  • Implementation of Data Backup and Synchronization Based on Identity Column Real Time Data Warehouse
    Lontar Komputer : Jurnal Ilmiah Teknologi Informasi, 2020
    Co-Authors: I Gede Adnyana, I Made Dwi Jendra Sulastra
    Abstract:

    Failure in the process of loading data from the Online Transactional Processing(OLTP) system to the Normalized Data Store (NDS) database can occur. This caused by a disruption in the network so that the OLTP system is unable to save data to the OLTP and NDS databases. Backup and synchronization data scenarios are needed to maintain data consistency and data availability. In this research, the process of data backup and synchronization is done by providing an Identity Column for the table in the OLTP database. An Identity Column is used to give status data, value '0' if the inserting process fails, and value '1' if successful. Data backup is done by storing temporary data into a CSV file format, then the CSV file is read, and an insert process is carried out into the OLTP database. After the insertion process into the OLTP database is successful, it continues with the synchronization process between the OLTP database and the NDS. Data synchronization between OLTP and NDS databases is done by checking the value of the Identity Column in each table in the OLTP database.

  • Performance evaluation of newly constructed NZCC for SAC-OCDMA using direct detection technique
    Photonic Network Communications, 2019
    Co-Authors: Kottakkaran Sooppy Nisar, Himali Sarangal, Simrandeep Singh Thapar
    Abstract:

    Recently, a new code structure, zero cross-correlation (ZCC) using anti-diagonal type-Identity-Column block matrices for spectral amplitude coding-optical code division multiple access (SAC-OCDMA) system, was proposed by K.S. Nisar. The new ZCC code (NZCC) is available for each natural number and has satisfactory code lengths. An effective OCDMA system must have efficient address codes to encode the source with almost zero correlation properties. ZCC eliminates phase-induced intensity noise that consequently improves the bit error rate. In this paper, performance analysis of the NZCC code employing SAC-OCDMA using the direct detection scheme is simulated and compared the efficiency with the other existing codes. The results show that for shorter ranges more number of users accommodated with high data rate by using NZCC code.

  • construction of zero cross correlation code using a type of anti diagonal Identity Column block matrices
    Optik, 2014
    Co-Authors: Kottakkaran Sooppy Nisar
    Abstract:

    Abstract This paper presents a new method for constructing zero cross correlation code with the help of anti-diagonal type-Identity-Column block matrices. The advantages of this code are easy code construction, existence for every natural number and acceptable code lengths. The numerical comparison shows that the newly constructed code is better code length and it supports more users than other Optical Spectrum Code Division Multiple Access (OSCDMA) codes.

  • Construction of IRA-LDPC codes based on Identity Column vectors
    2017 IEEE 9th International Conference on Communication Software and Networks (ICCSN), 2017
    Co-Authors: Li Peng, Kun Liang, Bo Zhou
    Abstract:

    A random-like framework of the IRA-LDPC codes based on the Identity Column vectors (ICV) was defined and created. A new family of the IRA-LDPC codes under the constraint of the framework was investigated using algebraic and random methods. Its structural features is that the large-sized sparse parity check matrix Hd corresponding to the information bits is extruded into two smaller-sized easy-to-compute matrices, respectively called base matrix and position matrix. The minimum decomposable unit of the parity-check matrix H is the ICV which can provide a wider selection range of code rates than the most extensively studied QC-LDPC codes. Some conditions for the IRA-LDPC code not to have any 4-girth were considered.
