endeksler

Endeksler is the Turkish term for indices, referring to indicators that quantify, compare, or track the value, position, or performance of a system. The concept appears in several domains, from mathematics to finance to information science, each with its own methods and conventions.

In mathematics and statistics, an index labels elements of a sequence or components of a structured object. Terms such as a1, a2, ..., an use indices to identify position. Multidimensional data use multi-index notation, for example a_{i,j}, to refer to specific entries. Indices help organize, access, and manipulate data and functions efficiently.

In economics and finance, endeksler denote benchmark aggregates that summarize the performance of a market segment. A stock index combines selected securities according to a weighting rule to produce a single measure of market performance. In Turkey, well-known examples include the BIST 100 Endeksi and other BIST indices, as well as sector indices like the Banking index. Inflation and price movements are tracked with price indices, such as TÜFE Endeksi (Consumer Price Index) and ÜFE Endeksi (Producer Price Index).

In information systems, indexing refers to structures and processes that speed up data retrieval. Indexes map values to storage locations, enabling faster searches and queries in databases and text retrieval systems.

Overall, endeksler function as versatile tools to quantify and compare changes, organize data, and provide reference points across disciplines.
