions per day</li><li>We also see increasing analytical workloads on these OLTP databases</li></ul>Underpinning infrastructure is IaaS VMs built on RHEL and deployed on:<br><ul><li>on-prem cloud platform (based on VMWare stacks)</li><li>public clouds like Azure, AWS, GCP</li></ul>
