India’s economy has undergone many transformations, but few changes have touched the daily lives of people as deeply as the way we make payments. From receiving toffees instead of coins as loose change to paying with a single tap on a smartphone, the journey of payments in India is a reflection of innovation, adaptability, and progress.

The Era of Cash and Toffees

For decades, cash ruled India’s markets. Small shops and street vendors relied entirely on notes and coins. When coins were in short supply, it was common for shopkeepers to hand out toffees or candies in place of small change. This quirky workaround became part of everyday transactions and highlighted how deeply dependent the economy was on cash.

But cash had its limits. Handling physical money was inconvenient and costly for banks and businesses and excluded millions of people who had no access to formal banking services.

Plastic Money and the First Steps Toward Digital

The introduction of debit and credit cards in the 1990s and 2000s brought the first wave of modern payments. ATMs offered flexibility, and card machines were introduced in big retail outlets. Yet, their reach was limited mostly to urban India.

In the early 2010s, mobile wallets such as Paytm and Freecharge gave people a taste of digital payments. They became popular for mobile recharges, bill payments, and online shopping. However, wallets required preloading money, which limited adoption in rural and semi-urban areas.

UPI: A Revolution in Payments

The real transformation arrived in 2016 with the launch of the Unified Payments Interface (UPI). For the first time, Indians could transfer money instantly from one bank account to another using just a mobile number or UPI ID.

Why UPI succeeded:

  • Simple and fast – instant payments, no need to preload wallets.
  • Inclusive – even small kirana shops could accept digital payments.
  • Trustworthy – transactions were bank-to-bank, with no middle layer.
  • Government support – initiatives like demonetization accelerated adoption.

Today, UPI is used everywhere—from buying vegetables to paying school fees. India now leads the world in real-time digital transactions, setting an example for other nations.

The Impact on India’s Economy

The move from toffees to UPI has reshaped the economy in many ways:

  • Financial inclusion: Millions of people gained access to the digital economy.
  • Transparency: Digital trails reduced black money and increased tax compliance.
  • Efficiency: Less cash handling saved costs for businesses and banks.
  • Empowerment: Small vendors and workers could now receive payments instantly.

What Lies Ahead

India’s payment story is still unfolding. Future developments include:

  • Credit on UPI, bringing easy micro-loans to millions.
  • Digital Rupee (CBDC), a central bank–backed digital currency.
  • Cross-border UPI, making international transactions faster and cheaper.

The journey from toffee-as-change to UPI payments is more than just a story of technology. It is about how a nation of over a billion people embraced innovation to make life simpler, fairer, and more connected.

India’s payment revolution shows that when technology meets trust, the possibilities are endless. And as the world looks at India’s model, one thing is certain—the future of money is not only digital, it’s Indian.

SQL Server 2014 CTP1 released on 26-Jun-2013, highly focused on data warehousing and business intelligence (BI) enhancements made possible through new in-memory capabilities built in to the core Relational Database Management System (RDBMS). As memory prices have fallen dramatically, 64-bit architectures have become more common and usage of multicore servers has increased, Microsoft has sought to tailor SQL Server to take advantage of these trends.

Hekaton is a Greek term for “factor of 100.” The aspirational goal of the team was to see 100 times performance acceleration levels. Hekaton also is a giant mythical creature, as well as a Dominican thrash-metal band, for what it’s worth.

In-Memory OLTP (formally known as code name “Hekaton”) is a new database engine component, fully integrated into SQL Server. It is optimized for OLTP workloads accessing memory resident data. In-Memory OLTP allows OLTP workloads to achieve remarkable improvements in performance and reduction in processing time. Tables can be declared as ‘memory optimized’ to take advantage of In-Memory OLTP’s capabilities. In-Memory OLTP tables are fully transactional and can be accessed using Transact-SQL. Transact-SQL stored procedures can be compiled into machine code for further performance improvements if all the tables referenced are In-Memory OLTP tables. The engine is designed for high concurrency and blocking is minimal. “Memory-optimized tables are stored completely differently than disk-based tables and these new data structures allow the data to be accessed and processed much more efficiently”

New buffer pool extension support to non-volatile memory such as solid state drives (SSDs) will increase performance by extending SQL Server in-memory buffer pool to SSDs for faster paging.

Here is very good explanation from Mr. Brent Ozar’s article on this ( http://www.brentozar.com/archive/2013/06/almost-everything-you-need-to-know-about-the-next-version-of-sql-server/ )

The New Feature xVelocity ColumnStore provides in-memory capabilities for data warehousing workloads that result in dramatic improvement for query performance, load speed, and scan rate, while significantly reducing resource utilization (i.e., I/O, disk and memory footprint). The new ColumnStore complements the existing xVelocity ColumnStore Index, providing higher compression, richer query support and updateability of the ColumnStore giving us the even faster load speed, query performance, concurrency and even lower price per terabyte.

Extending Memory to SSDs: Seamlessly and transparently integrates solid-state storage into SQL Server by using SSDs as an extension to the database buffer pool, allowing more in-memory processing and reducing disk IO.

Enhanced High Availability : New AlwaysOn features  availability Groups now support up to 8 secondary replicas that remain available for reads at all times, even in the presence of network failures. Failover Cluster Instances now support Windows Cluster Shared Volumes, improving the utilization of shared storage and increasing failover resiliency. Finally, various supportability enhancements make AlwaysOn easier to use.

Improved Online Database Operations: includes single partition online index rebuild and managing lock priority for table partition switch, greatly increasing enterprise application availability by reducing maintenance downtime impact.
