yrstruly Posted May 29, 2014 Share Posted May 29, 2014 Does Anybody know how do do this from end of 1st Q to the rest, Especially Creating the APis and Idexes and Bash code etc? 1. DB Schema Design - Design a basic database to store the following information + A fleet of Vehicles - Include details such as mileage, vin numbers etc + A pool of drivers - Include relevant documentation, e.g. Drivesr license, ID Book + A group of routes - Marking out GPS coords for directions etc. is not necessary, just include a start & end address as well as any other info you believe to be pertinent + A drivers schedule, tying the above 3 tables together 2. SQL skill test CREATE TABLE ¿tUSER¿ ( ¿id¿ bigint(20) NOT NULL AUTO§INCREMENT, ¿id§number¿ varchar(20) NOT NULL, ¿first§names¿ varchar(100) NOT NULL, ¿last§name¿ varchar(100) NOT NULL PRIMARY KEY (¿id¿), <<INDEXES>> ) CREATE TABLE ¿tPROFILE¿ ( ¿id¿ bigint(20) NOT NULL AUTO§INCREMENT, ¿tUSER§id¿ bigint(20) DEFAULT NULL, ¿tTYPES§id¿ bigint(20) DEFAULT NULL, ¿value¿ varchar(100) NOT NULL, PRIMARY KEY (¿id¿), <<INDEXES>> ) CREATE TABLE ¿tTYPES¿ ( ¿id¿ bigint(20) NOT NULL AUTO§INCREMENT, ¿type¿ varchar(100) NOT NULL DEFAULT '', ¿description¿ varchar(255) NOT NULL, ¿deleted¿ tinyint(1) NOT NULL DEFAULT '0', PRIMARY KEY (¿id¿), <<INDEXES>> ) Apply indexes to the above tables, and design a SINGLE query to retrieve a full list of user information based on: 2.A) an ID number 2. a cellphone number (¿Cellphone¿ is a record in the ¿tTYPES¿ table) 3. Write a re-usable script for importing information into the above 3 tables, from the example dsv file below: - NB - All data of the same type MUST be stored in the same format - NB2- You may assume that if a column doesn't seem to exist for a piece of data, that data type is listed in the tTYPES table <<BOF>> record§numberöid§numberöfirst nameölast nameömsisdnönetworköpointsöcard numberögender 312ö9101011234011öTest JunioröSmithö071 123 4321öMTNö73ö1241551413214444öM 313ö9012023213011öBoböSmithö27743334321öVodacomö3ö1231233232323244öM 314ö8706055678011öFranköFrankinsonö2771 156 1567ö8taö0ö1231123453214444öM 315ö9102078765011öMaryöVan Niekerkö+27(0)711236677öCellCö2ö1278933213214444öF 316ö9005074545011öSusanöWilsonö0821121124öCellCö705ö1231233216544444öF 317ö9101013232011öKatherineöJeevesö+271233214ö8taö112ö1231233678214444öF 318ö9101011234011öMatthewöMatthiasö0711111111öMTNöö1231555213214444öM 319ö9103126666011öMichaelöBayö085-6122-161ö8taö63ö1231244413214444öM 320ö7506023232300öTyroneöOlivierö711234322öCellCö89ö1234563213214444öM 321ö8901020304055öBurtöJacksonö071 4566544öVodacomö1ö4567233213214444öM <<EOF>> 4. After the data has been imported, Write a basic API to wrap the Database. Include the following function points: - Add a new User - Update a User's details - Delete a User - Search users 5. Describe what the following bash statement does: grep ¿date +%Y-%m-%d --date='1 day ago'¿ /path/to/file/FILE§PREFIX§Ö¿date +%Y%m%d --date='1 day ago'¿.dsv ö grep -v 'ERROR' ö cut -d "ö" -f 2 ö sed 's/Ü0/27/' 1. If a resturaunt serves: - 3 types of starters - 5 types of main - N types of drinks - 3 types of desserts + How many different meals are available, if you can order 1 item of each type? + How many different meals are available, if you can order 1 item of each type, BUT you can order 2 drinks as long as you do not order the same drink twice? + How many different meals are available, if you can only order a dessert OR a starter? 2. If you need to profile 1000 users, each with 3 different attributes, and each attribute has 4 possible values - before parsing any of the date: + What can we guarantee about the resultset? 3. A wild director appears. He uses "I want to profile my user database using an additional attribute!" - Describe a ¿super-effective¿ method which we can implement, which will allow us to handle an indeterminate number of this type of request. 4. If we have two seperate tables, the first detailing a list of registered club members, and the second detailing a list of competition entrants (assuming we have a key we can join on), what do/could the following resultsets represent: - The INTERSECT of the tables - The MINUS of the tables - The UNION of the tables Link to comment Share on other sites More sharing options...
Larry Posted May 30, 2014 Share Posted May 30, 2014 I don't think anyone is going to do your homework for you, but if you have specific questions, I'd be happy to help. Link to comment Share on other sites More sharing options...
