Database Design 39 - Indexes (Clustered, Nonclustered, Composite Index)
 
13:28
This video covers the basics of indexes. Indexing is an extremely important step of database design. Without Indexes database queries can take a substantial amount of time and hog system resources. The main two classifications of indexes are clustered and non-clustered indexes. Clustered indexes are usually the primary key and determine how the data is actually stored in the table. These are the fastest and most effective. Non-clustered indexes sort a reference to data that is still fast but doesn't actually determine how the data is structured. The best tip I can give you is to use indexes but don't over use them. Having loads of indexes on columns that are barely ever in a where clause or join can bog down the database. This is because every time the table is updated the index must also be updated! When a database looks through a table for certain where conditions on a column that does not have an index, it does an entire table scan. This is not a good practice for large databases (or even small databases but not as bad). With an index the database will do an index seek and quickly find the data you are looking for. Composite indexes consist of two or more columns within one index. Use these when you plan on using the two columns together for a database query WHERE clause.

Stock Market Basics for Beginners: A stock index or stock market index is a measurement of the value of a section of the stock market. It is computed from the prices of selected stocks (typically a weighted average). It is a tool used by investors and financial managers to describe the market, and to compare the return on specific investments.

Stock Market Index | by Wall Street Survivor
 
01:44
What is a stock market index? Learn more at: https://www.wallstreetsurvivor.com An index, like the DOW, the S&P500 or the NASDAQ, is a sample of stocks that provide insight into the broader market. When someone says "the market is up 10 points today", they are referring to an index. By measuring the compilation of similar stocks instead of just one or two stocks, a stock index provides information about that particular market or segment. One of the most talked about and popular indexes is The Dow Jones Industrial Average (DJIA) which consists of 30 of the biggest companies in the U.S. Stock indices are typically related by some commonality: for example, the Dow Jones Wilshire 5000 is an index that measures or tracks almost every publicly traded stock in the United States. The Morgan Stanley Biotech Index is a small index that follows the biotechnology market. Each stock index has a specific focus that can provide highly specific or very generalized information.

How to use Excel Index Match (the right way)

Complete Excel Dashboard course: https://courses.xelplus.com/p/professional-excel-dashboards Check out my other courses below. Download workbook here: http://www.xelplus.com/excel-index-and-match How to do Index Match in Excel: The basics. Watch this video tutorial to find out how you can use Index & Match for more complex lookup problems. This video shows you how Index Match works with simple and to the point explanation. It first shows you how Index works on it's own and then how Match works and then puts the two Excel functions together. Why index match is better than vlookup & why use index match instead of vlookup? Here are 3 reasons why Excel experts generally substitute VLOOKUP with INDEX and MATCH. 1. Unlike VLOOKUP, which searches only to the right, INDEX and MATCH can look in both directions – left and right. 2. INDEX & MATCH can perform two-way lookups by both looking along the rows and along the columns to find the intersection within a matrix. 3. INDEX & MATCH is less prone to errors. Assume you have a VLOOKUP where the final value you want returned is in column N. Your lookup value is in column A. You need to highlight the entire A to N range and then provide your index number to be 14. If you happen to delete any of the in-between columns, you would have to update that index number. You don’t need to worry about this when you use INDEX & MATCH. All in all, INDEX and MATCH is more flexible than VLOOKUP. Here are some of the reasons why Excel experts generally substitute VLOOKUP with INDEX and MATCH. Note: Index match is not case sensitive Index explained: The first argument of INDEX is to give it an array. This array (range) should include your answer. You then need to specify how many rows to go down and how many columns to move to find the correct value. You cannot move outside the INDEX range. The syntax of INDEX is: • The range where the return value resides. • Number of rows to move down (the row index) • Number of columns to move to the right (the column Index). This argument is optional. If you only have one column, you can leave the column argument empty, otherwise, you need to specify the number of columns to move over, in the range. The MATCH function’s syntax is as follows: • Like VLOOKUP, Match needs a lookup (target) value. The user can reference a cell or directly type the value into the formula. • Lookup_array: The “list” (range) where the return values are located. • Match_type: 0 for an “exact” match. Index MATCH used together: When INDEX and MATCH are used together, the MATCH function finds the look up value’s row / column index and then hands this value off to the INDEX function to get the lookup value. ★ My Online Excel Courses ► https://courses.xelplus.com/ ✉ Subscribe & get my TOP 10 Excel formulas e-book for free https://www.xelplus.com/free-ebook/ EXCEL RESOURCES I Recommend: https://www.xelplus.com/resources/ Get Office 365: https://microsoft.msafflnk.net/15OEg Microsoft Surface: https://microsoft.msafflnk.net/c/1327040/451518/7593 GEAR Camera: https://amzn.to/2FLiFho Screen recorder: http://techsmith.pxf.io/c/1252781/347799/5161 Microphone: https://amzn.to/2DVKstA Lights: http://amzn.to/2eJKg1U More resources on my Amazon page: https://www.amazon.com/shop/leilagharani Note: This description contains affiliate links, which means at no additional cost to you, we will receive a small commission if you make a purchase using the links.

