  2. Cerner CCL - Wikipedia

    en.wikipedia.org/wiki/Cerner_CCL

    CCL is patterned after the Structured Query Language (SQL). All Cerner Millennium health information technology software uses CCL/Discern Explorer to select from, insert into, update into and delete from a Cerner Millennium database and allows a programmer to fetch data from an Oracle database and display it as the user wants to see.

  3. Shadow paging - Wikipedia

    en.wikipedia.org/wiki/Shadow_paging

    In computer science, shadow paging is a technique for providing atomicity and durability (two of the ACID properties) in database systems. A page in this context refers to a unit of physical storage (probably on a hard disk), typically of the order of 1 to 64 KiB. Shadow paging is a copy-on-write technique for avoiding in-place updates of

  4. Terminal pager - Wikipedia

    en.wikipedia.org/wiki/Terminal_pager

    A terminal pager, paging program or simply pager is a computer program used to view (but not modify) the contents of a text file moving down the file one line or one screen at a time. Some, but not all, pagers allow movement up a file. [ 1 ]

  5. Rollback (data management) - Wikipedia

    en.wikipedia.org/wiki/Rollback_(data_management)

    SQL refers to Structured Query Language, a kind of language used to access, update and manipulate database. In SQL, ROLLBACK is a command that causes all data changes since the last START TRANSACTION or BEGIN to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.

  6. Pagination - Wikipedia

    en.wikipedia.org/wiki/Pagination

    Pagination, also known as paging, is the process of dividing a document into discrete pages, either electronic pages or printed pages.. In reference to books produced without a computer, pagination can mean the consecutive page numbering to indicate the proper order of the pages, which was rarely found in documents pre-dating 1500, and only became common practice c. 1550, when it replaced ...

  7. Page table - Wikipedia

    en.wikipedia.org/wiki/Page_table

    The hashing function is not generally optimized for coverage - raw speed is more desirable. Of course, hash tables experience collisions. Due to this chosen hashing function, we may experience a lot of collisions in usage, so for each entry in the table the VPN is provided to check if it is the searched entry or a collision.

  8. Offset (computer science) - Wikipedia

    en.wikipedia.org/wiki/Offset_(computer_science)

    In this (original) meaning of offset, only the basic address unit, usually the 8-bit byte, is used to specify the offset's size. In this context an offset is sometimes called a relative address. In IBM System/360 instructions, a 12-bit offset embedded within certain instructions provided a range of between 0 and 4096 bytes. For example, within ...

  9. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    If paging is enabled, the base address in a segment descriptor is an address in a linear paged address space divided into 4 KB pages, so when that is added to the offset in the segment, the resulting address is a linear address in that address space; in IA-32, that address is then masked to be no larger than 32 bits. The result may be looked up ...
