Tujuan utama dari penelitian ini adalah menganalisis, dan merancang data warehouse untuk PT. Indomarco Adi Prima. Data warehouse yang dirancang ini dapat membantu menjelaskan kondisi gambaran dan perkembangan perusahaan dengan cepat, jelas, akurat, dan praktis. Laporan yang dihasilkan dapat digunakan untuk membantu mengambil keputusan dalam menentukan langkah bagi perkembangan perusahaan. Metode analisis dilakukan dengan melakukan studi kepustakaan dan survei langsung di perusahaan, sedangkan metode perancangan dilakukan dengan merancang sebuah data warehouse dengan anatomi terpusat beserta aplikasinya yang akan digunakan untuk mengolah data dari data harian ke dalam data warehouse, selanjutnya menampilkan informasi yang berguna dan dibutuhkan oleh pihak eksekutif. Dari hasil penelitian ini, maka dibuatlah aplikasi berbasis data warehouse yang mampu mengolah dan menampilkan data menjadi informasi yang rinci, jelas, terintegrasi, historis, dan dalam cara yang fleksibel yang disesuaikan dengan keinginan dan kebutuhan user, serta mampu memberikan informasi mengenai performa yang tepat atas kondisi perusahaan secara keseluruhan, sehingga dapat meningkatkan produktivitas pihak eksekutif dalam analisis dan pengambilan keputusan. Penulis menyimpulkan bahwa kebutuhan akan data dan aplikasi pendukung pengambilan keputusan adalah penting bagi perusahaan, agar setiap keputusan yang diambil memiliki landasan yang kuat. Kata Kunci : analisis, perancangan, data warehouse, penjualan.
