**LastCreated**

LastCreated is a concept commonly associated with database management systems, particularly in relational databases, where it refers to a timestamp or identifier used to track when a record was last modified or created. This attribute is frequently utilized in applications requiring version control, audit trails, or time-sensitive data management.

In many database systems, such as MySQL, PostgreSQL, or SQL Server, the `LAST_UPDATED` or `LAST_MODIFIED` column (or similar) is automatically maintained by the database engine. These fields often store the exact time when a record was last altered, allowing users to query recent changes efficiently. Some databases also include a `CREATED` column to record when a record was initially inserted.

The LastCreated concept extends beyond traditional databases into other systems like NoSQL databases, where timestamps or version vectors may be used to manage data changes. In software development, it can also refer to the last modification date of a file or codebase, often stored in version control systems like Git, where metadata such as `git log` or commit timestamps provide insights into development activity.

In applications requiring real-time updates, LastCreated is often used in conjunction with pagination or cursor-based retrieval to fetch only the most recent records, improving performance by reducing unnecessary data queries. This is particularly useful in scenarios like social media feeds, live dashboards, or collaborative platforms where timely data is critical.
