The Reserve Bank of India set up a Working Group under S. H. Khan, then chairman of IDBI, to examine the roles of development financial institutions and banks; its 1998 report recommended that the two be harmonised and that India move towards universal banking, which is why the idea is…

CASA stands for current account and savings account balances. A current account earns no interest and a savings account earns a low rate, so the money a bank collects through them costs it far less than any other source, and gathering such balances from lakhs of individuals is exactly what…

The liquidity coverage ratio asks a bank to hold enough unencumbered high-quality liquid assets, mainly cash, balances with the central bank and government securities, to survive thirty calendar days of a severe stress scenario without fresh funding.

Asset classification moves in steps. An account that stays overdue beyond ninety days becomes a non-performing asset and is first called sub-standard; once it has remained sub-standard for more than twelve months it is reclassified as doubtful, and it is called a loss asset when the bank or its auditors…

A guarantee becomes a payment only if the customer fails to perform, so it is not added to the totals of the balance sheet; Form A shows guarantees, letters of credit, acceptances and forward exchange contracts separately as contingent liabilities, and bills for collection appear as a contra item.

The capital to risk-weighted assets ratio, or CRAR, is Tier 1 plus Tier 2 capital divided by risk-weighted assets, and the Reserve Bank of India requires Indian scheduled commercial banks to keep it at a minimum of nine per cent, with a capital conservation buffer of 2.5 per cent of…

Under the income recognition and asset classification norms followed by banks in India, a term loan becomes a non-performing asset when interest or an instalment of principal remains overdue for more than ninety days.

Section 29 of the Banking Regulation Act, 1949 requires every banking company to prepare, as on the last working day of its accounting year, a balance sheet and a profit and loss account in the forms set out in the Third Schedule to the Act.

The credit-deposit ratio, usually written as the CD ratio and given in per cent, shows how much of every hundred rupees of deposits a bank has lent out.

Net interest income, written as NII, is the core earning of a bank: the interest it collects on advances and investments less the interest it pays on deposits and borrowings.

CASA is short for current account and savings account, and the CASA ratio is current plus savings deposits divided by total deposits, shown as a percentage.

A deposit is money the bank owes back to the depositor, so it is a claim on the bank and is shown under liabilities in Form A of the Third Schedule to the Banking Regulation Act, 1949, along with capital, reserves and surplus, borrowings and other liabilities and provisions.

Apache Hive puts a table-like view over files stored in HDFS and lets an analyst write queries in HiveQL, a language close to SQL, which Hive then turns into jobs that run on the cluster, so that no Java programming is needed.

NoSQL databases drop the fixed table and row structure so that they can hold large and irregular data and spread it over many machines, and MongoDB is the best known document store, keeping records as documents in a format close to JSON.

Clustering is unsupervised because the data carries no labels: the algorithm itself groups similar records, k-means doing so by placing k centres and moving them until each record sits with its nearest centre.

ETL names the three steps through which data enters a warehouse: it is extracted from the operational systems that produced it, transformed so that formats, units, codes and duplicates are reconciled into one consistent shape, and then loaded into the warehouse tables.

It uses historical data with statistical models and machine learning to estimate what will probably happen next, such as which loan accounts are likely to slip into default or how much electricity a city will draw next summer.

Storage units climb in powers of two, each unit being 1,024 times the one below it, so 1,024 bytes make a kilobyte, 1,024 kilobytes a megabyte, 1,024 megabytes a gigabyte, 1,024 gigabytes a terabyte and 1,024 terabytes a petabyte.

The Apriori algorithm first finds the sets of items that appear together often enough to pass a support threshold, using the rule that any subset of a frequent set must itself be frequent, and then turns those frequent sets into rules measured by confidence.

In the process called Knowledge Discovery in Databases, or KDD, the stages run from selection of the relevant data, through cleaning and preprocessing, to transformation, then data mining, and finally interpretation and evaluation of what was found.