mysql tutorial for beginners (6/8) : Indexes
 
05:48
mysql tutorial for beginners (6/8) : Indexes As things stand, the table students works and can be searched without problem by MySQL—until it grows to more than a couple of hundred rows, At that point, database accesses will get slower and slower with every new row added, because MySQL has to search through every row whenever a query is issued. This is like searching through every book in a library whenever you need to look something up. Of course, you don’t have to search libraries that way, because they have either a card index system or, most likely, a database of their own. The way to achieve fast searches is to add an index, either when creating a table or at any time afterward. But the decision is not so simple. For example, there are different index types such as a regular INDEX, PRIMARY KEY, and FULLTEXT. Also, you must decide which columns require an index, a judgment that requires you to predict whether you will be searching any of the data in that column. And even when you’ve decided that, you still have the option of reducing index size by limiting the amount of each column to be indexed. If we imagine the searches that may be made on the students table, it becomes apparent that all of the columns may need to be searched. Anyway, go ahead and add an index to each of the columns, using the commands: ALTER TABLE students ADD INDEX(name(3)); An alternative to using ALTER TABLE to add an index is to use the CREATE INDEX command. They are equivalent, except that CREATE INDEX cannot be used for creating a PRIMARY KEY CREATE INDEX surname ON students (surname(5)); DESCRIBE students; These commands create indexes on both the name and surname columns, limiting name index to only the first 3 characters, and surname index to the first 5 characters. For instance, when MySQL indexes the following name: SAFAA It will actually store in the index only the first 3 characters: SAF This is done to minimize the size of the index, and to optimize database access speed. DESCRIBE command shows the key MUL for each column. This key means that multiple occurrences of a value may occur within that column, which is exactly what we want, as name or surname may appear many times. You don’t have to wait, until after creating a table to add indexes. In fact, doing so can be time-consuming, as adding an index to a large table can take a very long time. Therefore, let’s look at a command that creates the table students with indexes already in place. CREATE TABLE students ( Id_studnet SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(10) NOT NULL, surname VARCHAR(20) NOT NULL, email VARCHAR(30) NOT NULL, INDEX(name(3)), INDEX(surname(5)), ,PRIMARY KEY(id_studnet),UNIQUE(email)); Another important index, PK, its single unique key for each student to enable instant accessing of a row. The importance of having a key with a unique value for each row will come up when we start to combine data from different tables. You can add PK, while you create the table at the first time, or later by issuing the following command: ALTER TABLE students ADD PRIMARY KEY(id_student); The last important index, FULLTEXT index Unlike a regular index, MySQL’s FULLTEXT allows super-fast searches of entire columns of text. It stores every word in every data string in a special index that you can search using “natural language,” in a similar manner to using a search engine. It’s not strictly true that MySQL stores all the words in a FULLTEXT index, because it has a built-in list of more than 500 words that it chooses to ignore because they are so common that they aren’t very helpful for searching anyway. This list, called stopwords, includes the, as, is, of, and so on. The list helps MySQL run much more quickly when performing a FULLTEXT search and keeps database sizes down. FULLTEXT indexes can be created for CHAR, VARCHAR, and TEXT columns only. A FULLTEXT index definition can be given in the CREATE TABLE statement when a table is created, or added later using ALTER TABLE (or CREATE INDEX). Adding a FULLTEXT index to the table students for the columns name and surname ALTER TABLE classics ADD FULLTEXT(name,surname); this index is in addition to the ones already created and does not affect them You can now perform FULLTEXT searches across this pair of columns. If you find that MySQL is running slower than you think it should be when accessing your database, the problem is usually related to your indexes. Either you don’t have an index where you need one, or the indexes are not optimally designed. Tweaking a table’s indexes will often solve such a problem. In the next tutorial, we will learn about, using FOREIGN KEY Constraints and how to join tables together.

Tips for Trading the S&P 500 (US 500) Index 👍
 
06:24
● Trading the S&P 500. http://www.financial-spread-betting.com/indices/trading-ibex-35.html ● You can trade the S&P 500 index at Ayondo http://www.financial-spread-betting.com/spreadbetting/Ayondo-compare.html ✔ Please like the video and comment if you enjoyed - it helps a lot! But what is the S&P 500 Index? Standard and Poor 500; this represents the 500 largest companies in the United States spread across all kind of sectors so its a good barometer of the USA market. Some would argue that the Dow Jones isn't really representative of the USA market. The index started in 1923 with a much smaller number of stocks and it has expended since then. Obviously it is sensitive to USA domestic data like interest rates, non-farm payrolls, CPI,..etc and of course the global economy. The S&P 500 tends to move in tandem with the DOW most of the time except in times where there is some unusual happenings going on like some stock that is heavily weighted on the DOW that happens to be moving against it. As with the Dow, there are a number of events that you can watch for that will possibly impact the S&P 500. Market values are all about public confidence, and this is affected by Presidential pronouncements, Treasury Secretary speeches and the Federal Reserve Board (Feds) regular meetings.

How to Trade the German Dax (Germany 30 Index) 👍
 
15:56
● Trading the German DAX 30. http://www.financial-spread-betting.com/indices/spread-bet-dax-30.html ● You can trade the Dax at Ayondo http://www.financial-spread-betting.com/spreadbetting/Ayondo-compare.html ✔ Please like the video and comment if you enjoyed - it helps a lot! The DAX 30 represents the top 30 biggest listed companies in Germany [DAX Deutscher Aktienindex]. The DAX started trading in 1987 at a level of 1000 and hit 12888.95 in June 2017. The DAX index itself is market weighted - the higher the market cap of the company the more weighting its going to have on the index. The DAX or Germany 30 as it is sometimes referred to can be quite volatile. The DAX is obviously susceptible to EU data and the EURO. Constituents include Siemens, Bayer, SAP, BASF, Allianz, Daimler, Deutsche Telekom, Adidas, Fresenius, Deutsche Post, Linde and Munich Re. The Germany is somewhat correlated to other European indices like the FTSE 100 although its probably more volatile. With that kind of volatility you also get opportunities.
