Praktik terbaiknya adalah mengenkripsi traffic jaringan antara aplikasi Looker dan database Anda. Pertimbangkan salah satu opsi yang dijelaskan di halaman dokumentasi Mengaktifkan akses database yang aman.
Menginstal fungsi yang ditentukan pengguna (UDF) hash_md5
Sebelum mengonfigurasi Looker agar berfungsi dengan Teradata, Anda harus menginstal fungsi yang ditentukan pengguna (UDF) hash_md5 di server Teradata Anda. Anda dapat menemukan petunjuk untuk menginstal UDF di halaman download Teradata ini.
Menginstal driver JDBC Teradata
Jika memiliki instance Looker (asli), Anda harus mengonfigurasi driver Teradata sebelum membuat koneksi Looker. Petunjuk ini menjelaskan proses tersebut, dengan asumsi penggunaan skrip startup yang mirip dengan contoh yang disediakan di halaman GitHub looker-open-source.
Untuk menginstal driver, Anda harus mendapatkan dua file Teradata, menyertakannya sebagai bagian dari proses startup, dan menambahkan opsi untuk memberi tahu Looker agar mengakses driver.
Untuk membuat koneksi dari Looker ke database Anda, ikuti langkah-langkah berikut:
Di bagian Admin Looker, pilih Connections, lalu klik Add Connection.
Pilih Teradata dari menu drop-down Dialek.
Isi detail koneksi. Sebagian besar setelan umum untuk sebagian besar dialek database. Lihat halaman dokumentasi Menghubungkan Looker ke database Anda untuk mengetahui informasi selengkapnya.
Untuk memverifikasi bahwa koneksi berhasil, klik Uji. Lihat halaman dokumentasi Menguji konektivitas database untuk mengetahui informasi pemecahan masalah.
Untuk menyimpan setelan ini, klik Hubungkan.
Dukungan fitur
Agar Looker mendukung beberapa fitur, dialek database Anda juga harus mendukungnya.
Teradata mendukung fitur berikut mulai Looker 25.12:

[Install the `hash_md5` user-defined function (UDF) on your Teradata server](#install-udf).\n 2. [Install the Teradata JDBC driver](#install-jdbc-driver).\n 3. [Create the Looker connection to your database](#creating-the-connection-to-your-database).\n- For [Looker (Google Cloud core)](/looker/docs/looker-core-overview) instances, perform the following procedures:\n\n 1. [Install the `hash_md5` user-defined function (UDF) on your Teradata server](#install-udf).\n 2. [Create the Looker connection to your database](#creating-the-connection-to-your-database).\n\nEncrypting network traffic\n--------------------------\n\nIt is a best practice to encrypt network traffic between the Looker application and your database. Consider one of the options described on the [Enabling secure database access](/looker/docs/enabling-secure-db-access) documentation page.\n\nInstalling the `hash_md5` user-defined function (UDF)\n-----------------------------------------------------\n\nBefore configuring Looker to work with Teradata, you must install the `hash_md5` user-defined function (UDF) on your Teradata server. You can find instructions for installing the UDF on this [Teradata downloads](https://downloads.teradata.com/download/extensibility/md5-message-digest-udf) page.\n\nInstalling the Teradata JDBC driver\n-----------------------------------\n\nIf you have a Looker (original) instance, you will need to configure a Teradata driver before creating the Looker connection. These instructions describe that process, assuming use of a startup script that is similar to the examples that are provided on the [looker-open-source GitHub page](https://github.com/looker-open-source/customer-scripts/tree/master/startup_scripts).\n| **Note:** If you have a [Looker (Google Cloud core)](/looker/docs/looker-core-overview) instance, you can create a connection to a Teradata database without configuring a Teradata driver. After you [install the `hash_md5` user-defined function (UDF) on your Teradata server](#install-udf), you can go right to the [Creating the Looker connection to your database](#creating-the-connection-to-your-database) procedure on this page.\n\nTo install the driver, you will need to acquire two Teradata files, include them as part of the startup process, and add an option to tell Looker to access the driver.\n\nFollow the steps on the [Unpackaged JDBC drivers](/looker/docs/unpackaged-jdbc-drivers) documentation page using the following values:\n\n**driver symbol** : `teradata`\n\n**driver entry**: \n\n - name: teradata\n dir_name: teradata\n module_path: com.teradata.jdbc.TeraDriver\n\nFor the [step to put the driver in your dialect's directory](/looker/docs/unpackaged-jdbc-drivers#driver_directory), the paths to these files will look like this:\n\n- `looker/custom_jdbc_drivers/teradata/tdgssconfig.jar`\n- `looker/custom_jdbc_drivers/teradata/terajdbc4.jar`\n\nCreating the Looker connection to your database\n-----------------------------------------------\n\nTo create the connection from Looker to your database, follow these steps:\n\n1. In the **Admin** section of Looker, select **Connections** , and then click **Add Connection**.\n2. Select **Teradata** from the **Dialect** drop-down menu.\n3. Fill out the connection details. The majority of the settings are common to most database dialects. See the [Connecting Looker to your database](/looker/docs/connecting-to-your-db) documentation page for information.\n4. To verify that the connection is successful, click **Test** . See the [Testing database connectivity](/looker/docs/testing-db-connectivity) documentation page for troubleshooting information.\n5. To save these settings, click **Connect**.\n\nFeature support\n---------------\n\nFor Looker to support some features, your database dialect must also support them.\n\nTeradata supports the following features as of Looker 25.14:"]]
